This is a Whirlpool built refrig with the ice maker at the top of the freezer dropping the ice into a door-mounted bucket. The water valve is good. I checked it by powering it directly with a test wire. I changed the ice maker and the emitter and receiver boards but I still only get 96 Volts going to the ice maker so it won't cycle even if I force start it with a jumper wire. Where shoud I look next?
