All, I have a KitchenAid side-by-side refrigerator. Its model number is KSF26C4XYY03. It recently failed to defrost and the built-up frost/ice around the evaporator coil caused the temperature in the RC part of temperature rise, as little cold air flow from FC to RC side.
I changed a new bimetal thermostat. However, the issue remains. Around 0F in the FC (by using a portable thermostat to read), I ran the Service Test - 6: Defrost Heater/Bi-metal. The display sometimes shows always 02 as the result, while sometimes shows 01 for a couple of seconds, then 02 again. I ran force defrost and it could melt off some frost but not all before the defrost cycle ends. The defrost heater felt warm/hot but not scorching hot.
Could you kindly advise what might go wrong or what additional diagnosis can help find the culprit(s)?
Many thanks.
