If your Frigidaire dryer produces a hum or a buzz type noise and will not start you more than likely have a failing motor.

Here is a quick way to hopefully get you up and running for a few more cycles. This has worked for me on numerous occasion and has saved my customers countless amounts of money. Frigidaire states the motor should be replaced on dryers with this issue.

This may take two people to accomplish, start by opening the door,depress the door switch and turn the drum manually,at the same time the drum is in motion press the start button, did the drum take off? If so you have a bad motor there is a stall spot on the inside of your motor. If this did not work, you will need to disassemble the dryer gaining access to test for correct voltage to start winding of the motor.

The motor should get 110v to the winding to fire up. If you have the correct supply voltage verified with a volt meter then replace the motor.

There are several factors that could cause a dryer to not tumble.
Here are several possibilities.

-Thermal fuse is bad
-Bad power to the dryer
-Dryer belt is broken
-Start switch is bad

To make accurate test some times a volt meter is worth having,if you plan to to repair many more appliances it may be worth investing in a cheap one from a local hardware store. Dryers especially are relatively simple to test using a meter.

When the fuse reads open it will stop supply voltage from reaching the motor. This fuse will usually fail when a overheat condition occurs. If you have found the dryer thermal fuse open investigate why the fuse has tripped.

Bad power to the unit will stop the drum from turning,with a volt meter ensure the washer has proper supply voltage.

Determining if the belt is broken is fairly simple open the top of the dryer and peek in. If there is not belt around the drum you found the issue.

When you press start and hear nothing you have a voltage or start switch issue. Like stated previously the thermal fuse will take the voltage to the motor out of the equation. By using the multimeter ohm setting you can ohm the start switch out and ensure there is some resistance.
If you hear the motor running and the drum is not turning the belt is broken.
