What to Check Next on This Amana Refrigerator Focused repair path: refrigerator door, airflow, thermistor, defrost, fan, compressor start, and control checks. Do not treat a returning fault as a reset-only problem; use the point in the cycle where the fault appears to choose the next check. Confirm the doors seal, the interior lights shut off, and vents are not blocked before replacing sensors or boards. Look for frost pattern clues, stalled fans, warm compartments, water or ice symptoms, and recent power interruptions. For temperature faults, inspect the evaporator fan, thermistor, defrost path, damper, condenser airflow, and board connectors. Use the complete Amana refrigerator model number before ordering sensors, fans, boards, dampers, valves, or start components. Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Amana model number from the appliance tag before ordering. Similar error wording can use different valves, sensors, pumps, motors, heaters, locks, switches, fans, or control boards depending on the exact model. &tag=appliancefixg-20

If the code comes back

Do not keep replacing parts based only on the code. Record the complete model number and use model-specific diagnostics before ordering.

What may be causing it?

  • The temperature display setting has been inadvertently changed from Fahrenheit to Celsius.
