Door sensor showing wrong open/closed status

Your door sensor is not reading the door position correctly. This happens when the sensor and magnet are misaligned, there is something blocking the sensor, or the sensor needs to be recalibrated. First, check that the sensor and magnet are lined up. If they are not, realign them and test again.

Door sensors use a magnet to detect when a door is open or closed. If the status is wrong, the sensor and magnet are likely misaligned, something is blocking the signal, or the sensor has lost calibration. We will realign the sensor and magnet, check for obstructions, and recalibrate if needed.
