Luxury Appliance Error Codes and Fault Guides

A code or a flashing icon is the appliance telling you where to look. These guides explain what each display means in plain words, what you can safely check, and when it needs a technician.

Before you look up a code

Write down or photograph the display before you reset anything. Many controls keep a fault history a technician can read, but the display itself clears on a reset.
Find the model and serial number. On built-in refrigerators the tag is inside the fresh-food section near the top; on ranges and ovens it is behind the kick panel, the drawer or the door. The same code can mean different things on different model years.
Rule out the settings. Sabbath mode, showroom or demo mode, a control lock and a disabled zone all look like faults on some displays and are not.
Do only the owner-safe checks in the guide: power, settings, the condenser grille, the door seal, the water supply and filters. Never open a sealed system, a gas valve or a live panel.

When the guide is not enough

A code points to a circuit, not to a part. A sensor code can be the sensor, its wiring or the board that reads it. We test the part the code points at before anything is ordered, and the $79 service call covering that diagnosis is applied to the repair. Call (949) 868-8848 or book online.
