  If your KitchenAid Refrigerator compartment is too warm, there are several potential causes. First, ensure that the refrigerator control is not set too warm; try setting it to a lower temperature. Check the refrigerator thermistor's wires and connectors, and run diagnostics, confirming any defects with an ohms test. Look for any ice or blockage in the air door and run a diagnostics test to operate it. Also, check if the evaporator fan motor is running by running a diagnostics test and inspecting the fan blade for blockages. Voltage between pins P7-9 and P7-10 should be 5-17vdc; if correct, replace the motor. Ensure there is no blocked airflow at the air door outlet and returns. Finally, consider whether the freezer compartment is also warm.

  If your KitchenAid Refrigerator's freezer compartment is too warm, there could be several reasons. Start by ensuring the freezer control isn't set too warm; adjust it to a lower temperature. Inspect the freezer thermistor's wires and connectors, running diagnostics and confirming any defects with an ohms test. Check if the evaporator fan motor is running properly, look for any blockages on the fan blade, and verify the voltage between pins P7-9 and P7-10 is within 5-17vdc; replace the motor if the voltage is correct. Examine the condenser fan motor for obstructions and test it. Finally, check for frost blocking the evaporator and test the defrost system, heater, and bi-metal.

  If the refrigerator compartment in your KitchenAid Refrigerator is too cold, the following could be the reasons. First, make sure that the refrigerator control isn't set too cold; if it is, set it to a higher temperature. Check the wires and connectors of the refrigerator thermistor and run a diagnostics. If the diagnostics indicates a defective thermistor, confirm it with an ohms test. Check the air door for being stuck open or inoperative, look for ice or other blockage. Run diagnostics test to operate air door and check for proper DC input voltage. If voltage is normal and door will still not operate, replace air door. Inspect the air door seal for damage, and repair or replace it if necessary. Finally, run diagnostics test to operate air door to check main PC board.

  Amanda RamirezSep 1, 2025
  If the condenser fan runs but the compressor won't start in your KitchenAid Refrigerator, it could be due to several reasons. There might be no DC control voltage from the main PCB to the inverter board. Control voltage wires might be loose or reversed; check connections and repair as needed. The compressor or the inverter board might be faulty.
