✔️ Step-by-Step Repair Instructions
🔌
🔧 Step 1: Unplug dryer and remove front panel
- Walk to the back of the dryer and locate the power cord plugged into the wall outlet
- Grasp the plug (not the cord) and pull straight out from the wall outlet to disconnect power
- Move the power cord to the side so it won’t interfere with your work
- Open the dryer door fully
- Look at the top inner edge of the door opening – you’ll see 2 Phillips-head screws, one on the left side and one on the right side, each located approximately 2 inches from the top corner
- Use a Phillips #2 screwdriver to turn both screws counterclockwise and remove them completely
- Set these screws aside in a container
- Close the dryer door
- Stand directly in front of the dryer and place both hands on the left and right edges of the front panel, about halfway down the height
- Pull the entire front panel straight toward you at the bottom edge – it will pivot from clips at the top
- Once the bottom clears the base by approximately 2-3 inches, lift the entire panel upward and away from the top mounting clips
- The front panel (with door attached) will now be completely separated from the dryer – set it down flat in a safe location where the door won’t be damaged
- You now have full access to the drum, belt, motor assembly, and blower housing through the front opening
- The drum will be visible as a large silver cylinder
- The lint filter housing extends down from the top of the opening on the left side
🔍
🛠️ Step 2: Locate idler pulley assembly
- Position yourself at the open front of the dryer where you removed the front panel in the previous step.
- Look into the lower drum cavity toward the right side (when facing the dryer). The idler pulley assembly sits approximately 8-10 inches from the right edge and 4-5 inches up from the bottom base.
- Identify the idler pulley by its distinctive spring-loaded arm mechanism. You’ll see a white or silver metal bracket arm approximately 6 inches long that pivots on a mounting bolt.
- Trace the drum belt with your eyes from the drum itself downward. The belt loops around a small grooved wheel (the idler pulley wheel) that measures roughly 2 inches in diameter.
- Observe the tensioning spring attached to the idler arm. This silver coil spring stretches from the idler arm bracket to a mounting point on the dryer’s base frame, positioned approximately 3 inches to the left of the pulley wheel itself.
- Locate the single mounting bolt that secures the idler pulley bracket to the dryer frame. This bolt sits at the pivot point where the arm attaches to the base, approximately centered on the metal bracket arm.
- Note the idler pulley wheel’s position relative to the motor pulley (located directly behind and slightly lower than the idler pulley). The belt creates a triangular path: drum → idler pulley → motor pulley → back to drum.
- Verify you’ve identified the correct assembly by confirming these three components are connected: the spring-loaded pivoting arm, the grooved pulley wheel that the belt wraps around, and the tensioning spring pulling the arm backward.
🔍
⚙️ Step 3: Inspect pulley for wear or damage
- Locate the idler pulley assembly positioned on the right side of the drum, approximately 8 inches from the bottom of the dryer cabinet and 4 inches from the right panel.
- Grip the idler pulley wheel (the grooved plastic wheel that the belt wraps around) with your thumb and index finger.
- Attempt to spin the pulley wheel manually in a clockwise direction – it should rotate smoothly and quietly without resistance.
- Listen for grinding, squeaking, or scraping sounds as you spin the pulley – any noise indicates bearing failure requiring replacement.
- Continue spinning and watch for wobbling or side-to-side movement exceeding 1/8 inch – this indicates a worn bearing shaft.
- Examine the pulley wheel groove where the belt rides – look for shiny, glazed areas, cracks, or flat spots on the curved surface.
- Run your finger along the groove circumference – the surface should feel smooth, not rough or notched.
- Check for black rubber residue deposits in the groove from belt material transfer, indicating excessive friction and heat.
- Inspect the pulley wheel edges for cracks radiating outward from the center mounting hole.
- Examine the idler arm spring (the tensioning spring connecting the idler arm to the dryer base) for stretching – measure the spring length which should be 3.5 to 4 inches when at rest.
- Look at the pulley mounting bracket for cracks or stress fractures in the metal, especially where it attaches to the base.
- If you found any of the following, the idler pulley assembly (part number DC97-16782A) requires replacement: grinding noises, wobbling beyond 1/8 inch, visible cracks, glazing in the groove, or spring length exceeding 4.5 inches.
- If the pulley passes all inspections, proceed to the next diagnostic step.
🔍
🔩 Step 4: Check pulley bearing for smooth rotation
- Locate the idler pulley assembly positioned at the bottom right side of the dryer drum, approximately 4 inches from the front panel and 3 inches from the right wall.
- Grip the idler pulley wheel (the white or black plastic wheel, approximately 2 inches in diameter) with your dominant hand.
