Understanding the Problem
What this kit is and when to use it: The AFT-82A-634A-55 (belt-kit191) is a dryer belt kit typically used to replace a worn or broken drum belt and sometimes includes the idler pulley and drum support parts (contents vary by supplier). A failing belt kit is the most common cause when the dryer motor runs but the drum does not turn, when the drum slips, when you hear squealing, or when you smell burning rubber. Step-by-step diagnostic and repair steps: 1. Confirm the symptom: Start the dryer on a no-heat or air-fluff cycle. If the motor runs (you hear humming) but the drum does not rotate or rotates intermittently, the belt or idler is suspect. Note any squealing, grinding, or burning smell. 2. Safety first: Unplug the dryer from power. If it is a gas dryer, turn off the gas supply at the valve. Allow the dryer to cool if it was recently used. 3. Access the drum/belt area: Remove the lint screen and any screws under the lint trap. Depending on model, release the top panel (usually by removing screws at the rear or lifting clips) and remove the front panel, or open the rear access panel. Consult your model’s manual for exact panel removal steps. 4. Inspect the belt and components: Visually check the belt for breaks, fraying, glazing (shiny spots), or missing ribs. Check the idler pulley for free, smooth rotation and no play. Inspect drum rollers/glides and shaft bearings — seized rollers will wear a belt quickly. 5. Remove the old belt: Remove the belt from around the drum by sliding the drum forward (if front access) or by releasing the idler tensioner so the belt slips off the motor pulley. Note the belt routing so you can install the new one the same way. If your kit includes rollers or an idler, remove the old components. 6. Replace worn parts: Install the new idler pulley and any included rollers or glides from the kit. Lubricate only where the manufacturer recommends (most rollers are sealed bearings and do not need extra grease). Replace any blatantly damaged drum seals or glides if they are included in the kit. 7. Install the new belt: Route the new belt around the drum grooves in the same orientation as the old belt (ribs against drum). Loop the belt around the motor pulley and feed it under/through the idler so the tensioner applies proper tension. Make sure the belt sits in the drum track and is centered. 8. Reassemble and test: Reinstall the front/top/rear panels and secure all screws. Plug the dryer back in (and restore gas if applicable). Run a short cycle to confirm the drum turns smoothly and there are no unusual noises. Check that the belt does not rub against cabinet edges and that tumbling is even. 9. If it still fails: If the drum still doesn’t turn but the motor hums, the motor start capacitor, motor centrifugal switch, motor itself, or thermal fuse may be the cause. If you hear grinding, check motor bearings. Diagnose further or contact a professional. Safety note: Always disconnect power before working on the dryer. Gas dryers require shutting off the gas supply. Use gloves and eye protection, and keep fingers clear of pinch points when reassembling the belt and drum.

Helpful Repair Tip
With the dryer unplugged, rotate the drum by hand. A broken belt is obvious if the drum spins freely without resistance; a tight belt should give firm resistance and return to center. Also inspect the underside of the belt for glazing or missing ribs to confirm failure.
Frequently Asked Questions
How long does it take to replace a dryer belt kit?
For most homeowners with basic tools it takes 30–60 minutes: 10–20 minutes to open the cabinet and inspect, 10–20 minutes to remove the old belt and install new parts, and 10–20 minutes to reassemble and test. If your model requires removing the drum completely it can take longer.
Can I still run the dryer with a broken belt?
No. Running the dryer with a broken or slipping belt can overheat the motor and damage the motor or start device, and can cause additional wear to rollers and seals. Unplug the dryer and replace the belt kit before further use.
