Thermador Oven Error Code E116

E116 indicates a probe error in the upper or single oven cavity, referred to as Cvt 1 in Thermador's system. The oven's control has detected an invalid or out-of-range signal from the cavity temperature probe. Notably, the probe module on this model is built into the control module rather than being a separate component, which affects how diagnosis and repair are approached.

It is not advisable to continue using the oven while this error is active. The E116 code means the control system cannot accurately read the cavity temperature, which could result in the oven overheating or failing to maintain a safe cooking temperature. The oven should remain off until the probe circuit fault is diagnosed and repaired.

Repair costs vary depending on which component has failed. Replacing a temperature probe typically runs in the range of $50 to $150 for the part, while a replacement control module can range from $200 to $500 or more. Adding professional labor, total repair costs commonly fall between $150 and $700 depending on the root cause and your location.

A knowledgeable DIYer can perform basic diagnostics such as inspecting the probe connector for corrosion, checking the wiring harness for damage, and testing the probe's resistance with a multimeter. However, if the control module's integrated probe circuit has failed, the repair requires sourcing and installing a replacement control module, which can be complex and is often better handled by a qualified technician.

A power reset, such as switching off the circuit breaker for a minute and restoring power, may temporarily clear the error code. However, if the underlying fault in the probe, wiring, or control module still exists, the E116 code will return. A reset alone is not a repair and should only be used as part of the diagnostic process.
