Start button starts motor, but motor will not continue to run once the start button is released.

Several different components could be preventing your dryer from continuing to run when the start button is released. The wiring diagram and other technical information for your dryer are shown in the image below. When the start (PTS or Push To Start) button is pushed, the PTS contact is closed and voltage is supplied to the drive motor. Start voltage is also sensed through the blue/black wire that is connected to the P1-5 Start Sense pin on the control board. When the control board senses the start voltage, it normally applies 48 volts DC voltage through the Pink/Black wire to the motor relay to hold the contact closed between the two blue wires attached to the motor relay that supplies normal run voltage to the drive motor. With the start button taped down, the motor continues to run since it gets voltage through the closed start button. Since the motor stops running when the start button is released, it indicates that you have one of these 3 failures:
Broken or disconnected Start Sense wire.

Failed electronic control board that is not sending the 48 volts DC voltage through the motor relay Failed motor relay. Wiring failure between the components.
Since the motor relay and the heater relay are both exactly the same part, you could unplug the dryer and switch the motor and heater relay to see if the dryer will stay running. If it does, then you just need to order and replace the bad relay.

There is a centrifugal switch inside the motor that is not working. The switch breaks the start capacitor and makes to line voltage so the motor will continue to run once the start button is released

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.

If it has even heat board, that is most likely the problem or the heat relay.

Sounds like you have bad run windings on your motor. Holding the start button continues to send power to the start windings. When you release it the power should kick over to the run windings. You will need a new motor. _MJ_

No problem at all.The motor has a start and run winding.Your run winding is bad.The reason you have no heat is the run winding has to run to close the contacts on the motor switch.Replace the motor ,both problems solved. Hope this helps Please rate my response :)

Hi, If the motor only runs while the start button is pushed, the motor start winding is going bad. The motor will need replaced to fix your dryer.
Please let me know if I can assist you further.
