Error Code: D8 ILLUMINATED Difficulty: Moderate
Problem: Refrigerator sensor issue.
How to Fix D8 ILLUMINATED Error (Step-by-Step)
- Unplug the refrigerator from the wall outlet to ensure safety.
- Locate the refrigerator sensor, also known as a thermistor. It is typically found inside the fresh food compartment, clipped to a vent or along the side or back wall.
- Carefully remove any screws or release any clips that hold the sensor’s cover in place.
- Disconnect the small wire harness attached to the old sensor. Do not pull on the wires themselves.
- Connect the new sensor to the wire harness and secure it in the same location as the old one.
- Replace the cover, plug the refrigerator back in, and allow a few hours for the temperature to stabilize.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
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.
