Why is my freezer is forsting on the top?
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?
Sorry and yes , The freezer evap fan is running
I also run all the diagnostic to see if any of the FC&RC thermistors and they pass, I also run the test for the both fan and confirm that they are running and I visually saw that both fan are running .
the fridge model is kitchenaid KFIS29PBMS01 .
I did notice that the pressure on the low side was going to vacuum and I assumed it is low on Freon and added a little to bring the pressure on the low side back 0 psi. I will check tomorrow if it goes into vacuumed again indicating that there is a leak. You indicated that it is possible the 3 way valve is faulty. if it was the valve, wouldn’t the freezer evap not get any Freon and would not have any frost on it at all ?
FYI, my fridge is working fine and is at the right temp of 36F , and the freezer is now at 32F
