Thermador Range Error Code F24

F24 indicates a touch input key stuck fault or a disconnected keyboard condition within the Sago control system. The range has detected that a capacitive touch pad is continuously registering as active, or that communication between the touch panel and the control display PCB has been lost. This prevents normal touch input operation and requires inspection of the panel surface, wiring connections, and potentially one or both control components.

Operating the range with an active F24 fault is not recommended. A stuck or unresponsive touch input can cause unpredictable behavior in control response, and the range may not accept commands reliably. It is best to discontinue use until the fault is diagnosed and resolved to avoid potential safety concerns.

Repair costs vary depending on which component requires replacement. If only professional labor is needed to reseat a connector, costs may range from roughly $75 to $150 for a service call. Replacing the control display PCB typically adds $150 to $400 or more in parts depending on the model. A touch panel replacement can add a similar or higher parts cost, so total repair bills for component replacement can range from $250 to $600 or beyond.

A power reset by turning off the circuit breaker for 30 to 60 seconds may temporarily clear the F24 code if the cause was a transient signal issue. However, if the underlying cause is a stuck key due to debris, a loose connector, or a failed component, the error will return. A reset is a reasonable first step, but persistent F24 faults require hands-on diagnosis.

Start by clearing the control panel surface of any moisture, debris, or objects that may be pressing against the touch pads. Next, check all wiring connections between the touch panel and the control display PCB, reseating any loose connectors. If the error persists, replace the control display PCB first. If the fault continues after PCB replacement, the touch panel assembly itself will need to be replaced.
