✔️ Step-by-Step Repair Instructions
🔌
🔧 Step 1: Unplug dryer and remove front panel
- Locate the power cord at the rear of the dryer where it connects to the wall outlet.
- Grip the plug body (not the cord) and pull straight out from the wall outlet with firm, steady pressure.
- Move the plug to a location where it cannot accidentally be plugged back in during the repair.
- Open the dryer door fully.
- Locate the 2 Phillips-head screws inside the door opening at the top edge of the front panel, one positioned 3 inches from each side corner.
- Remove both screws using a Phillips #2 screwdriver, turning counterclockwise, and set them aside.
- Close the dryer door.
- Locate the lint screen housing at the top front of the dryer.
- Pull the lint screen completely out and set it aside.
- Look inside the lint screen cavity and locate 2 Phillips-head screws, one on the left side and one on the right side, recessed approximately 4 inches deep.
- Remove both screws using a Phillips #2 screwdriver and set them aside.
- Stand facing the front of the dryer and grip the top front panel edge with both hands, positioning your hands 8-10 inches apart near the center.
- Lift the front panel upward approximately 1 inch to disengage the 2 bottom tabs from their slots.
- Pull the bottom of the panel toward you while maintaining the upward lift until the panel is free.
- Disconnect the door switch wire connector located on the right side of the front panel by pulling the white plastic connector apart (the connector has a locking tab you must press while pulling).
- Set the front panel aside in a safe location where it won’t be damaged.
🔍
🛠️ Step 2: Inspect drive belt for breaks, cracks, or excessive wear
- Locate the drive belt wrapped around the drum – it’s a black or dark gray rubber belt approximately 92 inches long and ½ inch wide, positioned around the lower third of the dryer drum.
- Run your fingers along the entire inner surface (the side that contacts the pulleys) of the belt, moving around the complete circumference of the drum to feel for any cracks, splits, or soft deteriorated sections.
- Check for glazing by looking at the belt’s inner surface – a shiny, hardened appearance instead of a matte rubber finish indicates heat damage and slipping.
- Examine the belt edges on both sides for fraying, separating layers, or chunks of missing rubber.
- Look for any complete breaks or separations in the belt – if present, the belt will hang loose and the drum will spin freely by hand with no resistance.
- Measure the belt width at 3-4 different points around its length – if any section is less than 7/16 inch wide (compared to the standard ½ inch), the belt has worn excessively.
- Flex a section of the belt backward (opposite its normal curve) – if you see cracks appearing on the outer surface when bent, the rubber has deteriorated and needs replacement.
- Inspect the motor pulley and idler pulley surfaces where the belt rides – look for black rubber residue buildup, which indicates the belt has been slipping and depositing material.
- Check for proper tension by pressing down on the belt between the motor pulley and idler pulley with moderate finger pressure – it should deflect only ÂĽ to ½ inch, not hang loosely.
- If you found any cracks longer than ÂĽ inch, breaks, fraying, width reduction, excessive glazing, or the belt is completely broken, you need replacement belt part number 341241 (also known as W10127457).
🔍
⚙️ Step 3: Check entire belt path for obstructions
- Locate the idler pulley positioned at the bottom right of the drum cavity, approximately 8 inches from the right side panel and 4 inches back from the front opening.
- Run your fingers along the grooved surface of the idler pulley wheel, rotating it manually to feel for any lint buildup, fabric threads, or debris lodged in the groove where the belt rides.
- Move to the motor pulley located at the bottom rear-left corner of the dryer cabinet, approximately 6 inches from the left side and 3 inches from the back panel.
- Inspect the motor pulley wheel by rotating it counterclockwise with your hand, checking the belt groove for accumulated lint, coins, buttons, or fabric fibers that create a fuzzy texture.
- Trace the belt path with your hand from the motor pulley, along the bottom front of the drum (the portion you can now see with the drum lifted or removed), checking for any objects that may have fallen into the belt channel.