- Apply firm pressure with your thumb and rotate the pulley counterclockwise, completing 5-10 full rotations.
- Feel for any resistance, grinding sensation, or uneven movement as you spin the pulley—smooth rotation means the bearing is good.
- Listen for squealing, grinding, or clicking sounds during rotation—a healthy bearing produces no noise.
- Observe the pulley wheel wobbling side-to-side while rotating—movement exceeding 1/8 inch indicates a worn bearing.
- Place your fingertips on the outer edge of the pulley wheel and push it sideways (perpendicular to its rotation axis) with moderate pressure.
- Measure the lateral play—if the pulley moves more than 1/16 inch side-to-side, the bearing requires replacement.
- Inspect the center shaft of the idler pulley for a silvery metallic appearance—black discoloration or rust indicates bearing failure.
- Examine the pulley wheel edges for heat damage—melted plastic edges or brown discoloration signal bearing seizure from overheating.
- Rotate the pulley one final time—if it stops rotating within 2 seconds after release, the bearing has excessive friction and needs replacement.
- Check the tension spring attached to the idler pulley arm (the metal bracket holding the pulley)—confirm it pulls the pulley firmly against where the belt will sit.

đź“‹ Step 5: If bearing is rough, pulley needs replacement
- Locate the idler pulley assembly positioned at the front-left corner of the dryer drum support system, approximately 8 inches from the front panel and 4 inches from the left side wall.
- Grip the idler pulley wheel (the white or black plastic wheel that the belt rides on) with your thumb and index finger.
- Spin the pulley wheel rapidly in a clockwise direction – it should rotate smoothly and quietly for at least 5-10 revolutions before stopping.
- While the wheel is spinning, listen for any grinding, clicking, or scraping sounds that indicate bearing failure.
- Stop the wheel completely, then attempt to move it side-to-side (perpendicular to its rotation axis) by pushing with moderate finger pressure – there should be zero lateral movement or wobble.
- If you detect rough rotation, noise, or any side-to-side play exceeding 1/16 inch, the bearing has failed and the entire idler pulley assembly requires replacement (Samsung part number DC97-16782A).
- Use a 10mm socket wrench to remove the single hex bolt securing the idler pulley bracket to the dryer frame – turn counterclockwise 4-5 full rotations until the bolt releases.
- Lift the spring-loaded idler arm upward to release tension from the belt, then slide the belt off the idler pulley wheel.
- Pull the entire idler pulley assembly (bracket, spring, and pulley) away from the mounting point – it will come free as one complete unit.
- Position the new idler pulley assembly (part number DC97-16782A) onto the mounting hole, aligning the bracket’s circular opening with the threaded mounting point on the frame.
- Insert the 10mm hex bolt through the bracket hole and hand-thread it clockwise 2-3 turns to secure the assembly.
- Tighten the bolt to 8-10 ft-lbs using a torque wrench with 10mm socket – the bracket should sit flush against the frame without gaps.
🔍
âś… Step 6: Inspect tension spring for proper tension
- Locate the drum tension spring – it’s a silver coiled spring approximately 4 inches long, positioned at the bottom rear of the dryer, connecting the idler pulley arm to the dryer frame mount point on the right side.
- Press down on the idler pulley arm (the L-shaped metal arm that the spring attaches to) using your thumb with moderate pressure.
- Measure the resistance – the arm should move downward 1/2 inch to 3/4 inch before meeting firm resistance, requiring approximately 8-12 pounds of force.
- Release the arm and observe – it should snap back to its original position within 1 second with no hesitation or wobbling motion.
- Examine the spring coils visually – count the coils (should be 18-20 complete loops) and verify they are evenly spaced with no gaps larger than 1/4 inch between individual coils.
- Check both hook ends of the spring – the hooks should form complete 180-degree bends with no opening gaps, straightening, or cracks at the bend points.
- Look for rust, corrosion, or discoloration on the spring wire – any brown or orange spots indicate weakening, and dull gray areas instead of shiny silver indicate metal fatigue.
- Test for stretching by measuring the spring at rest – it should measure 3.75 to 4.25 inches from hook end to hook end when not under load.
- Pull the drum belt at its lowest point with your hand – with proper tension, you should be able to deflect the belt 1/2 inch downward with 5 pounds of finger pressure.
- If the spring stretches beyond 4.5 inches at rest, requires less than 5 pounds of force to compress the idler arm, or shows any physical damage, replacement is required (part number DC66-00361A).
🔄
🔍 Step 7: Remove old idler pulley
- Locate the idler pulley assembly mounted on a bracket approximately 8 inches from the front of the dryer drum, on the right side when facing the front of the machine.
