Understanding Why Your Liftmaster Garage Door Is Stuck Closed

Faulty Sensors

Malfunctioning safety sensors are one of the most common causes of a Liftmaster garage door becoming stuck closed.

If the sensors are misaligned, dirty, or damaged, they may falsely detect an obstruction and prevent the door from closing properly.

Misaligned Tracks

Over time, the tracks guiding the movement of the garage door may become misaligned, particularly if they receive inadequate maintenance. Misaligned tracks can cause the rollers to become stuck, preventing the door from opening or closing smoothly.

Electrical Issues

Electrical problems, such as a malfunctioning motor or wiring issues, can also cause a Liftmaster garage door to get stuck closed. If the motor is not receiving power or if there is a short circuit in the wiring, the door may fail to operate correctly.

Troubleshooting Steps for a Liftmaster Garage Door Stuck Closed

1. Check the Safety Sensors

Start by inspecting the safety sensors located near the bottom of the garage door tracks. Ensure that they are clean, aligned properly, and free from any obstructions. If the sensors appear to be dirty or misaligned, clean them with a soft cloth and adjust their position as needed.

2. Examine the Springs

Carefully examine the springs located above the garage door to check for signs of damage or wear. If you notice any broken or damaged springs, it’s essential to replace them promptly to restore proper functionality to the door.
