How hard is it to change out this wiring harness? Do you have any directions to help with this? Do you think this will solve a problem of no power to freezer door ice, water and light?
Answer Hi Brad. I would use a volt/ohm meter part # TJMA-DM1 to assist. you in your diagnosis. I would first remove the upper freezer door hinge cover. Look at the wire connector and see if all connections are clean and tight. If they are burnt open, then jump them. You need to see if 120 vac is at the blk. and wht. wire at both the top hinge connector and the fountain control board part # 2220396W white. If you have it here then go further to the door light switch part # 4387911. Jump these out and see if the dispenser/light and control works now. Let me know how all this comes about and we will help further. Thank You.
