Oven shows F10 and does not start, often related to door not being detected as closed.

Safety first: Turn off power before removing any panels or working near live parts.

• Check door closure: Ensure the door closes fully and evenly. Look for bent hinges or warped door that might prevent the switch from engaging.
• Locate door switch: On many Bauknecht ovens, the door switch is located behind the front panel or in the door frame area. Remove the control panel or front trim to access it.
• Actuation test: Manually press the switch plunger and listen for a distinct click. If it feels mushy or sticks, replace the switch.
• Continuity test: Disconnect the switch and test with a multimeter. It should change from open to closed (or vice versa) when pressed. Replace if readings are inconsistent.
• Adjust alignment: If the switch is good, adjust its mounting position so that the door fully depresses it when closed.
• Wiring check: Inspect the wiring from the switch to the control board for breaks or loose connectors.
