Fans and Blower motors Circuit #3
I have been having problems with blowing fuse number 3 which is supposed to be a pink wire. According to the schematic I have, there are three devices that use that line. One is the water pump, the other is the furnace, and the third is the Kitchen Vent hood. I unhooked the water pump so it is not that. The furnace blower should not come on unless it is lit and running so I think it is probably the vent hood. I assume the motor is supposed to come on when you move the lever. So pushing the lever toward you or away from you is on? These are all DC brush motors I am assuming which means when the rotor is locked it is basically a dead short. When I plug in the fuse I can here a thump like a motor trying to start so I am suspecting the vent hood motor.
