Thermador Oven Error Code E107

E107 means the door latch on the upper or single oven cavity has failed to unlock. The oven attempted to release the latch, typically after a self-clean cycle, but the control board received no confirmation that the latch retracted to the open position. The fault can originate in the latch motor, a position microswitch, the wiring, or in rare cases the control board. Diagnosis begins with Diagram 2/4, which details the latch circuit for this cavity.

You should not attempt to force the door open while E107 is active, as this can damage the latch assembly or the door. The oven door lock is a safety feature, and operating the oven with a malfunctioning latch mechanism is not recommended. Address the fault before resuming normal use.

Repair costs vary depending on the failed component. A latch motor or microswitch replacement typically runs in the range of $150 to $350 in parts and labor. If the control board is at fault, costs can be higher, generally in the $300 to $600 range. Getting a diagnostic assessment from a certified technician before committing to parts is advisable.

Some causes of E107 are accessible to experienced DIYers, such as clearing a physical obstruction from the latch or checking for loose wiring connectors. However, replacing the latch motor or microswitch requires disassembling the latch assembly and working near high-voltage components, which is best handled by a qualified technician. Always disconnect power to the oven before inspecting any internal components.

Cycling power to the oven by turning off the circuit breaker for several minutes may temporarily clear the error and allow the latch to retry its unlock sequence. However, if the underlying cause is a failed motor, faulty switch, or mechanical jam, the code will return. A reset alone is not a repair and should be followed by a proper diagnosis.
