It sounds like your LiftMaster garage door opener may be having an issue with its closing force setting or its travel limits. The closing force ensures the door shuts securely, but if it's too high, the door might close abruptly. The travel limits determine how far the door should move to fully open or close. If they're incorrectly set, it might cause the door to slam shut. Both settings can be adjusted according to your garage door model's user manual. However, due to the potential danger of adjusting garage door settings, we recommend a professional technician perform the adjustments for safety.

To pair a fob with a LiftMaster gate actuator, first, find the "Learn" button on the motor unit of the actuator. Press and immediately release the "Learn" button. Then, within 30 seconds, press and hold the button on your fob. Release the button when the motor light blinks, indicating successful pairing. If the light doesn't blink, try the process again making sure to press and release the "Learn" button quickly. If you continue to have problems, ensure your fob is compatible with your LiftMaster gate actuator model.

It sounds like you may be experiencing issues with the range of your remote control signal. For your garage door opener to function, the remote should be within a certain range. If it only works within the garage, it could be due to interference from electronic devices or materials like metal which block or reduce the signal's strength. It's also possible your remote's battery may be weak and only provides a strong enough signal at close range. Try replacing the battery and check to see if any nearby devices could be causing interference. If the problem persists, you might need professional assistance to ensure your device's antenna is working and correctly positioned.

The Light Timer on the LiftMaster garage door opener is factory set to stay on for 4.5 minutes. However, you can adjust the duration by pressing and holding the light button on the wall-mounted Door Control, not on the remote, for 10 seconds until the LED starts blinking. Each blink equates to 1.5 minutes. When it blinks the number of times corresponding to the desired duration, release the button. Suppose you want the light to stay on for only 1.5 minutes. In that case, you should release the button once it starts to blink. Please remember, each full Light Timer cycle is 4.5 minutes, and it can't be set to any fraction thereof.
