Customer Questions and Answers for Dryer Belt by Whirlpool

Frank, In most cases when a dryer will start with a smaller load but not a larger, this would be caused by a weak motor in which it cannot turn the heavier load. You would also want to check the rollers on the unit to ensure that there is no damage to them.

Frank, To find out if the motor is good you would test for 120 vac to the motor. If there is 120 vac to the motor then the motor would be faulty. If not then check the thermal fuse and door switch for continuity.

Hello Dave. The roller may be loose or tight, and will make noise when it is bad. Also, they get flat spots on them. Some idler pulleys do have play in them. If they are bad, they will make noise as well.

Hello Alan. The belt does not have wire in it. We do not have the exact materials it is made from. The manufacturer will have that information.

Hello Mike, This does sound like you have damage to your belt WP40111201. You may also need to replace the drum rollers WP37001042 or the idler puller WP37001287.
