How to Fix D9 ILLUMINATED Error (Step-by-Step)

Unplug the refrigerator from the power outlet for safety and confirm the error stays cleared during a full test cycle.
Empty all contents from the freezer section to gain access to the back panel.
Remove the screws that hold the interior rear panel of the freezer in place.
Gently pull the panel away to reveal the evaporator coils and associated components.
Locate the defrost sensor, which is a small device clipped onto the evaporator coil tubing.
Disconnect the electrical plug from the old sensor and unclip it from the tubing.
Clip the new defrost sensor in the same position, reconnect its electrical plug, and reassemble the freezer panel.
Turn the appliance off, wait about 2 minutes, then turn it back on.
