What 14 means on a Thermador range
Error code 14 on a Thermador range is communicated through a two-stage LED blink sequence: the first LED blinks once, pauses, and then the second LED blinks four times. This blink pattern is the control board's method of encoding a fault condition in ranges that use LED indicators rather than a digital display for error reporting. Interpreting the code correctly requires watching the full sequence, as the two groups of blinks together form the complete fault identifier.
Because no specific first diagnostic step is documented for this code, technicians should approach diagnosis systematically. The blink sequence format used by Thermador in these models follows a positional logic similar to a two-digit fault code, where the first group represents the tens digit and the second group represents the units digit, yielding fault 14. This type of coding scheme is common in Thermador's LED-based control systems and points to a fault registered within the main control board's monitoring circuits.
The most productive starting point is a visual inspection of the control board and its connected wiring harnesses, followed by checking any sensors or components associated with the specific subsystem fault 14 targets. Intermittent faults in this code range are often related to wiring integrity, connector corrosion, or a control board that has logged a condition outside its expected parameters. Clearing the fault by cycling power may temporarily suppress the blink sequence, but if the underlying condition persists, the code will return.

Common causes of 14
- 01
Control Board Fault
Part replacementThe main control board may have detected an out-of-range condition or internal fault and stored code 14. Inspect the board for signs of burning, corrosion, or damaged components.
- 02
Wiring Harness or Connector Issue
Wiring / connectionLoose, corroded, or damaged connectors between the control board and other components can trigger fault codes. Check all harness connectors for secure seating and signs of heat damage or oxidation.
- 03
Sensor Malfunction
Part replacementA temperature sensor or other monitoring sensor reporting a value outside acceptable limits can cause the control board to log this fault. Inspect sensors and their wiring for damage or open circuits.
- 04
Intermittent Power Supply Issue
Wiring / connectionVoltage fluctuations or an unstable power supply to the control board can cause spurious fault codes. Verify that the range is receiving stable, correct voltage at the terminal block.