- Examine the drum support rollers—there are 2 rear rollers mounted on a shaft at the back of the cabinet, positioned 4 inches from each side—by spinning each roller and checking for lint wrapped around the axle shafts.
- Look underneath where the drum normally sits for any foreign objects: socks, coins, buttons, or jewelry that may have fallen through the lint filter housing.
- Use a shop vacuum with a crevice attachment to remove all lint and debris from the idler pulley groove, motor pulley groove, and the entire belt path channel along the cabinet bottom.
- Wipe the motor pulley and idler pulley surfaces with a dry cloth to remove any residual lint that could cause belt slippage.
- Verify all pulleys now spin freely without resistance or scraping sounds when rotated by hand—each should complete a full rotation smoothly within 1-2 seconds of applying light finger pressure.
🔄
🔩 Step 4: Remove old belt from motor pulley and idler
- Locate the idler pulley assembly on the right side of the dryer, approximately 8 inches from the bottom and 4 inches from the right panel – it’s a spring-loaded wheel mounted on a metal bracket.
- Identify the motor pulley directly below the idler pulley, positioned at the rear-bottom corner of the dryer drum – this is the smaller pulley (approximately 2 inches diameter) with silver metal finish.
- Use your right hand to push the idler pulley assembly to the left (toward the center of the dryer) by applying firm pressure on the idler wheel itself – this compresses the tension spring and creates slack in the belt.
- While maintaining pressure on the idler pulley with your right hand, use your left hand to lift the belt off the motor pulley by pulling it upward and away from the grooved wheel.
- Continue holding the idler pulley compressed and slide the belt off the idler pulley wheel by pulling it toward you.
- Release the idler pulley slowly – you’ll hear a slight spring tension sound as it returns to its resting position.
- Pull the entire belt forward through the gap between the drum and the front bulkhead (the metal panel at the front of the dryer cavity).
- Remove the belt completely from the dryer cabinet and set it aside for comparison with your replacement belt.
- Inspect the motor pulley surface – it should be smooth and silver with a V-shaped groove running around its circumference approximately 0.5 inches wide.
- Check the idler pulley wheel for smooth rotation by spinning it with your finger – it should rotate freely without grinding or catching (2-3 full rotations when flicked).
- Verify the tension spring attached to the idler assembly is intact and shows no signs of stretching or damage – the coils should be evenly spaced and uniform.
🔍
đź“‹ Step 5: Inspect idler pulley for wear and smooth operation
- Locate the idler pulley assembly positioned on the right side of the drum motor, approximately 3 inches below the drum’s bottom edge and 8 inches from the dryer’s right panel.
- Identify the idler pulley wheel (white or cream-colored plastic wheel, approximately 2 inches in diameter) mounted on a metal spring-loaded arm that maintains tension on the drum belt.
- Grip the idler pulley wheel between your thumb and index finger while the belt is still in place on the pulley.
- Attempt to spin the pulley wheel clockwise and counterclockwise—it should rotate freely with minimal resistance and no grinding sensation.
- Listen for any squeaking, grinding, or scraping sounds during rotation, which indicate worn bearings requiring replacement.
- Check for visible flat spots on the pulley wheel’s outer rim where the belt rides—the surface should be completely round without any worn grooves deeper than 1/16 inch.
- Examine the pulley wheel for cracks radiating from the center bearing hole outward toward the rim.
- Move the pulley wheel side-to-side (perpendicular to its rotation axis)—acceptable play is less than 1/8 inch; excessive wobble indicates a worn bearing assembly.
- Inspect the metal mounting bracket and spring arm for cracks, especially where the spring attaches to the pulley arm, approximately 2 inches above the pulley wheel.
- Check the spring tension by pressing the idler arm toward the motor—it should require moderate hand pressure and return immediately to its extended position when released.
- If the pulley spins freely without noise, shows no flat spots or cracks, has minimal side-to-side play, and the spring provides firm resistance, the idler pulley assembly passes inspection and requires no replacement.
