My drier works fine, although it will not shut off no matter how many mins. I set it for, it will not start if the timer is set to zero.
It will however shut off if I manually turn the timer to zero.
Any Ideas?

Thanks
Bob

Here are your parts includes a wiring diagram.

Does the timer advance?

Try it in both timed dry and auto modes.
The timer motor gets it's power through different circuits in each mode.
Direct from the line when in timed dry.
Through the heating coil when it is shut off by the thermostat when in auto.

If it does not advance in timed dry then odds are high that the timer is toast.
This can be checked by checking if it gets power (120 volts).
If it does and does not advance then the timer needs replacing.

Be very careful when checking this as there is 240 volts at the timer and that is lethal.

If it does advance in timed dry but not auto then check the heating coil and the 4,400 ohm resistor in the timer motor circuit.

Thanks for the help, the timer does not advance in either timed or auto mode.
My wife just told me the cloths also seem hotter than normal, could that be maybe a temp sensor?

Thanks

the timer does not advance in either timed or auto mode.
Since it does not advance in timed dry odds are the timer is toast as it's motor gets power directly from the line in this mode.
When it is running the circuit path is from Neutral thru the motors centrifugal switch to X/TM timer contacts, thru the motor the thru C/B timer contacts to L1 (120 volts).
This can be checked by measuring the voltage across the timer motor (TM to C on the timer) when it is running in timed dry mode. If it has 120 volts and the timer does not advance the timer is toast.
Be very careful if you do this as there is 240 volts at the timer and that is lethal!!!

It could be but is unlikely.
More likely is that your vent system needs cleaning.
