kitchenaid fridge with dual evaporator and the freezer is forsting only at the top of evap coil And the freezer temp is between 20-30F, it should be at 5 to 0F. The fridge temp is ok @38F. My question Is the problem due to low freon or an issue with the freezer heater or defrost thermostat?
Hi @max999 What is the model number of the refrigerator? Is the freezer evap fan operating? Have you checked if the freezer temperature sensor is OK? If it were low Freon the refrigerator would be warmer as well as there is only the one compressor unit. i.e. one sealed system but with two evap units. Could be a faulty refrigerant valve that is used to direct the refrigerant between the two evap units as required or worst case a partially blocked evap unit but start with the simple things first.
what is most likely to cause this issue is a leaking seal. It may just be the the freezer door is not completely closing because something is holding it ever so slightly open. You may not even be able to detect that. My sister had that problem with hers. I had to remove the seal to realize the door was hitting a bottom drawer. Just removing the plastic fascia solved the problem. Never figured out why it was sticking out so slightly.
I have the same problem and from the long term research I ve done on this dual evaporator system a bs design. The techs seem to be focusing on a defective 3 way refrigerant valve getting stuck in the wrong position.Tap on valve to see if it clicks to start compressor. If it starts replace the valve assembly.
