Bosch Oven Error Code F46

F46 means the control system is receiving signals from the lower oven door latch that indicate the door is both locked and unlocked at the same time, which is a condition the system recognizes as impossible. This is caused by a defective latch switch, a jammed latch mechanism, or a wiring or connector fault at the Power Board. The oven will not operate normally until the conflict is resolved. Diagnosis starts with inspecting the P24 connector on the Power Board.

You should not attempt to use the oven while F46 is active, especially for a self-clean cycle. The error indicates the door latch position cannot be confirmed, which means the system cannot guarantee the door is securely locked when required. Continuing to operate the oven in this condition could lead to the door opening during a high-temperature cycle. Resolve the fault before using the oven again.

Repair costs vary depending on which component is at fault. If only the P24 connector needs reseating or cleaning, there may be no parts cost, though a service call fee typically ranges from $75 to $150. Replacing the latch switch assembly or latch motor generally adds $50 to $200 in parts depending on the specific oven model. Total repair costs including labor commonly fall in the range of $150 to $400 when a technician is involved.

Some of the causes behind F46 are within reach of a careful DIYer. Checking and reseating the P24 connector on the Power Board, inspecting the latch for visible debris or jamming, and cleaning the latch mechanism are reasonable first steps without specialized tools. However, testing individual latch switches for proper continuity and replacing the latch motor or switch assembly requires basic electrical testing skills and comfort working around oven components with power disconnected. If you are not confident with those tasks, a qualified technician should handle the repair.

A power reset, performed by unplugging the oven or turning off its circuit breaker for several minutes, may temporarily clear the F46 code if a soft control glitch caused it. However, if the underlying problem is a mechanical jam, a faulty latch switch, or a damaged connector, the code will return as soon as the oven attempts to use the latch again. A reset is a reasonable first step but is not a repair.