- If any defects are present, note the idler pulley part number (typically W10547290 or 279640 for this model, stamped on the metal bracket).
🔍
âś… Step 6: Check motor pulley for damage
- Locate the motor pulley on the drive motor shaft – it’s a black plastic or metal wheel approximately 2.5 inches in diameter positioned at the front of the motor where the drum belt wraps around.
- Grip the motor pulley firmly with your hand and attempt to move it side-to-side perpendicular to the shaft axis – there should be zero lateral movement.
- Check for cracks by examining the entire circumference of the pulley, rotating it 360 degrees while looking at both the outer rim and the center hub where it attaches to the motor shaft.
- Inspect the belt groove (the channel where the drum belt sits) for wear by running your index finger around the entire circumference – the groove should be smooth and uniform with no flat spots, chips, or rough edges.
- Look at the pulley’s mounting position on the motor shaft – it should sit flush against the motor housing with no visible gap exceeding 1/16 inch.
- Grasp the pulley and attempt to pull it straight off the motor shaft using moderate hand pressure – it should remain firmly attached and not slide.
- Examine the setscrew (if present) on the side of the pulley hub using a flashlight – this is a small Allen-head screw typically 3/32 inch that secures the pulley to the flat side of the motor shaft.
- Check the inner bore of the pulley by looking through the center opening – you should see a D-shaped or half-moon cutout that matches the motor shaft profile.
- Verify pulley alignment by placing a straightedge across the drum pulley at the rear and extending it forward to the motor pulley – both pulleys should align within 1/8 inch of the same plane.
- If you identified cracks, excessive wear in the belt groove, looseness on the shaft, or misalignment exceeding 1/8 inch, the pulley requires replacement with part number 279640.

🔍 Step 7: Install new drive belt following proper routing
- Position the new belt (part number 341241) around the drum with the ribbed side facing inward, touching the drum’s metal surface.
- Push the drum approximately 2-3 inches toward the rear of the dryer cabinet to create slack in the belt positioning.
- Locate the motor shaft pulley at the bottom front of the dryer, approximately 8 inches from the right side panel and 4 inches back from the front bulkhead.
- Route the belt underneath the drum, bringing both ends down and forward to form a V-shape pointing toward the motor assembly.
- Loop the belt around the motor shaft pulley first, ensuring the grooved side of the belt sits inside the pulley groove with ribs engaged.
- Locate the spring-loaded idler pulley directly to the left of the motor pulley, approximately 3 inches away, attached to a metal tension arm.
- Pull the idler pulley toward you (toward the front of the dryer) using your left hand to create tension space.
- While holding the idler pulley forward, wrap the belt around the idler pulley with your right hand, keeping the ribbed side facing inward against the pulley surface.
- Release the idler pulley slowly—you’ll feel approximately 8-12 pounds of spring tension pull the pulley back, tightening the belt automatically.
- Rotate the drum manually clockwise 3-4 complete revolutions to verify the belt tracks centered on the drum without slipping off either side edge.
- Look at the belt path from the front: it should form a continuous loop from drum top, down around motor pulley, through idler pulley, and back up to drum.
- Push down on the belt between the motor pulley and idler pulley—it should have approximately ½ inch of deflection with firm finger pressure, indicating proper tension.
✔️
đź’ˇ Step 8: Ensure belt is properly seated on all pulleys
- Locate the motor pulley at the bottom front of the dryer, approximately 8 inches from the right side panel and 4 inches from the front bulkhead.
- Verify the belt is seated in the grooved channel of the motor pulley—the ribbed side of the belt (side with multiple small ridges) must contact the pulley surface, not the smooth outer side.
- Rotate the motor pulley clockwise by hand one full revolution while watching the belt remain centered in the pulley groove without slipping to either edge.
- Move to the idler pulley, located 3 inches directly above and slightly left of the motor pulley—this is the spring-loaded pulley approximately 2 inches in diameter.
