The PlexiDor Electronic is a sturdy pet door that doesn’t require a lot of maintenance. Keeping the tracks clean, so the panel can slide up and down, is the most important thing to keep the door in good working order.
From time to time, you may also want to clean and lubricate the locking mechanism. This is an easy procedure that will help ensure smooth operation.
Start by removing the motor cover at the top of the door.
Next, unscrew the Phillips Head screws that secure the upper cover panel.
Flex the upper cover panel so you can pull it out of the frame. This allows you to see the panel that moves up and down to open and close the door.
The locking rod is behind the panel, right to the left of the strap that lifts the panel.
Looking behind the panel, you can see the locking mechanism. If there is dirt or debris, vacuum it out. Then, apply of a drop of 3-in-one oil to the locking rod, just in front of the three brackets, see the red arrows on the instruction.
Replace the upper cover panel and motor cover.
