All 3 LEDs are lit on my circuit boards. The PWM Led is also lit when increasing the speed. BUT, the motor that turns the belt still does not work. How can I check to see if the motor is bad? Or could I have an easy fix and just not realize it? I seen on the schematics that the motor has a temperature overload switch. How do I check that? It looks to me that it is built into the motor casing. Any help?