- Check that the belt wraps around the idler pulley with the ribbed side making contact, and the pulley sits centered on the belt width without touching either belt edge.
- Push the idler pulley toward the motor with your index finger—it should move approximately 1/2 inch against spring tension and return smoothly when released.
- Follow the belt path to the drum at the rear, where it wraps around the entire drum circumference at the drum’s rear edge.
- Inspect the belt position on the drum—it should sit flat against the drum surface approximately 1 inch from the drum’s back panel, running parallel to the rear edge.
- Reach inside and rotate the drum clockwise by hand two complete revolutions, watching all three contact points (motor pulley, idler pulley, and drum) to confirm the belt stays centered and doesn’t walk off any pulley.
- While rotating the drum, listen for a smooth, quiet operation—properly seated belts produce no squealing, slapping, or rubbing sounds.
- Check that the belt maintains consistent tension throughout rotation without any slack sections appearing at any pulley position.
✔️
⚡ Step 9: Verify proper belt tension
- Locate the drum belt wrapped around the drum at the bottom rear section, approximately 4 inches from the floor of the dryer cabinet.
- Press down on the belt at the top center of the drum with your index finger using moderate pressure (approximately 5 pounds of force).
- Measure the belt deflection – the belt should move downward between 1/4 inch and 1/2 inch when pressed. Use a ruler placed vertically against the drum surface to measure this movement accurately.
- If the belt deflects more than 1/2 inch, the tension is too loose. Remove the drum and reposition the belt following the routing pattern: around the drum groove, under the idler pulley (located at the bottom right, 3 inches from the right edge), and around the motor pulley.
- Rotate the drum by hand 3 complete revolutions clockwise while listening for any squealing, rubbing, or clicking sounds that indicate improper belt seating.
- Check that the belt sits centered in the drum’s belt channel groove – no more than 1/8 inch deviation to either side of the channel.
- Examine the idler pulley arm at the bottom right corner. The spring-loaded arm should hold tension with the pulley positioned approximately 2 inches away from the motor pulley when at rest.
- Verify the belt shows no twisting along its length – it should lie completely flat against all three contact points: drum, idler pulley, and motor pulley.
- Plug in the dryer and run it empty for 30 seconds on the air fluff setting. The drum should rotate smoothly without slipping, hesitation, or unusual noise.
- Unplug the dryer again. Recheck the belt deflection measurement one final time – it should remain between 1/4 inch and 1/2 inch after the test run.

- Identify the motor pulley directly below the idler pulley, positioned at the rear-bottom corner of the dryer drum – this is the smaller pulley (approximately 2 inches diameter) with silver metal finish.
- Use your right hand to push the idler pulley assembly to the left (toward the center of the dryer) by applying firm pressure on the idler wheel itself – this compresses the tension spring and creates slack in the belt.
- While maintaining pressure on the idler pulley with your right hand, use your left hand to lift the belt off the motor pulley by pulling it upward and away from the grooved wheel.
- Continue holding the idler pulley compressed and slide the belt off the idler pulley wheel by pulling it toward you.
- Release the idler pulley slowly – you’ll hear a slight spring tension sound as it returns to its resting position.
- Pull the entire belt forward through the gap between the drum and the front bulkhead (the metal panel at the front of the dryer cavity).
- Remove the belt completely from the dryer cabinet and set it aside for comparison with your replacement belt.
- Inspect the motor pulley surface – it should be smooth and silver with a V-shaped groove running around its circumference approximately 0.5 inches wide.
- Check the idler pulley wheel for smooth rotation by spinning it with your finger – it should rotate freely without grinding or catching (2-3 full rotations when flicked).
- Verify the tension spring attached to the idler assembly is intact and shows no signs of stretching or damage – the coils should be evenly spaced and uniform.
