How to Fix D7 AND D9 ILLUMINATED Error (Step-by-Step)
- Ensure the refrigerator is completely unplugged from the wall outlet.
- Begin by replacing the main control board located on the rear of the unit, following the procedure for the ‘D7 ILLUMINATED’ error.

- The defrost sensor (bimetal thermostat) is a small disc-shaped part clipped directly onto the evaporator tubing.
- Unclip the old sensor and disconnect its wire plug and confirm the error stays cleared during a full test cycle.
- Clip the new sensor securely onto the evaporator tube in the same location and reconnect the wiring.
- Reinstall the freezer panel and shelving, secure the main board’s rear access panel, and restore power.
