The in door dispensor unit in this side-by-side refrigerator is working fine for water and the ice maker and auger are working also. The problem is the solenoid does not seem to be getting any power. I have replaced the solenoid and determined this to be the case. So, the flap that opens and closes when attempting to dispense ice does not work like it should. The ice builds up in the chute and can only be accessed by opening the flap by hand. I do not own a volt/ohm meter so what part would I replace next?