🔍
đź“‹ Step 5: Inspect idler pulley for wear and smooth operation
- Locate the idler pulley assembly positioned on the right side of the drum motor, approximately 3 inches below the drum’s bottom edge and 8 inches from the dryer’s right panel.
- Identify the idler pulley wheel (white or cream-colored plastic wheel, approximately 2 inches in diameter) mounted on a metal spring-loaded arm that maintains tension on the drum belt.
- Grip the idler pulley wheel between your thumb and index finger while the belt is still in place on the pulley.
- Attempt to spin the pulley wheel clockwise and counterclockwise—it should rotate freely with minimal resistance and no grinding sensation.
- Listen for any squeaking, grinding, or scraping sounds during rotation, which indicate worn bearings requiring replacement.
- Check for visible flat spots on the pulley wheel’s outer rim where the belt rides—the surface should be completely round without any worn grooves deeper than 1/16 inch.
- Examine the pulley wheel for cracks radiating from the center bearing hole outward toward the rim.
- Move the pulley wheel side-to-side (perpendicular to its rotation axis)—acceptable play is less than 1/8 inch; excessive wobble indicates a worn bearing assembly.
- Inspect the metal mounting bracket and spring arm for cracks, especially where the spring attaches to the pulley arm, approximately 2 inches above the pulley wheel.
- Check the spring tension by pressing the idler arm toward the motor—it should require moderate hand pressure and return immediately to its extended position when released.
- If the pulley spins freely without noise, shows no flat spots or cracks, has minimal side-to-side play, and the spring provides firm resistance, the idler pulley assembly passes inspection and requires no replacement.
- If any defects are present, note the idler pulley part number (typically W10547290 or 279640 for this model, stamped on the metal bracket).
🔍
âś… Step 6: Check motor pulley for damage
- Locate the motor pulley on the drive motor shaft – it’s a black plastic or metal wheel approximately 2.5 inches in diameter positioned at the front of the motor where the drum belt wraps around.
- Grip the motor pulley firmly with your hand and attempt to move it side-to-side perpendicular to the shaft axis – there should be zero lateral movement.
- Check for cracks by examining the entire circumference of the pulley, rotating it 360 degrees while looking at both the outer rim and the center hub where it attaches to the motor shaft.
- Inspect the belt groove (the channel where the drum belt sits) for wear by running your index finger around the entire circumference – the groove should be smooth and uniform with no flat spots, chips, or rough edges.
- Look at the pulley’s mounting position on the motor shaft – it should sit flush against the motor housing with no visible gap exceeding 1/16 inch.
- Grasp the pulley and attempt to pull it straight off the motor shaft using moderate hand pressure – it should remain firmly attached and not slide.
- Examine the setscrew (if present) on the side of the pulley hub using a flashlight – this is a small Allen-head screw typically 3/32 inch that secures the pulley to the flat side of the motor shaft.
- Check the inner bore of the pulley by looking through the center opening – you should see a D-shaped or half-moon cutout that matches the motor shaft profile.
- Verify pulley alignment by placing a straightedge across the drum pulley at the rear and extending it forward to the motor pulley – both pulleys should align within 1/8 inch of the same plane.
- If you identified cracks, excessive wear in the belt groove, looseness on the shaft, or misalignment exceeding 1/8 inch, the pulley requires replacement with part number 279640.

🔍 Step 7: Install new drive belt following proper routing
- Position the new belt (part number 341241) around the drum with the ribbed side facing inward, touching the drum’s metal surface.
- Push the drum approximately 2-3 inches toward the rear of the dryer cabinet to create slack in the belt positioning.
- Locate the motor shaft pulley at the bottom front of the dryer, approximately 8 inches from the right side panel and 4 inches back from the front bulkhead.
- Route the belt underneath the drum, bringing both ends down and forward to form a V-shape pointing toward the motor assembly.
- Loop the belt around the motor shaft pulley first, ensuring the grooved side of the belt sits inside the pulley groove with ribs engaged.
