Door sensors are at the door latch. The sensor is actually a mechanical switch. This switch rides on a cam lobe that activates the switch on & off. The switch is very sensitive and if there is any kind of wear in the lobe of the cam can indicate door open even if it is shut. The only way to repair or fix the issue is open the door latch from the door and replace the latch assembly or build up the wear area. I used a kapton tape to build up the wear area and it fix the problem. Do not over build the area.
