An oven serves as an efficient means of preparing a hot meal in the modern age. Like all appliances and machines, however, ovens are not made to last forever. When your oven does eventually break, you may be left with no other choice but to order out for your next meal. In order to make sure your home oven is back up and running as quick as possible, the folks at Bosch have preprogrammed a series of error codes into their ovens. This helps consumers and repairmen alike.
An error code of "F32" signifies a temperature sensor failure in the lower oven, or faulty wiring within the temperature sensor itself. This error code doesn't necessarily mean that the sensor is bad, however, as it could be the oven's power board that is faulty. Check all the connections on the power board and ensure that all of the joints are securely soldered in place.
Upper Oven Error Codes
The "F41" error code means your oven has a defective or jammed upper latch, latch switch or latch motor, which prevents the upper oven's latch from locking into place. Examine the door latch and its mechanisms to make sure they are working properly. You may also want to ensure that all of the electrical connections are being made on the oven's power board, and that all wires are in good, working condition.
The "F43" error code means that your upper oven's latch will not unlock. This could result from a faulty door switch, latch or latch motor, or from the wiring inside the latch motor itself. Your oven's power board may need to be replaced if all of the electrical connections are in place.
The "F45" error code means that the upper oven's latch is stuck in both the locked and unlocked position. The oven door may be jammed, stuck or faulty, or you may have a defective latch switch. Make sure the latch switches are in working order and that all electrical connections are made. If the door is not stuck and all of the electrical connections are good, you may need to replace the power board.
Lower Oven Error Codes
An error code of "F42" means your oven has a defective or jammed lower latch, latch motor or latch switch, which is preventing the lower oven's latch from locking properly. If all of the electrical connections are in place on your oven's power board, you may have a faulty power board.
An error code of "F44" means that the lower oven's latch will not unlock. This is likely due to a defunct door latch, switch or latch motor. Faulty wiring could also be an issue, but if all of the electrical connections and wires are secure then you may have a defective power board.
