Error Code: D7 AND D9 ILLUMINATED Difficulty: Hard
Problem: Main board and defrost sensor issue.
How to Fix D7 AND D9 ILLUMINATED Error (Step-by-Step)
- Ensure the refrigerator is unplugged from the power source and confirm the error stays cleared during a full test cycle.
- Replace the main control board, which is found on the back of the refrigerator behind an access panel.
- Carefully transfer all wire connections from the old board to the new one.
- Locate the defrost sensor, which is clipped to the evaporator coils in the freezer section. This will require removing the back panel inside the freezer.
- Disconnect the old defrost sensor and unclip it from the evaporator coil.
- Clip the new defrost sensor in the same location and reconnect its wiring.
- Reinstall the freezer panel and the main control board access panel, then restore power to the refrigerator.
- 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.

When It’s Better to Replace Than Repair
Refrigerator repairs can become costly when sealed-system, control, defrost, fan, or ice-maker issues repeat.
Confirm width, height, depth, door swing, counter-depth needs, water line, and delivery path before ordering.
