Dryer blower motor runs slow and makes loud humming noise.

The Start/Run Capacitor has failed. The capacitor give the motor a voltage jolt to get it going. A 'humming noise is a giveaway for that issue.

DRYER BUZZING NOISE - Dryer For Sale

If the hum is loud I would suspect something is jammed and the motor is stopped leading to a heavy current running through the motor. After 5 or 10 minutes I would anticipate the circuit breaker would trip or the motor would burn up. If the humming suddenly stops then a thermal overload switch might be activating and when it cools down normal operation resumes. This is my only insight.

Hello, dirt or a weak run capacitor will cause the motor to run slow, if the blower whell is clean then change out the capacitor.

Hi,

The motor is going bad and this will make that loud humming when it is running...

This is usually the motor but not always. Remove the belt. Check for obstructions in the blower fan housing. Manually rotate the shaft of the motor.
If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor. If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers, pulley, rear bearing, then reassemble the dryer and try it again. If the motor hums but doesn't rotate on its own even with the belt removed--yet you can turn it freely by hand--you usually need to replace the motor or the motor start capacitor.

find and replace the start capacitor. If it has none, you will need to replace the motor.

this is the motor overheating and, the overload shutting down the motor: check to see if the motor belt is binding

the humming noise is most likely your motor. does it overheat or shut down on you? do you smell anykind of burning? Joe
