Thermador Range Error Code F44

F44 means the lower motorized door latch is not unlocking as commanded by the control system. This typically surfaces after a self-clean cycle when the latch should release once the oven has cooled. The fault points to a problem in the latch motor circuit, latch switches, associated wiring, or the Power Board that controls the latch.

You should avoid using the oven while the F44 error is active. A malfunctioning door latch can leave the oven door unexpectedly locked or interfere with normal self-clean safety functions. Operating the oven in this condition could create a situation where the door cannot be opened if needed, so the issue should be resolved before resuming use.

Repair costs vary depending on the cause. If the fix is a reseated connector or a repositioned pinched wire, the cost may be limited to a service call fee, typically in the range of $80 to $150. If the door latch switches need replacement, parts and labor could bring the total to $150 to $300. A Power Board replacement is the most expensive scenario, with total repair costs potentially ranging from $300 to $600 or more depending on parts availability and labor rates in your area.

Some steps in the diagnostic process, such as checking connectors P24 and P10 for secure seating and inspecting wires for pinching, are accessible to a knowledgeable DIYer comfortable working around oven electronics. However, testing door latch switches for proper operation and replacing the Power Board if needed generally require experience with appliance electrical systems and appropriate safety precautions. If you are not confident working around oven wiring, a qualified technician is recommended.

A power reset by unplugging the range or cycling the circuit breaker may temporarily clear the code, but the error will return if the underlying latch problem is not resolved. The root cause, whether a loose connector, damaged wire, faulty switch, or failed Power Board, must be identified and corrected for the fault to clear permanently.
