When you say it does not blow air is the motor running?

It does turn, if that is what you are asking.

If the drum rotates but no air is coming out in back, the blower wheel must be stripped out. It is threaded onto the motor shaft in back and is fairly easy to replace. The part is shown below and can be clicked to order thru RepairClinic. If the shaft overheated, such as will occur with a severely restricted vent, the metal stud may weld to the motor shaft making repair impossible without replacing the motor as well. Only by a physical teardown and inspection can you satisfy yourself that the old blower shaft is removable from the motor or not. As a further note, the blower shaft has a left-hand thread.

Thank you very much for the great information that you provided. Is there an instruction somewhere as to how to replace the worn blower wheel after taking the back off of the dryer? How would I locate it, etc, etc.  THANK YOU!

Thanks! So I have to get to it from the front of the dryer and not the back of it. Correct?

Yes and no. The back is where the blower is, the front is where it attaches to the motor shaft. If my guess is rght, the wheel will pull off in your hand when you take the back cover off. When you need to  install the new one, you'll have to pull the front cover off and take out the drum. Please refer to the manual I provided.

I took the bottom front panel off and I can see the blower wheel and the motor shaft. Now I need to take the blower wheel off!
The sticker in front off the motor says to hold the blower wheel stationary and turn the motor shaft clockwise.
Do I need to worry about the belt? Do I need to take the belt off?

Would you be so kind to give me your phone number to call to ask you few questions?
The blower wheel that I see does not look like the picture you sent me. It looks like a car wheel (spoke) that has a belt on it that goes around the drum and the other end of it is on the drive shaft of the motor!
Am I looking at the right thing?? I still not sure replacing this wheel would do as it only looks like it is a support for turning the drum!

PLEASE HELP! THANKS SO MUCH

Why you think your blower is loose anyway. You cannot beat them dudes off the motor. If yours was loose it would be a freak of nature

The backside of the dryer is where all this stuff is. Here is your dryer. if your dryer has a lint problem then that fuse will blow so you needs to check fer stuff like blocked vents.

Well I am confused as to how to proceed! Do I need to worry about the blower wheel??

Could a worn blower wheel prevent the dryer from blowing air??
Where do I locate the fuse, I am looking at the back of it and don't see it!

Thx

I took the fuse off. How could I test it to see if it is good or bad?

What should I do about blower wheel suggestion that mine might be worn and therefore it won't blow air!

Please help as to how I should proceed next.

Thx!

Well you probably have a bad motor. If the drum was hard to turn then replacing the wheels and Idler might make it run right , but since it has no problems like that then the motor is toast. The bearing is worn out and is allowing the rotor to pole out or bind against the stator.
