Our ice maker is making ice intermittently, perhaps making two or three trays of ice per day. Temp seems to be ok. I live in a rural area, so it would be expensive / difficult to get a repair service. I’ve replaced the icemaker WPW10122559 and cleaned the cooling coils. The led / sensor light in the ice box goes on when I open the door, but goes off if I push in the door open switch and the switch that opens the door from the ice maker to the icebox. Any suggestions?
