When start button is pushed, hums but does not run. Drum does not turn. Belt is okay

Cam,
One thing you can check on if the circuit breaker is okay is to see if the drum turns freely. If the belt is still intact, you should have some resistance to turning the drum by hand. Many dryers have a safety in them that if the belt breaks the dryer will stop and not restart until the belt has been replaced. Hope this helps!

That is a bad sign. If the buzzing starts when you press the start button and stops when you release its almost safe to say that the motor has a dead short or grounded out and causing that to happen. You can check the start switch by getting a multimeter and with the dryer unplugged take the wires off the switch, place a lead on each pin and press the start with meter set for continuity. If it shows continuity when presed and stops when released your motor is shot and needs to be replaced.
Now if you press the start button and the machine starts to hum and continues to hum its possible that something has gotten caught in the blower wheel and binding the motor up. Depending on the make and model the location and access to it vaaries.
If you can turn the drum and then the dryer starts you have a bad motor. The way the dryer works is when you initially push the start button, electricity is sent to the start winding, or stator, of the motor. This will in turn start the motor turning. From there the stator will drop out of the electrical process and at the same time the run winding, or rotor, will take over and the motor will continie to run. Your stator is damaged, has a burn spot, etc so by you turning the drum, the belt around the drum is moved which is attached to the motor pulley. You basically take the place of the stator. Long story short, you have a bad motor.

unfortunately your motor is locked up. Try this, with the door open depress the door switch and have some one push the start button while you turn the drum by hand if it starts then you'll know the start winding on the motor is failing

If the motor continues to hum afteer letting go of the button, then it is likely a broken drum belt. If the motor hums but stops when you let go of the button, something is preventing it from turning. This could be a seized motor or a drum that is stuck, or something caught in the fan blade.

It's probably the belt that turns the drum. Remove the front panel to see if the belt is broken

Humming indicates motor is getting weak. If you look in the back compartment of your dryer you can probably see the belt. You can relieve the belt tension and then take the belt off the motor pulley. Once you do this, make sure the belt is out of the way and push the start button. If the motor turns it means it couldn't push the weight and is too weak to run. It make not turn without the belt on it either but you will hear if the sound is coming from the motor. In either case you need a new dryer or new motor if the dryer is pretty new.

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 going bad...

Here are a couple of tips that I wrote will help you to figure out why your dryer will not run...

Sounds like the belt that turns the drum has broken. the hum sound is the motor turning. Does it still get hot in the drum? If so then you need a replacement belt ($15-$25).You can open the rear or the dryer to confirm the belt is broken. Be sure to unplug from the wall outlet to avoid electrical shock.

Since your dryer is "new" it is under warranty. I will explain the possible reasons why it will not spin. Then you can decide whether to make the warranty call or not.

If your dryer doesn't tumble, check these:

Belt
Motor
Door switch
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.

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.

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.
