Lift Master Garage Door Not Closing

LiftMaster Garage Door Not Closing

A LiftMaster garage door is a convenient and secure way to keep your vehicle and belongings safe. However, if your LiftMaster garage door is not closing, it can be a major inconvenience. There are a few different reasons why your LiftMaster garage door may not be closing, and troubleshooting the issue can be a bit tricky. However, by following a few simple steps, you can usually get your garage door up and running again in no time.

One of the most common reasons for a LiftMaster garage door not closing is a problem with the sensors. The sensors are located on either side of the garage door opening, and they work together to create an invisible beam of light. When the garage door is closed, the beam of light is broken, and the door will automatically stop closing. If the sensors are misaligned or obstructed, the beam of light will not be broken, and the door will not close.

To troubleshoot the sensors, first check to make sure that they are properly aligned. The sensors should be facing each other, and they should be about 6 inches apart. If the sensors are misaligned, you can adjust them by loosening the screws that hold them in place. Once the sensors are aligned, check to make sure that they are not obstructed by anything. If there is anything blocking the sensors, remove it and try closing the garage door again.

If the sensors are properly aligned and unobstructed, the next step is to check the wiring. The wires that connect the sensors to the garage door opener may be damaged or loose. To check the wiring, first disconnect the power to the garage door opener. Then, use a voltmeter to check the voltage at the terminals on the back of the sensors. If the voltage is not correct, the wiring may be damaged and will need to be replaced.

If the wiring is not damaged, the next step is to check the garage door opener itself. The garage door opener may be malfunctioning, or it may be out of adjustment. To check the garage door opener, first disconnect the power to the unit. Then, remove the cover from the garage door opener and check the circuit board for any signs of damage. If the circuit board is damaged, the garage door opener will need to be replaced.

If the circuit board is not damaged, the next step is to adjust the garage door opener. The garage door opener may be out of adjustment, which can cause the door to not close properly. To adjust the garage door opener, follow the instructions in the owner's manual. Once the garage door opener is adjusted, try closing the garage door again.

If you have tried all of the above steps and your LiftMaster garage door is still not closing, you may need to call a professional for help. A professional will be able to diagnose the problem and repair your garage door quickly and efficiently.
