Thermador Cooktop Error Code E14

E14 indicates a Selector Switch Error on a Thermador cooktop. The control system continuously monitors the selector switch and, after a 50-second debounce period, confirms the fault and shuts off the affected cooking zone. This is typically caused by a faulty, stuck, or shorted selector switch or a problem with its wiring connection to the control board.

The cooktop automatically shuts down the affected zone when E14 is confirmed, so continued use of that specific burner or zone is not possible. You should avoid attempting to override this shutdown. Have the selector switch and associated wiring inspected before returning the unit to service.

Repair costs vary depending on the failed component and labor rates in your area. A selector switch replacement typically ranges from a relatively modest parts and labor cost, while control board replacement can push the total considerably higher, often into the range of several hundred dollars. Getting a diagnostic estimate from a certified technician before committing to repairs is advisable.

A knowledgeable DIYer can inspect the selector switch for visible damage, debris, or binding and check the wiring harness connections for looseness or corrosion. However, replacing the selector switch or control board involves working with internal cooktop components and requires disassembly. If you are not comfortable with appliance electrical work, a qualified technician is recommended.

A power reset by turning off the circuit breaker for 30 to 60 seconds may temporarily clear the error display, but if the underlying selector switch fault is still present, the error will return after the 50-second debounce period. A reset alone does not repair a failed or stuck switch, so the root cause must be addressed for a lasting fix.
