Understanding the Problem
A broken or slipping drum belt is a common cause of a dryer drum that won't turn, spins intermittently, makes squealing noises, or produces a burning rubber smell. The belt wraps around the dryer drum and connects to the motor pulley through an idler (tension) pulley; when it fails the drum won’t turn even if the motor runs. 1) Confirm the symptom and initial diagnosis: - If the dryer runs (motor sounds) but the drum does not turn: very likely a broken belt. - If the drum turns but slips, or you hear squealing/rumbling: belt may be glazed/worn or idler/rollers are failing. - If you smell burning rubber: belt is likely slipping or rubbing against a hot surface — stop use immediately. 2) Gather tools and parts: - Tools: screwdriver (Phillips and flat), socket/nut drivers (commonly 1/4"–5/16"/8mm), putty knife (to release clips under top panel), needle-nose pliers, work gloves, flashlight. - Parts: replacement drum belt sized for your DG08 (measure old belt or check model tag), consider idler pulley and drum roller(s) if worn. 3) Safety first: - Unplug the dryer from the electrical outlet. For gas models also shut off the gas supply and disconnect per local code if you will move the dryer or disturb the gas line. - Work on a cool dryer; allow it to sit if recently used. 4) Access the belt and drum: - Pull the dryer away from the wall to access the back and front. - Remove the lint screen and, if applicable, the lint housing screws. - Release the top panel (many models have clips at the front — use a putty knife to depress them and lift the top). - Remove the front panel screws (or clips) and lift the front panel clear; be careful of wire harnesses for the door switch—disconnect if necessary. - Tilt the drum forward and slide it out of the cabinet. Note the direction and routing of the old belt before removing it. 5) Inspect components: - Check the belt for breaks, fraying, glazed/shiny surfaces, or missing ribs. - Spin the idler pulley and drum rollers by hand; they should spin freely without roughness or play. - Inspect drum glides/slide pads for heavy wear. 6) Replace the belt (how to fix): - Remove the old belt from around the drum and off the motor pulley and idler. - If replacing idler or rollers, remove and install those parts now following the reverse order of disassembly. - Place the new belt around the drum with the ribbed side engaging the drum grooves as the original did (most ribbed belts face the drum grooves). - Route the belt under the idler pulley and around the motor pulley so the idler provides tension. Ensure the belt sits squarely in the drum grooves and on pulleys. - Reinstall the drum into the cabinet, making sure rear lip fits into the rear drum bearing or support. - Reconnect the front panel and any door switch harness you disconnected. Replace the top and secure any screws. 7) Test before full reassembly and final check: - With the dryer still pulled out and reassembled, manually spin the drum to ensure smooth rotation and correct belt routing. - Plug in the dryer and run a short no-heat or air-only cycle to confirm the drum turns normally and there are no unusual noises. 8) Final notes and preventative tips: - If the motor hums but will not start and you replaced the belt, check the motor and start capacitor or motor thermal fuse — excessive load from a seized idler/roller can trip motor protection. - Replace idler pulley and drum rollers in sets if they show wear; replacing only the belt often results in a second failure soon after. Safety note: Always disconnect power before working on the dryer. For gas dryers, do not disconnect gas fittings yourself unless qualified; if you must move the gas dryer, turn off the gas supply and consult local codes or a pro.
Common Symptoms
Drum won’t turn although motor runs; squealing or thumping noises during spin; burning rubber smell; intermittent drum motion; visible frayed or snapped belt.
Common Causes
- Broken, frayed or glazed drum belt
- Worn or seized idler (tension) pulley or drum rollers causing extra load on belt
- Mis-routed belt or worn drum glides causing excess friction and belt damage

Helpful Repair Tip
If the motor runs but the drum doesn’t turn, try turning the drum by hand with the dryer running (briefly and with the front panel safe to touch) — if the motor is running and drum is stationary the belt is almost certainly broken. Also visually inspect the old belt for glazing or cracks to confirm age-related failure.
Frequently Asked Questions
How long does a DG08 belt replacement take?
For someone comfortable with basic appliance repair: about 30–60 minutes. First-timers should allow 60–90 minutes. Time depends on how easy it is to remove the front/top panels and whether you also replace rollers or the idler.
Should I replace the idler pulley and drum rollers when I replace the belt?
Yes — if the idler pulley or rollers show any roughness, play, or squeal, replace them at the same time. Worn pulleys or rollers increase friction and cause the new belt to wear out prematurely; a full kit is good preventive maintenance and avoids a second tear-down soon after.
