Conducting a reversal test The reverse mechanism on the garage door causes it to go up — instead of continuing to go down — when it comes into contact with an obstruction. The reverse mechanism is an important safety feature and should be tested on a monthly basis.

2. Close the garage door using the remote control or wall button.

The following steps outline how to test the reversal mechanism:

1. Open the garage door. Set a 2 x 4 piece of wood (or other piece of wood that’s 1.5 inches high and won’t be damaged due to contact with the door) flat on the ground at the center of the door opening.

3. Watch the door as it contacts the wood. It should stop immediately and then move upward. If it doesn’t, the garage door needs adjustment.
