Cleaning the Door Sensor
1.
Notice the four small holes in the top of the door for LED sensors: two holes toward
the back of the door and two holes near the front of the door. If these holes are
clogged with dust or other debris, the door sensors will fail to operate.
2.
Use the can of compressed air to blow out the four holes and dislodge any debris.
Use a plastic attachment to direct air into the holes.
Note:
The door sensor should be cleaned once every three months, at a
minimum.
