The Fan was working properly and now it doesn’t spin. I know the fan should be good and the only few things that could cause it not to spin is the fan motor, pump or actuator solenoid. 1. Is there a way to test these parts to see which one is the malfunctioning part? 2. If the fan is fine and it’s the motor, can I remove the motor off of the fan and replace it with a new one? 3. Should I just replace all 3 components? Don’t suggest converting to electric please, working with what I have atm and converting is out of my range. Any positive help and feedback is greatly appreciated.
