Motor humming drum stopped. pulley or belt perhaps?

If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor: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 or pulley, and 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.

Hello there:
If your dryer doesn't tumble, check these:
Belt Dryers have a drive belt that turns the clothes drum. If the belt breaks, the drum stops rotating. Then you need to replace the belt, and often the idler pulley, because the pulley tends to wear out at the same time.

Hi, If your dryer doesn't tumble,The problem might be from three different reasons,which are described below,check these:
1.BELT; Dryers have a drive belt that turns the clothes drum. If the belt breaks, the drum stops rotating. Then you need to replace the belt, and often the idler pulley, because the pulley tends to wear out at the same time.

2.MOTOR; If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor: 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 or pulley, and 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.
3.DOOR SWITCH; Your dryer can't operate at all if the door switch is defective. It's inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. If it's defective, you need to replace it.
Thanks and good luck

Sounds like the belt is slipping,
Did you hear a humming noise or any other kind of unusual noises coming from the dryer at the start up or after?
If it makes a humming noise, most likely the problem is a bad motor which has to be replaced in such a situation.
If it makes noises but not a humming one then the problem could be with the worn out drum support rollers and/or the idler pulley.

To get access to all the parts inside the dryer, remove two screws at the lint screen slot and using a putty knife, push and pry the clip on each side in front of the top panel to release the holding clips. Lift up the top panel until it rests on the hinges. Unplug the quick disconnect plug for the door switch. Remove a screw from each side of the front panel. Pull the front panel up and toward yourself to release it from the retainer clips. Looking under the drum you'll find the idler pulley with the belt. Draw a picture of the belt that goes through the idler pulley onto the motor pulley so you will know how to assemble it back. Remove the belt and pull out the drum. Now you have access to all parts inside the dryer. the parts you will see are The motor ,The belt,The drum support rollers,The idler pulley. ------ also check the lint trap in the bottom of the dryer.if any foreign object or metal object like coin or broken pen or a cloth is got jammed in the lint trap that this will stop the drum from rotating to its normal speed.you can get required parts from.www.repairclinic.com this will help.thanks.

Sounds like a weak motor. You'll have to get a new motor installed. They are fairly inexpensive and easy to install yourself on that type of machine if you are handy. Motor is located in the bottom right of the machine, attached to the drum belt through a small pulley underneath the drum next to the motor.

You probably have a broken belt - pop the top and check it. Top held down with spring clip - pry it open - bve careful of finish.

Motor malfunctions usually call for service by a professional. There are three main causes of motor failure: lack of lubrication, a defective motor switch, or worn or frozen bearings. A humming sound can be related to a burned-out motor or a defective switch. Check these trouble spots before you call a professional service person or take the motor to a repair shop. Here's how to check a dryer motor:
Step 1: Remove the back access panel. Then reach behind the drum, motor pulley, and idler arm pulley. If these areas are clogged with dirt and lint, undue strain on the motor may be causing the humming noise. Worn or broken belts can also cause a humming noise. Check the belts for wear and damage. If the belts look all right, you may be able to stop the noise by spraying them with fan belt dressing, available at automotive and hardware stores and home centers.
Step 2: Turn the dryer on. The noise you hear may be the whirl of the spinning drum, not the motor. Some noise is normal.
Step 3: Force a little 20-weight nondetergent motor oil (not all-purpose oil) around the ends of the motor shaft. This lubrication may stop the humming noise. If this doesn't solve the problem, remove the motor and take it to a professional service person.The centrifugal switch on the dryer motor may be located on top of the motor. Humming, no motor power, and no heat can be caused by a faulty centrifugal switch. If the switch is externally mounted, check the terminals of the switch to make sure they are tight and not burned. If you spot trouble, remove the switch and take it to a professional service person for testing. A faulty switch will probably have to be replaced. Some centrifugal switches are located inside the motor housing; you won't be able to remove the switch in this case. Remove the entire motor and take it to a professional for repairs.
If the motor hums, but won't run the pulley on the end of the motor shaft, try turning the pulley by hand.Caution: Before turning the pulley, make sure the power to the dryer is turned off.

If dryer does not spin it is usually a problem with the belt or the motor. Check also door switch.

• 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 or pulley, and then reassemble the dryer and try it again.