- Identify the white plastic idler pulley wheel (approximately 2 inches in diameter) positioned between the motor pulley and the drum belt, with a metal tension arm extending from it.
- Push the idler pulley arm toward the motor using your hand to create slack in the belt—the arm will move approximately 2 inches and reduce tension on the belt loop.

- Check the tension spring attached to the idler pulley arm (the metal bracket holding the pulley)—confirm it pulls the pulley firmly against where the belt will sit.
âś…
đź“‹ Step 5: If bearing is rough, pulley needs replacement
- Locate the idler pulley assembly positioned at the front-left corner of the dryer drum support system, approximately 8 inches from the front panel and 4 inches from the left side wall.
- Grip the idler pulley wheel (the white or black plastic wheel that the belt rides on) with your thumb and index finger.
- Spin the pulley wheel rapidly in a clockwise direction – it should rotate smoothly and quietly for at least 5-10 revolutions before stopping.
- While the wheel is spinning, listen for any grinding, clicking, or scraping sounds that indicate bearing failure.
- Stop the wheel completely, then attempt to move it side-to-side (perpendicular to its rotation axis) by pushing with moderate finger pressure – there should be zero lateral movement or wobble.
- If you detect rough rotation, noise, or any side-to-side play exceeding 1/16 inch, the bearing has failed and the entire idler pulley assembly requires replacement (Samsung part number DC97-16782A).
- Use a 10mm socket wrench to remove the single hex bolt securing the idler pulley bracket to the dryer frame – turn counterclockwise 4-5 full rotations until the bolt releases.
- Lift the spring-loaded idler arm upward to release tension from the belt, then slide the belt off the idler pulley wheel.
- Pull the entire idler pulley assembly (bracket, spring, and pulley) away from the mounting point – it will come free as one complete unit.
- Position the new idler pulley assembly (part number DC97-16782A) onto the mounting hole, aligning the bracket’s circular opening with the threaded mounting point on the frame.
- Insert the 10mm hex bolt through the bracket hole and hand-thread it clockwise 2-3 turns to secure the assembly.
- Tighten the bolt to 8-10 ft-lbs using a torque wrench with 10mm socket – the bracket should sit flush against the frame without gaps.
🔍
âś… Step 6: Inspect tension spring for proper tension
- Locate the drum tension spring – it’s a silver coiled spring approximately 4 inches long, positioned at the bottom rear of the dryer, connecting the idler pulley arm to the dryer frame mount point on the right side.
- Press down on the idler pulley arm (the L-shaped metal arm that the spring attaches to) using your thumb with moderate pressure.
- Measure the resistance – the arm should move downward 1/2 inch to 3/4 inch before meeting firm resistance, requiring approximately 8-12 pounds of force.
- Release the arm and observe – it should snap back to its original position within 1 second with no hesitation or wobbling motion.
- Examine the spring coils visually – count the coils (should be 18-20 complete loops) and verify they are evenly spaced with no gaps larger than 1/4 inch between individual coils.
- Check both hook ends of the spring – the hooks should form complete 180-degree bends with no opening gaps, straightening, or cracks at the bend points.
- Look for rust, corrosion, or discoloration on the spring wire – any brown or orange spots indicate weakening, and dull gray areas instead of shiny silver indicate metal fatigue.
- Test for stretching by measuring the spring at rest – it should measure 3.75 to 4.25 inches from hook end to hook end when not under load.
- Pull the drum belt at its lowest point with your hand – with proper tension, you should be able to deflect the belt 1/2 inch downward with 5 pounds of finger pressure.
- If the spring stretches beyond 4.5 inches at rest, requires less than 5 pounds of force to compress the idler arm, or shows any physical damage, replacement is required (part number DC66-00361A).
🔄
🔍 Step 7: Remove old idler pulley
- Locate the idler pulley assembly mounted on a bracket approximately 8 inches from the front of the dryer drum, on the right side when facing the front of the machine.
- Identify the white plastic idler pulley wheel (approximately 2 inches in diameter) positioned between the motor pulley and the drum belt, with a metal tension arm extending from it.
- Push the idler pulley arm toward the motor using your hand to create slack in the belt—the arm will move approximately 2 inches and reduce tension on the belt loop.
- Slide the drive belt off the idler pulley wheel while maintaining pressure on the tension arm.
- Release the tension arm slowly, allowing it to return to its resting position.
- Locate the single 8mm hex head bolt securing the idler pulley assembly to its mounting bracket on the dryer’s lower frame.
