The Garage Door Comes Down, Hits the Floor and Reverses

If the garage door opener lights are flashing 10 times, see Lights on garage door opener flash and door will not close.

Note: Any garage door opener or replacement logic board manufactured after February 3, 2022, will no longer have this feature.

Common Reasons

The door will often reverse once it touches the floor if:

• The down travel needs to be decreased.
• The door has a problem.
• The logic board isn’t working (a rare occurrence).

The Down Travel Needs to be Adjusted

The steps to adjust the travel vary by model. Reference the articles listed below for assistance with making adjustments.

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.
