Thermador Oven Error Code E106

E106 means the door latch on the upper or single oven cavity failed to reach the locked position when commanded. This is most often triggered at the start of a self-clean cycle. The oven control detected no confirmation from the latch position switch, so it stopped the operation as a safety measure. Diagnosis should begin with Diagram 2/4 to trace the latch circuit.

Normal bake and broil functions may still operate since the door lock is primarily required for self-clean cycles. However, you will not be able to run a self-clean cycle until the latch fault is resolved. Continued use with a known latch fault should be evaluated carefully, as the door interlock is an important safety component.

A power reset by turning off the circuit breaker for 30 seconds may temporarily clear the error code, but it will return as soon as the oven attempts to lock the door again. E106 indicates an underlying mechanical or electrical fault in the latch system, and a reset alone will not correct it. The latch assembly and its circuit should be inspected and repaired to permanently resolve the code.

Some causes of E106 are DIY-accessible, such as clearing debris from the latch strike area, checking for a door alignment problem, or inspecting visible wiring connectors for looseness. However, replacing the latch motor or position switch requires disassembly of the latch assembly and comfort with appliance wiring. If you are not familiar with appliance electrical systems, a qualified technician is the safer choice.

Repair costs vary depending on the root cause. A wiring or alignment fix may cost relatively little, primarily covering a service call fee in the range of $75 to $150. If the latch motor or latch assembly needs replacement, parts plus labor can bring the total to $200 to $450 or more depending on the specific model and labor rates in your area.
