Part Details

Installation Notes

• CRITICAL SAFETY WARNING:
• This repair involves working inside the dryer cabinet with moving parts and electrical components. Always unplug the dryer and turn off the gas supply (for gas dryers) before beginning work to prevent electrical shock, accidental motor startup, and gas leaks. The dryer drum is heavy (40-60 pounds)—use caution when removing and reinstalling. If uncomfortable with this repair, hire a qualified technician.
• TOOLS REQUIRED:
• Phillips screwdriver, flathead screwdriver, putty knife or panel tool, 1/4-inch or 5/16-inch nut driver or socket set, adjustable pliers, flashlight, work gloves, helper for drum removal (recommended).
• IMPORTANT:
• This kit contains 2 rollers. Most dryers use 4 rollers total (2 rear, 2 front or middle). Order 2 kits (quantity 2) to replace all 4 rollers.
• CRITICAL BEST PRACTICE:
• Always replace all 4 drum rollers at the same time, even if only one has failed. When one roller fails, the others are near end of life and will fail soon.
• Unplug the dryer
• from the electrical outlet to ensure complete power disconnection.
• CRITICAL:
• Never work on the dryer while it's plugged in.
• For gas dryers: Turn off the gas supply
• at the shutoff valve behind the dryer (turn valve perpendicular to gas line to close).
• Move the dryer
• away from the wall to provide working space and access to the rear panel.
• Disconnect the dryer vent hose
• from the rear of the dryer by loosening the clamp with a screwdriver or pliers.
• Take multiple photos
• of the dryer interior, drum position, belt routing, and roller positions before disassembly.
• Belt routing and roller positions must be exact for proper keep going reassembly and operation.
• Remove the lint filter
• from the lint trap and set aside.
• Remove the top panel:
• Insert a putty knife between the top and front panel near the corners (approximately 3 inches from each side), push up to release the spring clips, and lift the top panel up and back. Some models have screws at the rear—remove if present. Prop the top panel open or remove completely.
• Disconnect the door switch wire connector
• (if accessible from the front) by pulling the connector apart. This prevents wire damage during front panel removal.
• Remove the front panel:
• Remove the screws securing the front panel to the dryer cabinet (typically 2-4 screws at the top corners inside the lint trap opening and 2-4 screws at the bottom corners). Carefully lift the front panel up and forward to disengage it from the cabinet. Set aside.
• Take detailed close-up photos
• of the drive belt routing around the drum, idler pulley, and motor pulley from multiple angles.
• Belt routing must be exact for proper operation.
• Support the drum
• with one hand or have a helper hold it to prevent it from falling when you release the belt tension.
• Release belt tension
• by pushing the idler pulley toward the motor to create slack in the belt, then slip the belt off the motor pulley.
• Carefully lift the front of the drum up and out
• of the dryer cabinet.
• CAUTION:
• The drum is heavy (40-60 pounds)—use proper lifting technique and get help if needed. The drum will rest on the rear rollers as you lift the front.
• Tilt the drum forward
• and pull it out through the front opening. Set it on a clean, padded surface (blanket or towels) to prevent scratches.
• Remove the drive belt
• from the drum and set aside. Inspect the belt for wear, cracks, or glazing—replace if damaged.
• Locate the drum support rollers
• in the dryer cabinet. Most LG dryers have 2 rear rollers (mounted on a bracket at the rear of the cabinet) and 2 front or middle rollers (mounted on brackets on the sides of the cabinet).
• Take detailed photos
• of each roller's mounting position, orientation, and hardware configuration before removal.
• Remove the rear rollers first:
• Locate the roller mounting nuts on the threaded shafts (typically 5/16-inch or 1/4-inch hex nuts). Use a nut driver or socket to remove the nuts. Remove the washers. Pull the roller assemblies off the mounting shafts or brackets.
• Remove the front/middle rollers:
• Locate the roller mounting nuts and remove them with a nut driver or socket. Remove washers. Pull the roller assemblies off the mounting brackets.
• Inspect all old rollers
• for wear indicators: flat spots on roller wheels, rough or seized bearings (spin the roller by hand—should rotate smoothly), cracks in roller wheels, worn or grooved roller surfaces, or excessive play in bearings. This confirms the diagnosis.
• Test each old roller bearing
• by spinning the roller by hand. Should rotate smoothly and freely with minimal resistance. Rough, grinding, or seized rotation = failed bearing. Squealing when spinning = lack of lubrication or bearing failure.
• Clean the roller mounting areas
• on the brackets, removing lint, dust, and debris that could affect new roller operation.
