How to Replace a Dryer Belt
To replace a dryer belt, unplug the dryer, open the cabinet, remove the old belt, wrap the new belt around the drum, route it through the idler and motor pulley, then test that the drum turns smoothly before reassembling.
A worn or broken dryer belt can leave the drum sitting still even though the dryer runs or hums. This is a manageable repair for many homeowners if you work carefully, keep track of screws, and make sure the new belt is routed the same way the old one was.
Before you start: Match the belt profile, length, and dryer compatibility before ordering.
Safety first
- Unplug the dryer before opening the cabinet or touching internal parts.
- Wear gloves because dryer cabinet edges can be sharp.
- Do not force panels, pulleys, or the belt into place; forcing parts usually means something is misaligned or the replacement is wrong.
- If you find scorched wiring, melted insulation, or structural damage inside the dryer, stop and repair that issue before running the appliance again.

Step-by-step fix
Step 1: Confirm the belt is the likely problem
- Unplug the dryer before touching the cabinet or reaching inside.
- Open the door and try turning the drum by hand. A drum that turns very easily with little resistance often points to a broken belt.
- Think about the symptom you had before opening the dryer: the motor ran but the drum did not turn, the dryer hummed, or you heard a thump and then lost drum movement.
- If you can see belt debris, a snapped belt, or a belt hanging loose around the drum area, replacement is the right next step.
If it works: The symptoms match a failed or slipping dryer belt, and you are ready to open the dryer.
If it doesn’t: If the drum is locked up, badly scraping, or hard to turn by hand, check for seized rollers, an idler problem, or an object stuck in the drum path before ordering a belt.
Stop if:
- You smell burnt wiring, see melted insulation, or find damaged electrical connectors inside the cabinet.
- The drum support, bulkhead, or motor mount looks cracked or badly bent.
Step 2: Open the dryer and expose the drum
- Pull the dryer away from the wall enough to work comfortably and disconnect the vent if it blocks access.
- Remove the lint screen if your dryer has one in the top panel, then remove any screws hidden in that area.
- Release the top panel clips with a putty knife or remove the top fasteners, depending on how your dryer is built.
- Lift the top and remove the front panel or front access panel so you can reach the drum, belt, idler pulley, and motor pulley.
- Take a quick photo before removing anything if the old belt is still partly in place.
If it works: You can clearly see the drum area and have access to the belt path.
If it doesn’t: If the cabinet does not open the way you expect, pause and look for hidden screws along the back edge, inside the door opening, or under trim pieces rather than forcing panels apart.
Stop if:
- A panel will not release and feels like it will bend or crack if forced.
- You uncover heavy lint buildup around wiring or the heater area that looks scorched and unsafe.
Step 3: Remove the old belt and inspect the moving parts
- Reach under or around the drum and release tension from the idler pulley so the old belt can come off the motor pulley.
- Slide the old belt off the drum and remove any broken pieces from the cabinet floor.
- Spin the idler pulley by hand and check that it turns freely without wobbling or grinding.
- Turn the drum support rollers by hand if visible and make sure they are not seized or badly worn.
- Vacuum out loose lint while the cabinet is open so the new belt does not ride through debris.
If it works: The old belt is out, and the pulleys and supports have had a basic condition check.
If it doesn’t: If the idler pulley or rollers are rough, noisy, or frozen, replace those worn parts too or the new belt may fail early.
Stop if:
- The motor pulley is loose, damaged, or missing part of a groove.
- The idler arm is bent, cracked, or will not hold belt tension.
Step 4: Install the new dryer belt on the drum
- Wrap the new dryer belt around the drum in the same general position as the old one, usually with the ribbed or grooved side against the drum if your old belt was installed that way.
- Center the belt in the wear mark left by the old belt if that mark is visible and even.
- Use one hand to hold the belt in place on the drum while you prepare to route it below.
- Make sure the belt is flat all the way around and not twisted.
If it works: The new belt is sitting evenly around the drum and ready to be routed through the tensioner and motor pulley.
If it doesn’t: If the belt seems obviously too loose, too short, or the profile does not match the old one, recheck fit before forcing it into place.
Stop if:
- The replacement belt does not match the old belt closely enough to route safely.
- The drum edge or belt track area is damaged enough to cut or throw the new belt.
Step 5: Route the belt around the idler and motor pulley
- Lift the drum slightly if needed and reach underneath to route the belt through the idler pulley path and around the motor pulley.
- Apply tension with the idler so the belt is snug on the drum and seated in the motor pulley groove.
- Rotate the drum by hand several full turns in the normal direction to help the belt center itself and confirm the pulleys are tracking correctly.
- Watch and feel for slipping, twisting, or the belt walking off the pulley path.
If it works: The belt stays aligned, the idler holds tension, and the drum turns smoothly by hand.
If it doesn’t: If the belt jumps, twists, or will not stay in line, remove it and reroute it carefully before reassembling the dryer.
Stop if:
- The idler cannot maintain tension on the belt.
- The drum binds, scrapes hard, or will not rotate smoothly after correct belt routing.
Step 6: Reassemble the dryer and test the repair in real use
- Reinstall the front panel and top panel, reconnect any door switch connector you unplugged, and tighten all screws securely.
- Reconnect the vent if you removed it, move the dryer back carefully, and plug the dryer in.
- Run the dryer on a short timed cycle and watch for normal startup, steady drum rotation, and no burning smell.
- Let it run for several minutes, then stop it and confirm the drum has been turning consistently and the clothes inside tumble normally if you test with a small load.
If it works: The dryer starts, the drum turns normally, and the belt holds during an actual cycle.
If it doesn’t: If the motor runs but the drum still does not turn, reopen the dryer and recheck belt routing, idler tension, and pulley condition. If the dryer will not start at all, the problem may be elsewhere.
Stop if:
- You hear sharp metal scraping, smell burning rubber, or see the belt tracking off path during the test.
- The dryer trips power or shows signs of electrical trouble after reassembly.

FAQ
How do I know the dryer belt is broken?
A broken belt often causes the motor to run while the drum does not turn. The drum may also feel unusually easy to spin by hand. In some dryers, you may find belt pieces inside the cabinet.
Can I replace a dryer belt without taking the drum out?
Sometimes, but not always. Many dryers let you lift or support the drum enough to route the belt underneath. Others are easier if the drum is partially removed. The goal is safe access, not forcing your hands into a tight space.
Should I replace anything else while I am in there?
If the idler pulley or drum rollers feel rough, noisy, or seized, it is smart to replace worn support parts at the same time. A new belt will not last long if another moving part is dragging or out of line.
Why did my new dryer belt come off right away?
The most common causes are wrong belt fit, twisted installation, incorrect routing around the idler and motor pulley, or a worn idler pulley that cannot hold tension.
Is it safe to run the dryer with a slipping belt?
No. A slipping belt can overheat, wear quickly, and leave you with the same no-tumble problem again. It is better to replace it and check the pulleys before using the dryer normally.
