Dear Expert, When I went to turn on my Roper dryer it made a humming sound for a few seconds then quit, without out the dryer ever starting. I then had my wife depress the start know while I held the dryer door switch in and hand rotated the drum. The dryer hummed again then quit. I appreciate your help on this. Michael

You have a blown thermal fuse. Here is a link to the part you need.

Hello,

That sounds pretty typical of a motor that has tight bearing and shutting off due to excessive heat being created at the motor because of the tight bearings on the motor. What will usually happen whena motor is very tight is that it will run a few minutes (or cycles) and get too hot and shutoff until it cools down and will start then shutoff agian once too hot.Along with it not starting because of the friction of the tight bearing the motor will make a humming noise and may or may not start.

Hi,

There can be many reasons why your dryer will not start or turn...

The most common causes are the belt breaking or jumping off, or the motor goingbad...

It sounds like the motor was damaged in the flood. You may be able to salvage it by spraying both ends of the motor shaft with penetrating oil several times moving it in between, but you may not be able to salvage it.

Could be a couple things causing this problem. If you can turn the durm by hand without much resistance then the belt may be too loose. This could be because the spring on the tension pully came off or the belt streached. The humming you hear is the motor spinning. If you cannot turn the drum by hand then something could be stuck between the drum and the frame of the dryer.
I would also check that the dryer is wired correctly, because low voltage could be causing the motor to hum but not turn.

Sounds like thermal cut off fuse has blown. That is indicative of airflow obstruction somewhere either internally in the dryer or venting from dryer to outside v

I have fixed quite a few dryers and from what you say it sounds exactly like the motor is shot.

Roper RGV4634KQ1 gas Dryer Starts to dry, turns 2-3 seconds, stops turning and makes loud screeching sound. Turn off to stop noise. Retry same situation.
