🔧 Step 1: Unplug dryer and remove front panel

  1. Move to the back of the dryer and locate the power cord where it enters the wall outlet.
  2. Grasp the plug (not the cord) and pull straight out from the wall outlet with firm pressure.
  3. Verify the dryer is unplugged by attempting to turn the control panel on—nothing should light up or respond.
  4. Open the dryer door fully to access the interior.
  5. Look at the top edge of the door opening and locate two Phillips-head screws, one on the left side and one on the right side, approximately 2 inches from each corner.
  6. Use a Phillips-head #2 screwdriver to remove these 2 screws completely and set them aside.
  7. Close the dryer door.
  8. Locate the lint filter housing at the top front of the dryer and remove the lint trap completely.
  9. Look inside the lint trap opening and identify 2 Phillips-head screws at the bottom of the cavity—one on the left, one on the right.
  10. Remove these 2 screws using your Phillips-head #2 screwdriver.
  11. Move to the front bottom of the dryer and locate the 2 plastic tabs on either side of the front panel, approximately 3-4 inches from each bottom corner.
  12. Insert a flathead screwdriver into the gap between the front panel and cabinet at the first tab location and pry gently outward to release the tab.
  13. Repeat on the opposite side to release the second tab.
  14. Lift the entire front panel straight up approximately 1-2 inches until it clears the bottom locating tabs, then pull the panel toward you at the top.
  15. Set the front panel aside in a safe location where it won’t be damaged.

🔧

🛠️ Step 2: Remove drum by lifting it out (may need to remove belt first)

  1. Locate the drum belt wrapped around the drum’s outer circumference – it’s a black rubber belt approximately 3/8 inch wide that runs around the entire drum perimeter.
  2. Reach underneath the front edge of the drum and grasp the belt with your right hand.
  3. Pull the belt away from the drum surface while simultaneously rotating the drum counterclockwise with your left hand – this releases tension on the belt.
  4. Continue rotating the drum 2-3 full rotations while holding the belt loose until it completely disengages from the drum.
  5. Pull the belt off the drum motor pulley located at the bottom rear of the cabinet, approximately 8 inches from the back wall and centered left-to-right.
  6. Set the belt aside outside the dryer cabinet.
  7. Position yourself directly in front of the open dryer cavity, standing centered with the drum opening.
  8. Place both hands on the front edge of the drum at the 10 o’clock and 2 o’clock positions.
  9. Lift the front edge of the drum upward approximately 4 inches until it clears the front bulkhead support.
  10. Tilt the drum toward you at a 30-degree angle while continuing to lift.
  11. Guide the rear shaft (the 1-inch diameter metal axle extending from the drum’s back center) out of its rubber bearing support located on the rear bulkhead.
  12. Pull the drum completely forward and out of the cabinet opening – the drum weighs approximately 15-20 pounds.
  13. Set the drum on a clean, flat surface with the door opening facing up.
  14. Look inside the now-empty drum cavity and locate the felt seal (gray fabric strip approximately 1 inch wide) running along the front bulkhead’s inner edge – verify it remains in place and undamaged.
  15. Check the rear bearing support for the white or tan plastic bearing cup – confirm it’s still mounted in the center of the rear bulkhead.

⚙️ Step 3: Inspect drum rollers for flat spots, cracks, or excessive wear

  1. Locate the two rear drum support rollers mounted on a shaft at the back of the dryer cabinet, positioned 3 inches from each side wall and 2 inches above the base.
  2. Spin each rear roller with your index finger, rotating it through a complete 360-degree revolution while watching the outer rubber surface.
  3. Look for flat spots on the roller surface—these appear as areas where the round profile has a straight edge, typically 1/4 inch to 1 inch wide.
  4. Run your fingertip along the entire circumference of each roller’s rubber surface, feeling for any irregularities, bumps, or indentations deeper than 1/16 inch.
  5. Examine the black rubber coating for cracks, which appear as thin dark lines that may extend from the roller’s edge toward the center shaft.
  6. Check if the rubber coating has separated from the white plastic core underneath by pressing on the rubber—movement between layers exceeding 1/8 inch indicates failure.
  7. Move to the front drum support rollers, located at the front base of the dryer, 4 inches from each side wall and directly below the dryer door opening.
  8. Repeat the spinning test on both front rollers, rotating each through a full revolution.
  9. Inspect the front roller shafts (the metal pins the rollers spin on) for rust, scoring, or material buildup.
  10. Measure the roller diameter with a tape measure or caliper—new rollers measure approximately 2 inches in diameter; replace if worn down to 1-3/4 inches or less.
  11. Listen while spinning each roller—squeaking, grinding, or scraping sounds indicate bearing failure inside the roller assembly.
  12. Check that each roller spins freely for at least 3-5 complete revolutions after a single firm spin with your finger; immediate stopping indicates seized bearings requiring replacement.

