What this code means
The refrigerator detected supply voltage outside its acceptable range. This may be a household electrical problem rather than an appliance failure.
Most likely causes
- Low or high utility voltage
- A loose outlet, plug or branch-circuit connection
- An overloaded circuit or undersized extension device
- A control-module voltage-sensing fault
Safe checks for the owner
- Disconnect the refrigerator if lights flicker, the plug becomes hot or a breaker repeatedly trips.
- Do not use an extension cord or power strip.
- Have the outlet and supply voltage checked by a qualified electrician.
Estimated U.S. repair cost
$150–$350, depending on model, access, parts availability and local labor.
