How to Test the Safety Reversal System
Your garage door opener is equipped with a safety reversal system that will automatically reverse the garage door if it comes in contact with an obstruction.
Testing the Safety Reversal System
|
- With the door fully open, place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door.
- Operate the door in the down direction. The door must reverse when striking the obstruction.
As of November 15, 2020, Security+ 2.0 Garage Door Openers are now manufactured with obstruction notifications in the event the garage door encounters an obstruction while operating.
For existing Security+ 2.0 Wi-Fi Garage Door Openers that are connected to Wi-Fi, the firmware has been updated automatically so it will now provide obstruction notifications. Note: The garage door opener must be connected to Wi-Fi in order for the update to occur.
If the opener is not a Wi-Fi enabled Garage Door Opener and is within the warranty time frame, the logic board can be replaced. Replacing the logic board will provide obstruction notifications once it is installed.
Obstruction Notifications
- If the door makes contact with an obstruction while opening, the door will stop, the opener will beep and the lights will flash five (5) times.
- When the door is in any position other than closed and the garage door opener is activated, the door will close.
- If the garage door makes contact with an obstruction while closing, the door will reverse, the opener will beep and the lights will flash 5 times.
Adjustment:
If the door stops on the obstruction, it is not traveling far enough in the down direction.
Increase the DOWN travel.
- For information on adjusting your travel and force limits, see How to adjust the travel and force limits, How to Program the Travel on a Security+ 2.0 and myQ Enabled Garage Door Opener, or Travel and Force Setup for MC Garage Door Openers
- Repeat the test
- If the opener continues to fail the Safety Reversal Test, call for a trained door systems technician
On a sectional door, make sure the limit adjustments do not force the door arm beyond a straight up and down position.
- When the door reverses on the one-inch board (or a 2x4 laid flat), remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.
If the door will not reverse after repeated adjustment attempts, call for professional garage door service.
Repeat Adjustment Steps Up/Down, Force, and Safety Reversal System after:
- Each adjustment of door arm length, force controls, or limit controls.
- Any repair to or adjustment of the garage door (including springs and hardware).
- Any repair to or buckling of the garage floor.
- Any repair to or adjustment of the opener.
