GE Dryer - Confirm diagnosis for system shutting off
 
This coin operated dryer shuts off in about 10-20 seconds after a cool start. Once it shuts down it will initially start but shuts back down. If you wait a minute or two it then runs for 10-20 seconds before shutting down again. While running sometimes I hear a very brief cut out then continues a short period until it shuts down. This happens in the only 3 modes it has, high, low and permanent press. The heater heats each time. All performed without the exhaust hooked up. If you kept the press to start button held down it would continue to run.

I checked to make sure both exhaust and blower inlets were clear.

Checked line voltage.

The drum rotated smoothly in the direction it spins.

Seal between the blower and motor looked good.

The heater coils were clean (no black marks) and the connections appeared in good shape (no measurements were made).

Immediately after it ran for a period with the start button held down I checked continuity on the Safety Thermostat and the Thermal fuse, they both still had continuity. I could not check Thermostat Inlet Blue at the same time after running due lack of access, but later it had continuity as did T/st Outlet(biased) on the blower.

I believe from reading multiple postings with similar issues I need to replace the motor, WE17X10010.

But I am not overly confident.

If the system is really overheating and the Thermostat Inlet Blue or the T/st Outlet(biased) is shutting the system down due to high heat or malfunctioning, could this be the cause??

Can someone knowledgeable please confirm or point me in the right direction.

Thanks for reading this long post (just wanted to be detailed).

Since no one has replied, I went ahead and replaced the motor. The problem still exists, only it shuts down immediately cold or hot every time.

Any idea's ???????????????????????????

I am not the above but will give you what I know and perhaps it will help.

You said earlier "Immediately after it ran for a period with the start button held down" does this mean that the unit runs OK if you hold the start button down?
If yes then I would look at the belt/idler switch.
I am doing some guessing here as GE likes to keep all tech data a secret and I do not have access to it. But I did find a general wiring diagram (See below link) for a GE and it shows that the start switch is wired in parallel with the belt/idler switch which will kill power to the unit's motor.
Could be the switch itself or that the belt has a problem or the idler is bouncing around too much.