🔍

🔩 Step 4: Check roller bearings for smooth rotation – replace if rough or seized

  1. Locate the drum support rollers – there are 2 rollers positioned at the rear of the dryer, one on each side, mounted to the rear bulkhead approximately 4 inches from the bottom edge and 3 inches from each side edge.
  2. Grip the first roller wheel with your fingers and attempt to spin it by hand – it should rotate freely with minimal resistance and no wobbling.
  3. While spinning the roller, listen for grinding, squealing, or scraping sounds which indicate worn bearings requiring replacement.
  4. Check for side-to-side play by pushing the roller left and right on its shaft – movement exceeding 1/16 inch indicates worn bearings.
  5. Inspect the roller wheel surface for flat spots, cracks, or grooves deeper than 1/32 inch which require roller replacement.
  6. Repeat steps 2-5 on the second rear roller.
  7. If either roller fails these checks, use a 5/16-inch socket wrench to remove the single hex-head bolt securing the roller assembly to the rear bulkhead (turn counterclockwise).
  8. Pull the roller assembly straight off the mounting stud – the tri-ring retainer will slide off with it.
  9. Note the orientation of the tri-ring retainer (the three prongs face toward the bulkhead) for correct reinstallation.
  10. Install the new roller assembly (LG part number 4581EL2002C for rear rollers) by sliding it onto the mounting stud with the tri-ring retainer prongs facing the bulkhead.
  11. Thread the 5/16-inch hex bolt through the roller shaft and into the bulkhead, tightening to finger-tight plus one-quarter turn (approximately 50-60 inch-pounds).
  12. Spin the newly installed roller to verify smooth rotation with no binding – it should complete 3-4 full rotations from a single spin.
  13. Repeat steps 7-12 for the second roller if replacement is needed.

🔄

đź“‹ Step 5: Remove old rollers by unscrewing mounting brackets

  1. Locate the rear drum support roller assembly positioned at the back center of the dryer cabinet, approximately 3 inches from the rear wall and centered between the left and right sides.
  2. Identify the tri-star shaped roller bracket held by two hex-head screws (5/16-inch, 8mm socket size) positioned at the 10 o’clock and 2 o’clock positions on the mounting plate.
  3. Insert your 8mm socket wrench or nut driver onto the first hex screw and rotate counterclockwise 8-10 full turns until the screw releases completely from the threaded hole.
  4. Place the removed screw in a container immediately to prevent loss in the dryer cabinet.
  5. Remove the second hex screw using the same 8mm socket, rotating counterclockwise 8-10 turns.
  6. Grasp the entire roller bracket assembly with both hands and pull straight down and toward you—the bracket will separate from the mounting surface with moderate resistance.
  7. Examine the roller wheel itself, which should be gray or black rubber, approximately 2 inches in diameter, mounted on a metal shaft through the center of the tri-star bracket.
  8. Move to the front roller assemblies located at the bottom front corners of the drum cavity, positioned 4-5 inches from each side edge and 2 inches from the front edge.
  9. Use your 8mm socket to remove the single hex screw securing each front roller bracket, rotating counterclockwise 6-8 turns per screw.
  10. Pull each front roller assembly straight down and away from its mounting surface—both assemblies are identical and interchangeable.
  11. Set all three roller assemblies (one rear, two front) on your work surface with the worn surfaces visible for comparison with the new replacement rollers (part numbers 4581EL3001E for rear, 4581EL3001A for front).
  12. Verify the roller bracket screw holes show no stripped threads or damage—threads should appear clean and spiral uniformly into the mounting plate.

