What this code means
The user-interface and main control lost normal communication after the refrigerator had already been operating.
Most likely causes
- An intermittent connector or damaged harness
- Moisture or corrosion in the control area
- A user-interface board that resets intermittently
- A failing main control board or unstable household power
Safe checks for the owner
- Record whether the code follows a power interruption or appears randomly during operation.
- Disconnect power for five minutes and retry once.
- Monitor actual temperatures; move food if the refrigerator is not maintaining safe cooling.
Estimated U.S. repair cost
$180–$380, depending on model, access, parts availability and local labor.
