Understanding the Problem
The dryer drum (drive) belt wraps around the drum and connects to the motor so the drum can rotate. When the belt becomes frayed, stretched, glazed, or breaks outright, the drum will not spin while the motor runs (or it will spin intermittently). Below are clear diagnostic and repair steps you can follow to confirm the belt is the problem and replace it. 1) Confirm the symptom: - Unplug the dryer and run a short cycle with the drum empty. If you hear the motor run but the drum does not turn (or only turns when you help it), the belt is the first suspect. 2) Visual inspection: - Unplug the dryer, pull it away from the wall, and access the drum (for many LG models this is done by removing the lint filter, then removing the top/front panel — check your manual for panel removal). Look under or around the drum for a broken or loose belt. - If the belt is snapped or hanging, that confirms the belt needs replacement. 3) Check related components (do these before installing a new belt): - Idler pulley: Spin it by hand; it should turn freely without grinding. A seized/rough idler can kill a new belt quickly. - Drum rollers (or gliders): Inspect for flat spots, excessive play or rough bearings. - Motor shaft: Check for excessive play or damaged shaft where the belt rides. 4) Purchase the correct replacement belt: - For model DLE5977W confirm the exact OEM or aftermarket part number with the model tag (usually on the dryer frame behind the door or on the rear panel) or a reputable parts supplier. Many sellers list “drum/drive belt” for DLE-series dryers — make sure the listing specifically includes DLE5977W. 5) Tools required: - Nut driver or screwdriver set (usually Phillips and 1/4" or 5/16" socket), needle‑nose pliers, work gloves, flashlight, and a flat surface to rest removed panels. 6) Removal and replacement (generalized steps applicable to many front‑load DLE series dryers): a) Unplug the dryer and move it out from the wall. b) Disconnect the vent if needed and remove the lint filter and any screws securing the top panel. Lift or slide the top panel off according to your model’s procedure. c) Remove the front panel (this usually involves removing door screws or clips). Support the panel as you disconnect any door switch harnesses. d) Reach inside and rotate the drum to locate the belt. If it’s broken, remove the belt remnants from around the drum and motor pulley. e) Inspect idler pulley and drum rollers and replace any that show wear. f) Install the new belt: feed the belt under the drum and align the ribs into the drum grooves. Wrap the belt around the motor pulley and through the idler so the belt has proper tension (idler provides tension). Make sure the belt ribs face the drum where required (follow pictorial guides from parts retailer if needed). g) Rotate the drum by hand a few turns to confirm the belt tracks correctly and that there is proper tension without binding. h) Reassemble the front panel and top, reconnect any door switch harnesses, reconnect the vent, push the dryer back into position, plug it in and run a test cycle. 7) Final test: - Run the dryer empty through a short cycle and watch/hear. The drum should turn smoothly without slipping, squealing, or stopping. Safety note: Always unplug the dryer before doing any internal inspection or repairs. If you are unsure about working near electrical components or reassembling panels, consider hiring a qualified technician.

Helpful Repair Tip
If the motor runs but the drum won't turn, press on the drum while the motor is running (briefly). If the drum turns with pressure, the belt is almost certainly broken or severely stretched; if it still won't budge, check the idler and drum rollers for seizure.
Frequently Asked Questions
Can I replace the dryer belt myself?
Yes. Replacing the belt is a common DIY repair if you are comfortable unplugging the unit, removing a few panels, and routing the new belt. Allow 45–90 minutes. If you find damaged rollers, idler or motor issues, or if you’re uncomfortable with the disassembly, hire a technician.
How much will the belt replacement cost?
A replacement drum belt typically costs $15–$40. If you need to replace the idler pulley or rollers, add another $10–$60 per part. Labor from a technician usually runs $80–$200 depending on local rates.
