How to Replace the Drive Belt on a KitchenAid Dryer
The drive belt on a KitchenAid dryer is a thin, flat, multi-ribbed belt that wraps around the entire drum circumference, then routes under a spring-loaded idler pulley and around the motor pulley. When the belt breaks, the motor runs (you can hear it humming) but the drum does not turn. This is identical to the belt system on Whirlpool dryers — same routing, same belt specifications.
Belt replacement is one of the most common dryer repairs and is straightforward once you understand the routing pattern. The belt is inexpensive ($10-20) and the repair takes about 30 minutes.
Before You Start
- Tools needed: Phillips #2 screwdriver, 1/4-inch hex nut driver, putty knife
- Parts needed: Dryer drum belt — model-specific (~$10-20). Measure old belt length or use model number.
- Time required: 25-35 minutes
- Difficulty: Intermediate
- Safety warning: Unplug the dryer. For gas models, shut off gas supply. The idler pulley spring is under tension — control it carefully.

Step-by-Step Instructions
Step 1: Remove the Top and Front Panels
Release the top panel spring clips with a putty knife (2 inches from each front corner, push inward). Lift the top panel. Remove the two screws at the top of the front panel (1/4-inch hex). Support the heavy stainless KitchenAid front panel as you disconnect the door switch wire and lift the panel up and off its lower tabs.
Step 2: Note the Old Belt Routing
If the belt is not broken (just worn/glazed), photograph its routing around the idler and motor pulleys before removal. If broken, the routing is: flat side of belt against the drum surface, wraps completely around the drum, then the belt goes down to the bottom of the machine, loops around the idler pulley (goes under the idler making an S-pattern), then around the motor pulley.
Step 3: Remove the Drum
Reach under the drum to the belt area. Push the idler pulley toward the motor to release belt tension, then slip the belt off the motor and idler pulleys. Lift the drum straight out through the front opening. Set it on a blanket to avoid scratching.
Step 4: Inspect Rollers and Glides
With the drum out, check the rear drum rollers — spin each one. They should roll freely and smoothly. If they are flat-spotted or seized, replace them now (you have access). Check the front drum glides (felt pads or plastic strips where the drum rides against the front bulkhead). Replace if worn.
Step 5: Install the New Belt on the Drum
Lay the new belt around the drum with the ribbed (grooved) side facing the drum surface. Position it in the center of the drum (there are usually wear marks showing where the old belt sat). The belt should fit in the same track.
Step 6: Lower the Drum Into Position
Lift the drum and lower it back into the cabinet. Seat the rear of the drum on the rear rollers. Reach underneath and route the belt down to the idler and motor: loop the belt around the idler pulley making the S-pattern (belt goes on the outer/right side of the idler, wraps under, exits left toward the motor). Then loop around the motor pulley.
Push the idler away from the motor (stretching the spring) to create enough slack to seat the belt on both pulleys. Release the idler slowly — the spring tension should take up belt slack.
Step 7: Reassemble and Test
Reinstall the front panel (hook bottom tabs first, then secure top screws). Reconnect door switch wire. Close the top panel (push until clips snap). Plug in and run a timed dry cycle. The drum should rotate smoothly. If it squeals, the belt may not be centered on the drum — open and adjust.
Troubleshooting
- Drum turns once then stops: belt is off the idler or motor pulley. Recheck routing.
- Belt squeals: may not be centered on drum, or idler pulley bearing is dry. Reposition belt; lubricate or replace idler.
- Motor hums but drum won't turn (with new belt): the idler spring may be disconnected or the motor pulley is stripped.
Safety First — Know the Risks
Gas dryers carry carbon monoxide and explosion risk. Even electric dryers involve 240V circuits that can deliver a fatal shock. Our techs are licensed and insured — let them handle the risk.

When to Call a Professional
- If the rear drum rollers are seized and will not come off their shafts for replacement
- If the motor pulley is stripped (motor replacement needed)
- If the idler arm is bent or broken and a new one is not readily available

FAQ
Q: Is the KitchenAid dryer belt the same as Whirlpool? A: Yes — same belt specification for the same model generation. Use your model number to find the exact belt part number.
Q: How do I know the belt is broken versus the motor? A: If you hear the motor humming when you start the dryer but the drum does not turn, the belt is broken. If you hear nothing at all, the motor or start switch may be the issue.
Q: How long should a KitchenAid dryer belt last? A: 8-12 years under normal use. Overloading accelerates belt wear.
Q: Should I replace the rollers when I replace the belt? A: Check them — if they spin freely and are round, they are fine. If flat-spotted, squeaky, or seized, replace while you have access. It saves a future teardown.
