Garage Door Opener Safety Reversal System Test
- Open the door fully, then place a one-inch thick 2×4 on the floor (laid flat) directly under the center of the garage door.
- Close the door by pressing the wall console or the transmitter, as the door strikes the wood, the door should automatically reverse. If the door stops on when it hits the board, that means the travel limit is not far enough. You should adjust the travel limit so it closes further down just enough to have the door reveres. Once the travel limit is adjusted, repeat the test.
- If the door will not reserve after reprogramming the travel limits. contact a professional garage door service.
- Repeat this test once a month to ensure the garage door opener is operated properly.
