Dryer won't work after pressing start button

The motor starting circuit is failing. Confirm this by giving the drum a push start when it hums. Most likely, the centrifugal switch on the motor is sticking (due to lint buildup) or broken. It has a mechanical component that operates an electrical switch. Check the mechanical operation, then check the switch. Also, check that the motor electrical connector is seated completely.

Open the dryer door and slowly rotate the dryer drum in a counterclockwise (CCW) direction. Rotate the drum 2-3 revolutions and then shut the door and see if it will start. If it continues to just hum and not start could indicate a voltage issue, motor issue or a friction issue. Open the door again and locate the door switch plunger in the upper or lower corner on the hinge side of the drum opening. Hold the plunger in while someone begins rotating the drum counterclockwise. While turning the drum counter clockwise and holding the door switch plunger inwards press the start button. If it starts, there is likely a friction problem or motor problem.
What is the model number?

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.

Try this, open the dryer door and hold down the door light switch. Turn on the dryer and press start.When you hear the motor humming, turn the drum clockwise with your hand to see if it will turn. If itruns, you have a bad motor and will need to be replaced. If it doesn't turn, something is jammedinside and you will need to disassemble the unit to find the jam.
Hope this helps.

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...

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

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.

Hi, Does the dryer only hum when you push the start button?
Might be a bad motor.
Does the motor hum but, the drum doesn't turn?
Please let me know and get me a model # so I can assist you further.

May be belt broken

no problem with motor or control board. fault is with the motor capacitor only. this is often attached to the motor or near it. the value of the capacitor will be printed on it (usually about 8uf) and you should be able to source from an electrical spares shop
