LG Washer Drive Belt Replacement - Signs & How-To

LG Washer Drive Belt Replacement — What This Part Does

On belt-driven LG washers, the drive belt transfers power from the motor to the drum or basket. The belt wraps around a small motor pulley and a large driven pulley, turning the tub so clothes wash and spin. Over time, belts stretch, crack, glaze, or break from normal wear and friction heat. When a belt fails, the motor runs but the drum doesn’t move, or the washer squeals under load. Not all LG washers use a belt. Front-load and some top-load models rely on belts, while direct-drive designs do not. Check your model’s service diagram to confirm your unit has a belt before ordering parts.

Jump to Replacement Steps

Signs It Needs Replacing

Drum or basket does not turn You can hear the motor running but the tub stays still, meaning the belt is broken or has slipped off.
Weak or no spin cycle Clothes come out soaking wet because a stretched or glazed belt can’t grip the pulleys under load.
Squealing or rubbing noise during wash A worn or misaligned belt slips on the pulleys and makes a high-pitched squeal.
Visible cracks or fraying on the belt Inspect the belt through the rear panel and look for cracks, glazing, or torn edges.
Belt lying loose or off the pulleys Vibration or loose motor mounts can let the belt ride off-center or fall completely off.
Motor runs but basket only jerks or stutters A stretched belt barely grips and slips intermittently, causing the drum to jerk instead of spin smoothly.

How to Replace It

Unplug the washer from the wall outlet and shut off both hot and cold water supply valves behind the machine.
Pull the washer away from the wall so you can access the rear panel, and remove the screws holding the back cover in place.
Locate the drive belt looped around the small motor pulley at the bottom and the large driven pulley attached to the drum or basket.
Inspect the belt for cracks, glazing, stretching, or breakage, and check that it sits centered in the pulley grooves.
If the belt is damaged, pull it off both pulleys and note the routing path before discarding the old belt.
Slip the new belt onto the small motor pulley first, then stretch it over the large driven pulley while rotating the pulley by hand to seat the belt evenly in the grooves.
Check that the driven pulley retaining nut or bolt is tight to manufacturer specifications, and verify the belt rides centered on both pulleys without wobbling.
Reinstall the rear panel, reconnect water hoses, and plug in the washer.
Run a short test cycle to confirm the drum spins smoothly and quietly without slipping or squealing.

The Part You Need

When to Call a Pro

If the new belt slips off repeatedly, squeals after installation, or the drum still won’t turn, the motor mount may be loose, the driven pulley may not be seated correctly, or another drive component like the clutch or rotor has failed. Call a tech if you find the motor mounting hardware loose and you’re not comfortable torquing fasteners to spec, or if you’re unsure whether your LG model uses a belt at all. Direct-drive models have no belt and require rotor or stator service instead.
