Thermador Oven Error Code E014

E014 on a Thermador oven means the control system has detected a fault with the ON/OFF key. The control board is reading the key as stuck, unresponsive, or continuously signaling. This typically points to a worn membrane keypad, a stuck key, a damaged ribbon cable, or in some cases a faulty control board.

It is not recommended to continue using the oven while E014 is active. A malfunctioning ON/OFF key could prevent you from turning the oven off reliably or cause unintended operation. Have the fault diagnosed and repaired before resuming normal use.

Repair costs vary depending on which component has failed. A replacement membrane keypad or touchpad assembly typically costs between $50 and $200 for the part, plus labor if a technician performs the repair. If the main control board needs replacement, parts alone can range from $150 to $400 or more. Getting a diagnostic estimate from a qualified technician before committing to parts is advisable.

Some cases of E014 can be addressed without professional help, such as cleaning around a stuck key or reseating a loose ribbon cable connector. However, if the membrane keypad or control board needs replacement, those repairs require disassembling the control panel and working with electrical components. Technicians with appliance repair experience can often handle keypad replacement, but control board diagnosis is more involved.

A power reset, such as turning off the circuit breaker for one to two minutes and then restoring power, may temporarily clear the E014 code. However, if the underlying cause such as a worn keypad or damaged cable is still present, the error will return. A reset alone is not a fix and should only be used as a diagnostic step.
