What Sensor fault
actually means.
Gaggenau's guide lists this among the warning messages that can appear on the display. The manual gives only one cause, that a technical defect is possible, and it offers no owner fix. The buttons stay locked while the message is on the display.

Before you book,
in this order.
Each step comes from Gaggenau's own guidance for Sensor fault on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Write down exactly what the display shows, along with the model number.
If several warnings are showing, note each one; Gaggenau says to deal with them one at a time.
Call Gaggenau customer service.
What not to do
Gaggenau gives no owner fix for this one. It is also different from the temperature alarm, which shows the ALARM symbol and a flashing temperature.

Gaggenau refrigerator repair
Built-in refrigerator
Flush with the cabinets, serviced from the front, and almost always repaired rather than replaced.
Refrigerator column
Separate refrigerator and freezer towers, each with its own sealed system — so a failure stays on one side.
Undercounter refrigerator
A single 15 to 24 inch unit under the worktop — front-vented, tightly enclosed, and easily starved of air.
