Looking at the electrical schematic, when the dryer is in regular heat auto mode, the timer motor should get power through the cycling thermostat which will send power to the V terminal on the 3-position switch. The switch won’t affect this except when LI to C (regular heat) continuity is disrupted. I checked the V terminal (connected to the same orange wire as the cycling thermostat) with the dryer running (reg heat and auto) and there was no power. But I think this is the case most of the time since the cycling thermostat is probably not in the position to send power to the timer. Am I off base? If not, what next?
ANSWER Hello Chris. Yes, you tested it properly. Ok, if the motor is not getting power from the orange wire coming off the cycling thermostat, and the thermostat is new, you will need to trace and see where you are loosing the power at. The cycling thermostat has to drop the blue wire from the purple wire and send voltage to the timer motor through the orange wire. The temperature switch is testing good, according to continuity, and you have power at the blue wire. Make sure the cycling thermostat is hooked up correctly, I'm sure it is , but it does not hurt to check and see. The cycling thermostat has 5 terminals on it, and you will only use three. You will use the two large and the small one by the large terminal according to the diagram. If it is wired properly, you will need to run the unit and trace and see where you are loosing the power on the orange wire at. Hopefully this is not confusing you. Thank you and Good luck!!
