Wire Harness

unplugged the unit pulled it away from the wall removed the lower panel removed the drain installed the new replacement . removed the wiring harness and replaced it with the new one replaced the panel and plugged back in

I replaced the control board first. The freezer back panel frosted up and the refrigerator warmed up again. Then I force (short option vs long) defrosted the refrigerator. However, a few days later the defrost issue came back again. Force defrost no longer worked, though likely due to a severe ice build up behind the freezer panel. I ordered the wire harness. I took off the freezer door (loosen four screws only), removed the tray rails, ice maker, thermostat housing and vent mounted on the freezer panel. The rails and the vent are a bit tricky to remove since no directions exist. I then removed the fan above the coils and then removed the wire harness. Installing the new harness is easy except that I had to modify one of the ground connections for it to mount properly. I tested the unit for 72 hours. The defrost cycle eventually kicked in (dripping onto a pan and sizzling sound). I then reinstalled all parts. No frost build up. Good to go!
