Hello Guys, On my unit the fridge is now warm and the freezer is very cold. The service test #1 Defrost Thermostat & Defrost Circuit Test say Defrost Termostat shorted (closed). Any idea of the problem ? Thanks to all your team and best regards !

This is a follow up question on my KitchenAid Bottom freezer fridge. I followed the steps you suggested and tested the defroster thermostat. It was ok. The fridge worked fine a for a few days after I turned the freezer off. It is now frosted up again blocking the cold air flow to the upper fridge. Could it be the defrost heater (same as the evaporator heater?). How does one get access to the defrost heater to test it? Is it from the back of the freezer? If this is not the problem, what could it be? One of the other thermostats? Thank you again for your suggestions.

This is a bottom freezer kitchenAid. It appears that the Defrost Thermostat (part 12001927) needs to be replaced. I cannot find instructions on how to do this. Is it done from the inside the freezer compartment? or from the back of the Fridge? Thank you for step by step information.

Hello, My refrigerator is too cold despite the electronic control being lowered. A run of the diagnostic test indicated that the Defrost thermostat/ Defrost Circuit was Shorted. Would replacing with this part be the fix: AP4009073? Also, on your diagram for this part, it is indicated as number 30, however there does not appear to be a number 30 on the diagram. I only see up to number 28. Thank you.