• Inspect the mounting brackets and shafts
• for damage, bending, or wear. Straighten or replace if damaged.
• Unpack the new AGM75510755 roller assemblies
• from the packaging (2 rollers per kit).
• Remember:
• You need 2 kits (4 rollers total) to replace all rollers.
• Compare the new rollers to the old ones
• to verify dimensions, shaft length, roller diameter, bearing type, and mounting hardware match.
• Inspect the new rollers
• for any shipping damage before installation. Spin each roller by hand—should rotate smoothly and freely.
• Install the rear rollers:
• Position the new roller assemblies on the rear mounting bracket or shafts. The roller wheel should face inward toward where the drum will sit. Install washers on the shafts (if required by your model). Thread the mounting nuts onto the shafts and tighten firmly but not excessively.
• Do not overtighten—can damage bearings or crack roller wheels. Hand-tight plus 1/4 turn is sufficient.
• Verify rear rollers are securely mounted
• with no excessive play or wobble. Spin each roller by hand to verify smooth rotation.
• Install the front/middle rollers:
• Position the new roller assemblies on the front or side mounting brackets. The roller wheel should face inward toward where the drum will sit. Install washers (if required). Thread the mounting nuts onto the shafts and tighten firmly but not excessively.
• Verify front/middle rollers are securely mounted
• and spin smoothly by hand.
• Double-check all roller positions
• against your detailed photos to ensure correct orientation and mounting.
• Reinstall the drive belt
• on the drum by looping it around the drum with the ribbed side (grooves) facing inward toward the drum surface. Position the belt approximately in the center of the drum circumference.
• Lift the drum
• and carefully maneuver it back into the dryer cabinet through the front opening.
• Heavy—use proper lifting technique and get help if needed.
• Position the rear of the drum
• so it rests on the two rear support rollers. The drum should sit centered on the rollers.
• Lower the front of the drum
• into position, ensuring it's properly aligned in the cabinet.
• Route the drive belt
• according to your detailed photos: loop it under the idler pulley, then around the motor pulley.
• Belt routing must be exact. The ribbed side should contact all pulleys.
• Pull the idler pulley
• toward the motor to create slack, slip the belt onto the motor pulley, then release the idler pulley to tension the belt.
• Verify proper belt tension
• by pressing on the belt between pulleys—should deflect approximately 1/2 inch with moderate pressure.
• Manually rotate the drum
• several complete revolutions by hand to verify smooth operation. The drum should rotate freely without binding, rubbing, or unusual resistance. Listen for any noise from the new rollers—should be quiet.
• Check that the drum sits level
• on the rollers with no tilting or wobbling.
• Reinstall the front panel
• by positioning it and engaging the bottom tabs, then installing the mounting screws at the top and bottom. Tighten firmly.
• Reconnect the door switch wire connector
• (if disconnected earlier) by pushing the connector together until it clicks.
• Lower the top panel
• back into position and push down firmly at the front corners until the spring clips engage with clicking sounds.
• Reinstall the lint filter
• in the lint trap.
• Reconnect the dryer vent hose
• to the rear of the dryer and secure with the clamp. Ensure the connection is tight with no gaps.
• Move the dryer back
• to its installation location.
• For gas dryers: Turn on the gas supply
• by turning the shutoff valve parallel to the gas line. Check for gas leaks at all connections using soapy water—bubbles indicate leaks.
• Restore electrical power
• by plugging in the dryer.
• Run a test cycle
• (air fluff or timed dry, no heat, 10 minutes, no clothes) to verify proper operation.
• Listen carefully during the test cycle
• for smooth, quiet drum rotation with no squealing, thumping, grinding, or unusual noises. New rollers should operate silently.
• Verify the drum rotates smoothly
• without hesitation, wobbling, or vibration.
• Run a second test cycle
• (normal dry cycle with heat, small load of towels) to verify full operation under load.
• Monitor the dryer
• during the loaded test cycle for smooth operation, proper tumbling action, and no unusual noises or vibration.
• If the dryer operates smoothly with quiet drum rotation, proper tumbling, and no noise or vibration
• , the repair is complete.
• Safety Notes:
• Always unplug the dryer and turn off gas supply before working inside the cabinet. The drum is heavy (40-60 pounds)—use proper lifting technique and get help. Take extensive photos of belt routing and roller positions before disassembly. Replace all 4 rollers at the same time for best results. Do not overtighten roller mounting nuts—can damage bearings. Verify smooth drum rotation by hand before closing up. Test operation thoroughly with both empty and loaded cycles. This repair requires moderate-to-advanced mechanical skills and typically takes 60-90 minutes for DIY.
