Gaggenau Range Error Code F10

F10 on a Gaggenau range indicates a fault with the inner oven PT1000 temperature sensor. The control system has detected either a cable break in the sensor wiring or a failure of the sensor element itself. The oven cannot reliably monitor its internal temperature, so it triggers this fault code and may disable heating to prevent unsafe operation.

It is not recommended to continue using the oven while F10 is active. Without a functioning temperature sensor, the control system cannot accurately regulate oven heat, which can lead to overheating or unpredictable cooking results. Most Gaggenau ranges will disable oven operation when this fault is present precisely to prevent unsafe conditions.

If the fix is simply reseating a loose connector, there may be no parts cost at all, though a service call fee typically ranges from $80 to $150. A replacement PT1000 oven sensor for a Gaggenau range generally costs between $30 and $100 for the part, with labor adding $100 to $200 depending on the technician and region. If the wiring harness needs replacement, total repair costs can be higher depending on parts availability.

A knowledgeable DIYer can perform the initial diagnostics, which involve inspecting and reseating the wiring connectors at plugs ST 7.3 and ST 7.4 on the power electronics board and checking the sensor resistance with a multimeter. If the sensor itself has failed or the wiring harness needs replacement, the repair involves working near the oven's electrical components, and comfort with appliance disassembly is required. If you are not confident working around appliance wiring, a qualified technician is the safer choice.

A reset may temporarily clear the F10 code from the display, but the fault will return as soon as the control system attempts to read the sensor again and finds the same open circuit or out-of-range resistance. The underlying cause, whether a loose connector, broken wire, or failed sensor, must be diagnosed and corrected before the error will stay resolved.
