Jusjuli,

I take for granted you have a meter to run more tests ?

Do you have the wiring diagram for the unit ?

You want to set the timer in a timed dry setting and check the terminals for a closed circuit

Check Blue to Black terminals on the timer(wires off).
Check Tan to White terminals on the timer(wires off).

*** Be CAREFUL, this is a live voltage test ***

If those circuits check OK, and you're sure the thermal fuse is a closed circuit, you'll need to check for 120 Volts AC on the blue wire on terminal #4 on the motor.

If you have the voltage, you'd have a bad motor.
Or a broken White wire from the motor to the timer.

If you have no voltage, You've got a broken blue wire from the start switch to the motor.

Hope this helps,

:) :) :)
