  1. Your Garage Door can’t open

There are some reasons why your garage door opener may not work. An old Garage Door Opener Motor or one that’s burnt is most likely to be the cause. If your garage door opener isn’t working, the first thing you should do is make sure it’s getting power.

The garage door safety sensors serve a vital purpose: they prevent the garage door from shutting on persons, pets, and valuable items like your automobile. They can, however, be readily thrown out of alignment, providing the misleading appearance that something is wrong with your garage motor.

There is a pair of sensors: one that sends a light beam and the other that receives it. Check to see whether the LED light is on or off in each one. If it is not glowing, the sensor assumes something is blocking it, which means it’s misaligned or blocked. Check that the two sensors are properly aligned and not blocked by cobwebs, dust, or other material.

You can bypass it by simply pressing the wall-mounted garage door switch (after ensuring sure it’s safe to lock the garage). If your door shuts smoothly, but nothing obstructs the sensors, it’s possible that the sensor is malfunctioning and not the door motor.

A garage motor problem may frequently be traced back to the remote control, which may be fixed by simply replacing the battery. If replacing the battery doesn’t work, climb a ladder and push and hold the motors unit’s “learn” switch.

  1. Keypad

You may also check the battery in the wall-mounted keypad. Despite its prominent positioning on the wall, it’s easy to forget that it’s powered by batteries affecting the performance of the motor.