- Locate the spring-loaded idler pulley directly to the left of the motor pulley, approximately 3 inches away, attached to a metal tension arm.
- Pull the idler pulley toward you (toward the front of the dryer) using your left hand to create tension space.
- While holding the idler pulley forward, wrap the belt around the idler pulley with your right hand, keeping the ribbed side facing inward against the pulley surface.
- Release the idler pulley slowly—you’ll feel approximately 8-12 pounds of spring tension pull the pulley back, tightening the belt automatically.
- Rotate the drum manually clockwise 3-4 complete revolutions to verify the belt tracks centered on the drum without slipping off either side edge.
- Look at the belt path from the front: it should form a continuous loop from drum top, down around motor pulley, through idler pulley, and back up to drum.
- Push down on the belt between the motor pulley and idler pulley—it should have approximately ½ inch of deflection with firm finger pressure, indicating proper tension.
✔️
đź’ˇ Step 8: Ensure belt is properly seated on all pulleys
- Locate the motor pulley at the bottom front of the dryer, approximately 8 inches from the right side panel and 4 inches from the front bulkhead.
- Verify the belt is seated in the grooved channel of the motor pulley—the ribbed side of the belt (side with multiple small ridges) must contact the pulley surface, not the smooth outer side.
- Rotate the motor pulley clockwise by hand one full revolution while watching the belt remain centered in the pulley groove without slipping to either edge.
- Move to the idler pulley, located 3 inches directly above and slightly left of the motor pulley—this is the spring-loaded pulley approximately 2 inches in diameter.
- Check that the belt wraps around the idler pulley with the ribbed side making contact, and the pulley sits centered on the belt width without touching either belt edge.
- Push the idler pulley toward the motor with your index finger—it should move approximately 1/2 inch against spring tension and return smoothly when released.
- Follow the belt path to the drum at the rear, where it wraps around the entire drum circumference at the drum’s rear edge.
- Inspect the belt position on the drum—it should sit flat against the drum surface approximately 1 inch from the drum’s back panel, running parallel to the rear edge.
- Reach inside and rotate the drum clockwise by hand two complete revolutions, watching all three contact points (motor pulley, idler pulley, and drum) to confirm the belt stays centered and doesn’t walk off any pulley.
- While rotating the drum, listen for a smooth, quiet operation—properly seated belts produce no squealing, slapping, or rubbing sounds.
- Check that the belt maintains consistent tension throughout rotation without any slack sections appearing at any pulley position.
✔️
⚡ Step 9: Verify proper belt tension
- Locate the drum belt wrapped around the drum at the bottom rear section, approximately 4 inches from the floor of the dryer cabinet.
- Press down on the belt at the top center of the drum with your index finger using moderate pressure (approximately 5 pounds of force).
- Measure the belt deflection – the belt should move downward between 1/4 inch and 1/2 inch when pressed. Use a ruler placed vertically against the drum surface to measure this movement accurately.
- If the belt deflects more than 1/2 inch, the tension is too loose. Remove the drum and reposition the belt following the routing pattern: around the drum groove, under the idler pulley (located at the bottom right, 3 inches from the right edge), and around the motor pulley.
- Rotate the drum by hand 3 complete revolutions clockwise while listening for any squealing, rubbing, or clicking sounds that indicate improper belt seating.
- Check that the belt sits centered in the drum’s belt channel groove – no more than 1/8 inch deviation to either side of the channel.
- Examine the idler pulley arm at the bottom right corner. The spring-loaded arm should hold tension with the pulley positioned approximately 2 inches away from the motor pulley when at rest.
- Verify the belt shows no twisting along its length – it should lie completely flat against all three contact points: drum, idler pulley, and motor pulley.
- Plug in the dryer and run it empty for 30 seconds on the air fluff setting. The drum should rotate smoothly without slipping, hesitation, or unusual noise.
- Unplug the dryer again. Recheck the belt deflection measurement one final time – it should remain between 1/4 inch and 1/2 inch after the test run.
