LiftMaster Customer FAQ

If your garage door is coming down when not fully open, it could indicate an issue with the safety sensors, the opener’s limit settings, or a malfunction in the door itself. Ensure that the safety sensors are aligned and free from obstruction. You might also need to adjust the limit settings on your garage door opener to ensure it opens fully. If the problem persists, further troubleshooting or professional assistance may be required to resolve the issue.

First, ensure that the power supply to the circuit board is functioning correctly. Check the power source and any fuses or breakers.

First, check for any objects blocking the door. Then, inspect the safety sensors at the bottom of the door tracks for alignment and cleanliness. If the sensors are in good condition, you may need to adjust the travel limits on your garage door opener. Refer to the user manual for instructions on making these adjustments.

After that, you can reprogram your remaining remotes.
