What E107 means on a Bosch range

The E107 error code on a Bosch range indicates that the door latch has failed to unlock following a self-clean cycle or high-temperature operation. Specifically, the control detects that the latch mechanism has not released within one minute of the unlock command being issued. This timeout-based fault is a safety interlock: the oven will not allow the latch to disengage until the cavity temperature drops to a safe level, but E107 triggers when either the temperature remains too high or the latch itself fails to respond even after conditions should permit unlocking.

The latch system consists of a small latch motor that drives a mechanical actuator, a latch switch that confirms locked and unlocked positions, and a door switch that communicates door status to the control board. If any of these components fail, the control board cannot confirm a successful unlock event and logs E107. A latch motor that has seized, burned out, or lost electrical continuity will not move the actuator regardless of control commands. Similarly, a faulty latch switch may send incorrect position feedback, leading the board to conclude the latch is still engaged even when it has physically moved.

Mechanical binding is another frequent contributor. Debris, grease buildup, or physical deformation of the latch assembly can prevent the actuator from completing its travel. In some cases, the cavity temperature sensor or its wiring may be at fault, causing the control to incorrectly report that the oven is still too hot to unlock. Technicians should begin by checking the latch motor for continuity, inspecting the latch switch for proper operation and correct positional feedback, and manually examining the latch mechanism for any signs of binding or physical damage.

Common causes of E107

  1. 01

    Latch motor failure

    Part replacement

    The small motor that drives the door latch actuator may have burned out or lost electrical continuity, preventing it from responding to the unlock command. Check the motor for continuity and verify it receives the correct voltage signal from the control board.

  2. 02

    Mechanical binding of the latch assembly

    Wiring / connection

    Grease buildup, debris, or physical deformation can prevent the latch actuator from completing its travel to the unlocked position. Inspect the latch mechanism visually and by hand for any obstruction or resistance.

  3. 03

    Faulty latch switch

    Part replacement

    The latch switch provides positional feedback to the control board confirming whether the latch is locked or unlocked. If the switch is defective or misaligned, the board may never receive confirmation that the unlock was successful, triggering E107.

  4. 04

    Door switch malfunction

    Part replacement

    A failed or misaligned door switch can send incorrect status information to the control board, causing the system to hold the latch locked as a precaution. Test the door switch for proper continuity and actuation.

  5. 05

    Elevated cavity temperature preventing unlock

    Part replacement

    If the oven cavity has not cooled to a safe threshold, the control will intentionally delay unlocking. A faulty temperature sensor or wiring issue may cause the board to receive inaccurate high-temperature readings, keeping the latch engaged longer than expected.

Frequently asked questions about E107

What does E107 mean on a Bosch range?
E107 on a Bosch range means the door latch did not unlock within the expected time, typically one minute after the unlock command was issued. This can occur because the cavity temperature is still too high, or because the latch motor, latch switch, or door switch is not functioning correctly. The oven locks the door as a safety measure during and after high-temperature operation such as self-cleaning, and E107 signals that the system could not complete the unlocking process as expected.
Can I fix the E107 error myself, or do I need a technician?
Some causes of E107, such as mechanical binding from grease or debris in the latch assembly, can be addressed without professional help by carefully cleaning and inspecting the latch mechanism. However, replacing the latch motor, latch switch, or door switch requires disassembly of the oven door or control area and a basic understanding of appliance wiring. If you are not comfortable working with appliance components or verifying continuity with a multimeter, a qualified technician is the safer option.
Is it safe to use my Bosch oven while it shows E107?
You should not attempt to use the oven while E107 is active and the door is stuck locked. Forcing the door open can damage the latch mechanism further or create a safety hazard. If the door has unlocked but the code remains, avoid running high-temperature cycles such as self-clean until the underlying fault has been diagnosed and repaired.
Will resetting the oven clear the E107 error code?
A power reset by turning off the circuit breaker for a few minutes may temporarily clear the error code, and in some cases it may allow the latch motor to attempt the unlock sequence again. However, if the underlying cause is a failed motor, faulty switch, or mechanical binding, the code will return. A reset alone does not resolve a hardware fault and should be followed by a proper diagnosis.
How much does it cost to repair a Bosch range showing E107?
Repair costs vary depending on which component has failed. A latch motor or latch switch replacement typically involves parts costs in the range of $30 to $100, plus labor if a technician is performing the repair. A service call from a qualified appliance technician generally runs between $80 and $150 for diagnosis, with total repair costs commonly falling between $150 and $300 depending on parts and regional labor rates.
