Wife reported ice dispenser suddenly quit with burning electrical insulation smell. After trying to empty the ice bucket and finding a big chunk stuck in the mechanism, I assumed the motor had burned out. Bought a replacement and installed with no change in symptoms. I then referenced the technical specs and repair forums. Checked rocker switches for continuity. Not seeing any other active components, I ordered a circuit control board from you. Installed same and again no change(i.e., no ice dispensed).

I then attempted to trace the wiring harness from the control unit to the motor. The first thing I noted is that the wire color and the number of wires going to the motor do not agree with the model's schematic or documentation. I checked every wire leading from the control board/rocker switches with the motor cable end for continuity--no hits. Leads me to believe that there is an active component somewhere in between the motor and the control board. The motor runs on 110 volts DC and there has to be a rectifier somewhere. There is one built into the motor, but as there are only two wires connected to the motor itself, they would have to be the 110 Volt DC inputs. So the DC polarity shifter and the rectifier have to be on the other end of the motor harness and I can't locate the other end. If it is behind the freezer door shell, I can't figure out how to get to it. Even if they routed all the wires back to the freezer control unit, there is likely to be a wire that has burned through somewhere behind the door shell, given the electrical smell my wife reported.

This is longer than your usual threads, but I wanted to communicate all the typical checks I have already performed. If you have gotten this far, please check my logic for flaws, point me to accurate documentation if possible, and any suggestions you might have. Personally, I'm stumped.

Could it be because it is marketed under the IKEA brand but manufactured by Whirlpool. I have searched on the unit and in the user instruction manual and both say the model number is ID3CHEXWS01. I have a picture, but don't know how to attach it to this message.
Thanks for your reply.

Thanks, Gene. Better info than I have gotten anywhere else. Part #'s, motor: 232580 Control board: 62508501. Think those are both Whirlpool numbers. On control board, I matched all numbers on the board with the old board.
If all the power for the motors come from the same source and the rest of the motors are functioning, then can we rule out the power source as the problem? My wife continues to maintain that the electrical smell came primarily from the freezer door area (tend to believe her since if her sense of smell was any better I could use her for hunting.
I will wait for your reply, but if the part no's check out, seems like the best hypothesis is a burned wire in the wiring harness in the door. If so, I would need the pinout's on the wiring harness feeding the door. I guess a more cogent question would be "can you even get into the freezer door shell?"

Thanks again for your help.