- Use an 8mm socket wrench or nut driver to rotate the hex bolt counterclockwise 8-10 complete turns until the bolt is fully removed.
- Pull the idler pulley assembly straight away from the mounting bracket—it will separate completely once the bolt is removed.
- Examine the removed idler pulley wheel for the failure indicators you’re replacing it for: flattened bearing surfaces, wobbling wheel, rough rotation, or visible cracks in the white plastic wheel.
- Set the old idler pulley assembly aside with the removed hex bolt placed inside the pulley wheel opening so you don’t lose it.
- Verify the mounting bracket remains firmly attached to the dryer frame—wiggle it with your hand to confirm it’s secure and hasn’t loosened.
âś…
đź’ˇ Step 8: Install new idler pulley and tension spring
- Hold the new idler pulley (part number DC93-00634A) with the grooved wheel facing toward you and the mounting bracket extending backward.
- Locate the mounting hole on the rear drum support panel, positioned 3 inches below the motor mount bracket and 2 inches to the right of the blower housing.
- Insert the idler pulley’s threaded shaft through the mounting hole from the front side until the shaft protrudes approximately 1/2 inch through the back.
- Thread the hex nut onto the shaft from the rear side, turning clockwise by hand until finger-tight.
- Use a 10mm socket wrench to tighten the hex nut an additional 1/4 turn – the pulley should rotate freely without wobbling.
- Grip the coiled tension spring (silver/chrome, 2 inches long) with needle-nose pliers at the looped end.
- Hook the looped end onto the metal tab protruding from the idler pulley arm – the tab is located on the upper side of the pulley bracket.
- Pull the spring downward and slightly toward the left side of the dryer cabinet, extending it to approximately 4 inches in length.
- Hook the opposite looped end of the spring onto the anchor post welded to the base frame – this cylindrical post is located 5 inches directly below the idler pulley mounting point.
- Release the spring slowly – it will pull the idler pulley arm downward at a 45-degree angle.
- Push the idler pulley wheel toward the drum – it should spring back to its original position when released, demonstrating proper tension.
- Verify the pulley wheel groove is clean and free of debris by rotating it counterclockwise three complete revolutions with your finger.
✔️
⚡ Step 9: Ensure proper belt routing
- Locate the drum drive belt (part number 6602-001655, a multi-ribbed belt approximately 93 inches long) that you positioned earlier around the drum.
- Stand facing the front of the dryer and reach behind the drum to grasp the belt where it hangs down at the 6 o’clock position.
- Pull the belt underneath the drum, routing it so the ribbed side (grooved surface) faces toward the drum – the smooth flat side should face outward.
- Locate the motor pulley assembly mounted on the motor shaft at the lower rear right corner of the dryer cabinet, approximately 8 inches from the right wall and 4 inches above the base.
- Wrap the belt around the motor pulley in a clockwise direction when viewed from above, ensuring the ribbed side contacts the pulley wheel.
- Locate the idler pulley assembly positioned 3 inches to the left of the motor pulley – it’s a spring-loaded tensioner arm with a white plastic pulley wheel.
- Route the belt over the top of the idler pulley wheel, allowing the spring tension to pull the idler pulley upward against the belt.
- Rotate the drum clockwise by hand three complete revolutions while observing the belt movement – the belt should track centered on both the motor pulley and idler pulley without slipping off either side.
- Check that the belt sits flush against the rear drum surface with no twists, folds, or gaps between the belt and drum.
- Verify the idler pulley arm moves freely and maintains constant tension – you should feel approximately 5-8 pounds of resistance when manually pulling the idler pulley away from the belt.
- Confirm the belt alignment by sighting down from above – the belt should form a straight line from drum to idler pulley to motor pulley without angular deflection exceeding 5 degrees.
🧪
🎯 Step 10: Test dryer operation – should run quietly
- Plug the dryer power cord into the 240V wall outlet until it seats completely flush against the wall plate.
- Turn on the circuit breaker by flipping both legs of the double-pole breaker to the ON position (both switches should point toward the center of the panel).
- Open the dryer door and place 3-4 dry towels inside the drum to simulate a normal load and stabilize drum rotation.
- Close the door firmly until you hear a distinct click from the door latch engaging.
- Press the power button on the control panel at the top left corner – the display screen will illuminate showing “00” for minutes.
- Rotate the cycle selector knob clockwise two clicks to select “Air Fluff” (no heat cycle for initial testing).
- Press the START/PAUSE button – the drum should begin rotating within 2 seconds.
- Listen at the front of the dryer for the first 30 seconds – you should hear only smooth, continuous drum rotation with no grinding, squealing, or thumping sounds.
