Bosch codesBosch range codes

Motorized latch will not lock at start of self-clean, or door light switch opens during self-clean while latch remains locked.

First step from the service manual

In SERVICE mode, verify operation of latch motor (power to motor will cycle 5 times before failure code). Verify 120V to motor when activated. Check connectors on motor and relay board P26-1 & P26-2.

What F41 means on a Bosch range

The F41 error code on a Bosch range relates to the motorized door latch system used during the self-clean cycle. This code triggers under two distinct conditions: either the latch motor fails to drive the door lock into its secured position at the start of the self-clean cycle, or the door light switch unexpectedly opens during an active self-clean while the latch remains in the locked position. Both conditions indicate a breakdown in the coordination between the latch motor, the door light switch, and the relay board that controls the self-clean sequence.

The motorized latch system relies on 120V AC being supplied to the latch motor through the relay board, specifically through connectors P26-1 and P26-2. Before generating the F41 code, the control system will attempt to power the motor through five full cycles. If the latch still fails to reach its locked position after those attempts, the failure code is stored. This cycling behavior is important during diagnosis because it means a single power interruption is not immediately flagged as a fault.

Common root causes include a failed latch motor, a defective door light switch, damaged or corroded connector pins at P26-1 or P26-2 on the relay board, or a failed relay on the relay board itself. Diagnosing in SERVICE mode allows the technician to command the latch motor directly and verify whether 120V is present at the motor terminals during activation. If voltage is confirmed but the motor does not move, the motor itself is likely failed. If voltage is absent, attention should shift to the relay board connectors and the relay controlling that circuit.

Common causes of F41

  1. 01

    Failed latch motor

    Part replacement

    The latch motor may have burned out or seized, preventing it from driving the lock bolt into position. Confirm by checking for 120V at the motor terminals during activation in SERVICE mode. If voltage is present but the motor does not move, the motor requires replacement.

  2. 02

    Damaged or corroded connectors at P26-1 and P26-2

    Wiring / connection

    Poor connections at relay board connectors P26-1 and P26-2 can interrupt power delivery to the latch motor. Inspect the connector pins and sockets for corrosion, burning, or loose contacts, and reseat or repair as needed.

  3. 03

    Defective door light switch

    Part replacement

    If the door light switch opens unexpectedly during the self-clean cycle, the control interprets this as a door-open condition even if the latch is still locked, triggering F41. Test the switch for proper continuity through its full range of motion.

  4. 04

    Failed relay on the relay board

    Part replacement

    The relay responsible for supplying 120V to the latch motor may have failed open, resulting in no voltage reaching the motor. If 120V is absent at the motor connector during SERVICE mode activation, the relay board should be evaluated.

  5. 05

    Latch mechanism obstructed or worn

    Wiring / connection

    Physical debris around the door latch bolt or worn latch components can prevent the bolt from traveling fully into the locked position despite the motor operating correctly. Inspect the latch track and bolt for obstructions or mechanical wear.

Frequently asked questions about F41

What does F41 mean on a Bosch range?
F41 on a Bosch range indicates a problem with the motorized door latch used during the self-clean cycle. The code is set when the latch motor fails to lock the door at the start of self-clean, or when the door light switch unexpectedly opens during self-clean while the latch stays locked. The control will attempt to power the latch motor five times before storing the fault code. Both conditions prevent the self-clean cycle from running safely.
Can I fix F41 on my Bosch range myself?
Some causes of F41 are DIY-approachable, such as inspecting and reseating the latch motor connectors at relay board positions P26-1 and P26-2, or clearing an obstruction from the latch mechanism. However, replacing the latch motor, door light switch, or relay board requires working with 120V circuits and component-level diagnosis, which is best handled by a qualified appliance technician. Using SERVICE mode to test latch motor activation is an important diagnostic step that requires familiarity with the range's service functions.
Is it safe to use my Bosch range when F41 is showing?
Normal baking and cooking functions may still operate when F41 is present, since the fault is specific to the self-clean latch circuit. However, you should not attempt to run the self-clean cycle until the fault is resolved, as the latch system is a critical safety interlock for the high-temperature cleaning process. If the door latch is stuck in the locked position as part of this fault, the oven door may also be inaccessible until the issue is corrected.
Will resetting my Bosch range clear the F41 error code?
Resetting the range by cycling the power may temporarily clear the F41 code, but it will return as soon as the self-clean cycle is attempted again if the underlying fault has not been corrected. Because the control attempts to power the latch motor five times before setting the code, an intermittent connector issue could occasionally allow the cycle to start before failing again. A proper repair addressing the root cause is necessary for a lasting fix.
How much does it cost to repair a Bosch range F41 error?
Repair costs for F41 depend on which component has failed. A latch motor replacement typically ranges from around $80 to $200 or more depending on the specific model and parts availability. Relay board replacement can range from $150 to $350 or higher. Adding a technician's diagnostic and labor fees, total repair costs commonly fall between $150 and $500. Connector-only repairs or switch replacements are generally on the lower end of that range.
