I have an estate dryer and the push on button starts the dryer but once you release it the dryer stops. The same principle as a car battery and alternator. Would the timer be bad, or is there a fuse or???:rolleyes:

How do I by pass the button

Here is the wiring diagram

Sounds to me, that your push to start switch is OK.
It is a momentary switch and should only close when pushed.

You will notice a centrifugal switch by the motor, it switches over once the motor gets close to operating speed.
It has two purposes.
1. It removes the motor's start winding from the circuit as leaving this on will overheat the motor.
2. It provides a circuit path to keep the motor running once the push to start is released (wired in parallel)

Could be that the switch is toast, or that the motor is jammed with lint so that the switch is not being activated. There is a mechanical linkage in the motor that activates the switches.

Try cleaning the motor.
Unfortunately if the activating mechanism or the switch itself is shot you have to replace the motor.
