Dryer won't stay on without the button held in

SOURCE: GE dryer starts but..... stops

What you describe is either a failed evenheat board or a failed motor relay.
Please post the complete model number from the machine and I can help you narrow it down. There should be a wiring diagram inside the console with voltage checks also.
Thanks/Mike

Door switch If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is 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.Check online for the part repairclinic.com has it for $14.00 not bad

Hi,

It sound`s to me based on your description, the start relay/switch is faulty. (the other unlikely possibility is the start switch in the motor).

If you call a local part`s supplier or check out searspartsdirect.com, apwagner, partsdepot, repairclinic etc. with your model & serial number, they should have that part for you.

Hope that help`s you. Please take a second and rate the information provided to you here at fixya.

Thanks for visiting fixya and good luck.