âś… Step 6: Install new drum rollers (replace in sets for even wear)

  1. Locate the two rear roller shafts protruding from the rear bulkhead, positioned approximately 4 inches from the center line on each side, at the bottom rear of the drum opening.
  2. Slide the first new drum roller (part number 4581EL3001E) onto the left rear shaft with the rubber tire facing outward and the white plastic hub facing the bulkhead.
  3. Push the roller firmly onto the shaft until it seats completely against the bulkhead – you’ll feel it bottom out with approximately 1/8 inch of shaft still visible beyond the roller.
  4. Repeat substeps 2-3 for the right rear roller.
  5. Spin each roller with your fingers – they should rotate smoothly without wobbling or grinding sounds.
  6. Locate the roller support brackets on each side of the cabinet base, positioned 8 inches from the front and 3 inches from each side wall.
  7. Insert the threaded shaft end of the first front drum roller assembly (part number 4581EL3002C) through the mounting hole in the left bracket from the inside, with the roller positioned to face the drum.
  8. Thread the tri-wing nut onto the shaft from the outside of the bracket, turning clockwise by hand until finger-tight.
  9. Use a 10mm socket wrench to tighten the tri-wing nut an additional 1/4 turn – the roller should spin freely but have no side-to-side play exceeding 1/16 inch.
  10. Repeat substeps 7-9 for the right front roller.
  11. Manually rotate all four rollers simultaneously – they should all turn without resistance, binding, or noise.
  12. Press down on each roller with moderate thumb pressure – none should deflect more than 1/8 inch downward, confirming proper mounting tension.

🔍

🔍 Step 7: Inspect and adjust drive belt tension

  1. Locate the drive belt wrapped around the drum – it’s a ribbed rubber belt approximately 92 inches long and 1/4 inch wide (LG part number 4400EL2001A).
  2. Press down on the belt at the midpoint between the motor pulley and the idler pulley with your index finger using 5 pounds of pressure (enough to compress the belt without straining).
  3. Measure the deflection – the belt should move downward between 1/4 inch and 3/8 inch. Less than 1/4 inch indicates too much tension; more than 3/8 inch means insufficient tension.
  4. If tension adjustment is needed, locate the idler pulley assembly on the right side of the blower housing, approximately 8 inches from the front of the drum.
  5. Use a 10mm socket wrench to loosen (turn counterclockwise 3-4 full turns) the single bolt securing the idler pulley bracket – do not remove the bolt completely.
  6. For insufficient tension, pull the idler pulley bracket away from the drum until you achieve 1/4 to 3/8 inch deflection when pressing the belt.
  7. For excessive tension, push the idler pulley bracket toward the drum to reduce belt tightness.
  8. Hold the bracket in position with one hand while tightening the 10mm bolt clockwise until snug, then apply an additional 1/4 turn.
  9. Recheck belt deflection by pressing at the midpoint again – readjust if necessary by repeating steps 5-8.
  10. Inspect the belt surface for glazing (shiny, hardened appearance), cracking, fraying, or missing ribs – any of these conditions require belt replacement rather than adjustment.
  11. Verify the belt sits centered on all pulleys without riding up on edges or rubbing against metal surfaces.
  12. Rotate the drum manually two complete revolutions clockwise while watching the belt track smoothly without slipping or squealing sounds.

