Hello,
I replaced the defrost heater harness on my side-by-side refri back on Oct. 10th (after getting the diagnosis from a local repair company). The refri & freezer started working great for over 1 week but today, again, the refrigerator is back up to 60 degrees. Also, there's frost build-up on the back panel of the freezer. Obviously, there's a problem with the defrost system...I read a thread & used this website's search box but the defrost timer doesn't even come up using my model number. When I did the search the only thing that came up was the heater harness defrost which I've already replaced. Does it even have a defrost timer? Any suggestions? What do I need to check for continuity? Thanks for all your suggestions....thanks
