This Kitchenaid Ref w/ Whirlpool Ice Mkr was working fine. Just stopped. Call for tech support and get brick wall of assistance from nice folks there. I have not been able to get my hands on a wiring diagram. 1st Source has none. Cant find one on machine. There is no voltage between L & N when plugged in. 120 V between blk & wht pins when unplugged. Looks to me like a bad connection somewhere in the cabinet wireing. I am about ready to punt.

Hi,
There is a thermo fuse in the black wire on the ice maker harness. If the ice maker heater gets to hot the fuse blows. You will need a new ice maker if that is the case.
Try here.
