Understanding the Problem
The drive belt on an Amana gas dryer wraps around the drum and connects to the motor pulley and idler so the drum tumbles during operation. A worn, frayed, or broken belt will stop the drum from turning even though the motor may run. Below are step-by-step diagnostic and repair instructions you can follow to replace the belt yourself. 1) Prepare and diagnose: a. Unplug the dryer from the electrical outlet. For extra safety on a gas dryer, shut off the gas supply valve at the back and keep the dryer unplugged while you work. b. Open the dryer door and try to rotate the drum by hand. If the drum spins freely or you see a broken belt hanging, the belt is the likely cause. If you hear motor noise but the drum doesn't turn, that also points to the belt or idler. c. Remove the lint screen and use a flashlight to inspect the drum edge for a belt fragment or loose belt. 2) Tools and parts you'll need: - Philips and flat-head screwdrivers - Nut driver or socket set (commonly 1/4" or 5/16") - Replacement drive belt (model-specific) - Optional: work gloves, small pry bar, putty knife 3) Access the drum and remove the old belt (common front-access method): a. Unplug and shut off gas (again). Pull the dryer away from the wall so you can access the back and sides. b. Depending on your Amana model, remove the top panel by unscrewing the rear top screws and sliding the top forward, or release the two clips at the front (use a putty knife to depress clips). Lift the top up or remove it. c. If applicable, remove the control console or flip it up and disconnect any wiring harnesses (mark them if necessary). d. Open the door and remove the screws at the top of the front panel (inside the door opening) then lift the front panel off the bottom clips or disconnect the door switch harness if present. Set the panel aside. e. Pull the drum forward enough to access the belt, idler pulley, and motor pulley. Note belt routing before removing. f. Release tension on the idler pulley and slip the belt off the motor pulley, then remove the drum from the cabinet. 4) Inspect related parts and install the new belt: a. Check the idler pulley for smooth spinning and the motor pulley for damage. Inspect drum glides/rollers for wear. Replace any worn parts now to avoid redoing the job. b. Place the new belt around the drum so the ribbed side faces the drum (ribs contact the drum grooves; smooth side faces out) — this is the typical orientation but check the belt labeling or the old belt orientation if possible. c. Position the drum back into the cabinet and route the belt under/around the idler pulley and motor pulley in the same path as the old belt. Apply tension by pulling the idler so the belt is snug against the motor pulley and idler. d. Manually rotate the drum a few turns to ensure the belt tracks correctly in the drum grooves and does not rub on the cabinet. 5) Reassemble and test: a. Reinstall the front panel and door switch harness (if disconnected), reattach the control panel/top, and reinstall any screws you removed. b. Push the dryer back into place, reconnect power and restore gas supply. c. Run a short cycle to confirm the drum tumbles smoothly without noise and there are no rubbing or slipping sounds. Safety note: Always disconnect electrical power before starting. On a gas dryer it’s recommended to shut off the gas supply as a precaution; you don't normally need to disconnect gas lines to change the belt. If you smell gas after reassembly, stop and call a qualified technician or gas utility immediately.

Helpful Repair Tip
To confirm the belt is bad: open the door and try turning the drum by hand. If the drum turns freely while the motor runs and you hear the motor humming, the belt is likely broken or slipped off. Visually inspect the belt for frays, missing ribs, or a clean break.
Frequently Asked Questions
How long does it take to replace the drive belt on an Amana dryer?
For someone with basic tools and a little mechanical skill, replacing the belt takes about 30–60 minutes. If you need to replace rollers or the idler too, plan for an hour to 90 minutes.
Can I replace the dryer belt myself, or should I call a technician?
Yes — most homeowners can replace the belt themselves with common hand tools and by following the steps above. Call a technician if you’re not comfortable cutting power/gas, if the gas hookup needs work, or if you find motor or gas-valve issues. If wear is present on rollers or the idler, consider replacing those at the same time to prevent repeat failures.
