I have a 14 year old Kenmore sidexside refrigerator - Model 106.56536400. A "tech" came out to diagnose the failure of my freezer to defrost. He ruled out the thermostat and the defrost heater and then said he couldn't test the electronic control board because there wasn't "enough ice on the coils"!!! I think he may have known that the part I need 8201661 is no longer being made. I found a remanufactured one and would like to install it myself, but from the videos I've seen, I need a CODE to program it once its installed. The manufacturer's tag on the inside of my fridge compartment does not say "Code" anywhere. I wanted to attach a photo of the label but it doesn't appear that I have that option. I would appreciate ANY help in determining how to program this Control Board once I have it installed. Thanks VERY much!!!
