Step-by-step fix
Step 1: Confirm the belt is the likely problem
- Unplug the dryer before touching any panels or internal parts.
- Open the door and try turning the drum by hand. A drum that spins very freely with little resistance often points to a broken belt.
- Start the diagnosis only if the dryer previously ran but the drum stopped tumbling, or if you heard a snap or thump before it quit turning.
- If your dryer has an access panel or top you can safely open, look for a broken belt, a belt lying loose under the drum, or belt dust around the motor area.
If it works: You have a strong reason to believe the dryer drive belt has failed and replacement makes sense.
If it doesn’t: If the drum is jammed, scraping badly, or hard to turn by hand, check for seized rollers, a bad idler pulley, or an object stuck in the drum path before replacing the belt.
Stop if:- You smell burning insulation, see melted wiring, or find damaged electrical connectors.
- The drum support, motor mount, or cabinet frame is cracked or badly bent.
- You cannot safely access the cabinet without forcing parts or damaging the dryer.
Step 2: Open the dryer and get the drum ready to remove
- Pull the dryer away from the wall enough to work comfortably.
- Remove the lint screen if it sits in the top panel, then remove any screws that secure the top or front panel.
- Release clips or remove screws to lift the top and remove the front panel or front bulkhead, depending on how your dryer is built.
- Take a quick photo of the drum, belt position, and any wire connections you disconnect so reassembly is easier.
- Support the drum as you remove the front support panel so it does not drop suddenly.
If it works: The cabinet is open and the drum is exposed so you can remove the old belt.
If it doesn’t: If the front or top panel will not come free, look again for hidden screws near the lint screen housing, door opening, or lower access area.
Stop if:- A panel is stuck because of rust, stripped fasteners, or hidden damage that could break if forced.
- You must disconnect wiring but cannot clearly identify where it reconnects.
Step 3: Remove the old belt and lift out the drum
- If any part of the old belt is still around the drum, note its position before removing it. The belt usually rides in a worn track around the drum.
- Reach under the drum and release tension from the idler pulley so the belt comes off the motor pulley.
- Slip the belt free, then use the belt as a handle only if it is still intact enough to help lift the drum.
- Lift the drum straight out of the cabinet and set it down carefully.
- Vacuum out loose lint while the drum is out so the pulleys and motor area stay easier to inspect.
If it works: The old belt is removed and the drum is out of the dryer.
If it doesn’t: If the drum will not lift out, check for a rear bearing, glides, or support tabs still engaged and lift it evenly instead of prying.
Stop if:- The idler pulley is seized, badly worn, or wobbling on its shaft.
- The motor pulley is loose or damaged.
- You find heavy scoring, broken drum supports, or other failed parts that would quickly ruin a new belt.
Step 4: Install the new belt on the drum
- Wrap the new dryer drive belt around the drum in the same general location as the old one, usually in the existing wear mark.
- Make sure the belt is not twisted and sits flat against the drum all the way around.
- Lower the drum back into the cabinet, seating it on the rear support or bearing surface as it was before.
- Keep the belt positioned so you can reach it from below and route it around the pulleys.
If it works: The new belt is on the drum and the drum is back in place correctly.
If it doesn’t: If the belt seems too loose, too tight, or too wide for the drum track, recheck the replacement part before going further.
Stop if:- The new belt does not match the old belt closely enough in profile or length to install properly.
Step 5: Route the belt around the motor and idler pulley
- Reach under the drum and loop the belt around the motor pulley.
- Pull the idler pulley to create tension, then route the belt so the idler keeps pressure on the belt and holds it tight against the motor pulley.
- Turn the drum by hand several full rotations to help the belt center itself and confirm the belt tracks smoothly.
- Watch and feel for binding, slipping, or the belt walking out of position as the drum turns.
If it works: The belt is routed correctly, tensioned, and the drum turns smoothly by hand with normal resistance.
If it doesn’t: If the belt jumps off or the drum binds, remove the tension and reroute the belt carefully before reassembling the cabinet.
Stop if:- The idler pulley will not hold tension.
- The drum will not rotate smoothly after correct belt routing.
- The belt rubs a sharp edge or tracks out of place because of a bent bracket or damaged support.
Step 6: Reassemble the dryer and test the repair in real use
- Reinstall the front support panel, front panel, top panel, lint screen housing screws, and any wires you disconnected.
- Spin the drum by hand one more time before closing everything fully if you still have access.
- Plug the dryer back in and run a short timed cycle while watching and listening for normal startup.
- Confirm the drum tumbles, the motor sounds steady, and there is no burning rubber smell, heavy thumping, or scraping.
- Dry a small load of laundry to make sure the belt holds under normal weight and the drum keeps turning consistently.
If it works: The dryer tumbles normally through a real drying cycle and the new belt is holding as it should.
If it doesn’t: If the motor runs but the drum still does not turn, reopen the dryer and recheck the belt routing, idler pulley tension, and drum seating. If it tumbles but makes loud noise, inspect the rollers, glides, and idler pulley next.
Stop if:- The dryer trips a breaker, smells hot, or makes severe grinding or banging noises during the test.
- The new belt comes off again during testing, which usually means another support or pulley problem is present.

FAQ
How do I know the dryer drive belt is broken?
A broken belt often leaves the drum not turning even though the motor still runs. The drum may also spin very freely by hand because the belt is no longer adding tension.
Can I replace a dryer drive belt without removing the drum?
Usually no. On most dryers, you need to remove or at least lift the drum enough to get the belt around it and route it correctly around the motor and idler pulley.
Should I replace anything else while I am in there?
If the idler pulley is worn, noisy, or seized, replace it before installing the new belt. It is also smart to inspect drum rollers or glides if the dryer was noisy before the belt failed.
Why did my new belt come off right away?
The most common causes are incorrect belt routing, a twisted belt, a seized or weak idler pulley, or a drum that is not seated correctly on its supports.
Is it normal for the new belt to feel tight?
Yes. A new belt should have noticeable tension once it is routed around the motor and idler pulley. It should still let the drum turn smoothly by hand without binding.
