Can someone tell me why my icemaker is raising the on/off lever to off after it dumps a tray of ice and to get it to work again I have to manually push it back to the on position. It worked fine until I had to unplug the fridge to un-thaw the self defrost drain hole. Is the timer on the icemaker out of cycle since I unplugged it or what? What do I need to do to resolve my problem? Thanks
