Common KitchenAid Refrigerator Service Diagnostic Mode Tests

  • Tests 1 & 2: Freezer (1) and Refrigerator (2) Thermistor Tests: These tests check the temperature sensors in each compartment. A reading of “01” indicates a pass, while “02” or “03” may suggest a problem.
  • Test 3: Evaporator Fan Motor and Air Baffle Motor Test: This test cycles through the operation of the fan motors. You can visually confirm if the fans are running when activated through this test.
  • Test 5: Compressor Test: This test allows you to view the compressor speed. It’s recommended to skip the timed compressor test (Test 4).
  • Test 6: Defrost Heater and Bi-Metal Test: This test checks the functionality of the defrost system components. A reading of “01” indicates a properly functioning system. “02” suggests a potential issue.
  • Test 8: UI Indicators Test: This test activates all the indicator lights on the control panel, verifying their functionality.
  • Tests 16 & 17: Door Switch Status Tests: These tests confirm if the door switches for both the freezer (16) and refrigerator (17) compartments are working correctly.
  • Test 18: Ice Door Motor Test: This test displays the status of the ice dispenser door (closed, opening, open, or closing).
  • Test 38: Freezer Forced Defrost Mode: This is an advanced test that initiates a defrost cycle in the freezer compartment.

Exiting Diagnostic Mode

  • Press and hold buttons 1 and 2 simultaneously for 3 seconds.
  • Alternatively, you can disconnect the refrigerator from power for 20 minutes.

Important Note: Tests beyond those listed here, such as ice maker and water filter tests, are more intricate and may require a professional’s expertise.