đź’ˇ Step 8: Check idler pulley for wear and replace if necessary

  1. Locate the idler pulley assembly positioned at the bottom right side of the drum, approximately 4 inches from the front edge and 3 inches from the right panel.
  2. Spin the idler pulley wheel clockwise with your index finger while it remains mounted on its bracket.
  3. Listen for grinding, squeaking, or scraping sounds that indicate worn bearings.
  4. Check for side-to-side movement by grasping the pulley wheel and attempting to wiggle it perpendicular to its rotation axis—acceptable movement is less than 1/16 inch.
  5. Inspect the pulley wheel surface for a smooth, shiny groove—any visible grooves deeper than 1/32 inch, flat spots, or rough patches indicate replacement is needed.
  6. If replacement is required, use a 10mm socket wrench to remove the single hex bolt securing the idler pulley bracket to the base frame.
  7. Note the spring tension arm extends from the bracket toward the motor pulley—pull the spring hook end away from its anchor point on the base using needle-nose pliers.
  8. Lift the entire idler pulley assembly (bracket, pulley wheel, and spring) away from the dryer base.
  9. Remove the idler pulley wheel from the bracket by extracting the center shaft bolt with a 10mm socket wrench—the LG replacement part number is 4581EL2002C.
  10. Slide the new idler pulley wheel onto the bracket shaft with the grooved side facing outward, toward where the belt will sit.
  11. Thread the shaft bolt through the pulley wheel center and tighten to 8-10 ft-lbs using a torque wrench.
  12. Position the idler assembly back onto its mounting location, aligning the mounting hole with the threaded insert in the base frame.
  13. Thread the mounting bolt finger-tight, leaving it loose for belt installation in the next step.
  14. Spin the new pulley—it should rotate smoothly with zero noise and minimal resistance.

⚡ Step 9: Reinstall drum and belt, ensuring proper alignment

  1. Hold the drum at a 30-degree angle with the front edge tilted upward and position it so the rear bearing housing (the 2-inch diameter circular recess at the back center of the drum) aligns with the support shaft protruding from the rear bulkhead.
  2. Slide the drum rearward until the bearing housing fully seats onto the support shaft—you’ll feel it drop approximately 1/4 inch when properly seated.
  3. Reach underneath the front of the drum and locate the two motor pulley wheels (approximately 3 inches in diameter, positioned side-by-side) directly below the front drum opening.
  4. Wrap the belt around the drum in a clockwise direction when viewed from the front, with the ribbed side of the belt facing toward the drum surface.
  5. Pull the loose end of the belt downward and loop it around both motor pulleys simultaneously in a figure-8 pattern—the belt wraps around the left idler pulley first, then crosses to wrap around the right motor pulley.
  6. Rotate the drum clockwise by hand 3-4 complete revolutions while watching the belt track—the belt should remain centered on the drum without shifting toward either edge.
  7. Lower the front edge of the drum so it rests horizontally and verify the front drum rim sits flush against the white plastic front glides (located at 10 o’clock and 2 o’clock positions on the front bulkhead).
  8. Push down on the top-front of the drum with 10-15 pounds of pressure and rotate it another 2 full revolutions—the belt tension should feel consistent without any slipping or binding.
  9. Visually inspect the belt tracking one final time, confirming it runs centered on both the drum surface and motor pulleys with no visible twisting or misalignment.

🎯 Step 10: Test dryer operation – should run quietly without thumping

  1. Push the dryer back into its original position, leaving 4-6 inches of clearance from the rear wall for proper airflow.
  2. Plug the power cord into the 240V outlet, ensuring the plug seats completely with all three or four prongs fully inserted.
  3. Turn on the gas supply valve (if gas model) by rotating the handle counterclockwise until it aligns with the pipe direction.
  4. Open the dryer door and place 3-4 dry bath towels inside the drum to simulate a normal load weight of approximately 8-10 pounds.
  5. Close the door firmly until you hear the latch click.
  6. Press the POWER button on the control panel – the display will illuminate showing default settings.
  7. Select the “AIR DRY” or “AIR FLUFF” cycle by rotating the cycle selector knob clockwise two positions.
  8. Press the START/PAUSE button – the drum should begin rotating within 2-3 seconds.
  9. Stand directly in front of the dryer and listen for 30 seconds – you should hear only a smooth humming motor sound without any thumping, squealing, or grinding noises.
  10. Open the door mid-cycle (drum will stop immediately), then close it and press START/PAUSE again – the drum should resume rotation smoothly.
  11. Let the dryer run for a complete 5-minute cycle while monitoring for abnormal sounds or vibrations.
  12. Place your hand on the top front panel during operation – you should feel minimal vibration, similar to a refrigerator’s compressor hum.
  13. Press POWER to turn off the unit after the test cycle completes.
  14. Open the door and spin the drum manually by hand in both directions – it should rotate freely with slight resistance and complete at least one full revolution before stopping.
