Garage Door Troubleshooting Guide

Garage Door

If your garage door opener stops working properly, don’t be afraid. Garage openers are relatively simple machines and fixing them can be easy. Here are some common problems and solutions.

Your Wall Switch Doesn’t Work

If your garage door doesn’t move, check the power source. Check the outlet the motor is connected to and make sure the cord is plugged in.

It’s also possible that your circuit breaker has tripped or burned out. If you find other lights in the garage aren’t working, this is your likely culprit. You’ll need to reset the breaker or replace the burned-out fuse. If the circuit breaker is tripping repeatedly, it’s a sign that there’s a short circuit somewhere in the system.

The worst case scenario is your garage door opener’s motor has burned out. In this case, you’ll have to buy a replacement motor.

Your Remote Doesn’t Work

If your remote doesn’t work, try the following:

  • Replace your batteries.
  • Move closer to the door. It’s possible you are out of range of the antenna inside the garage.
  • Make sure the antenna on the motor unit is hanging correctly and not damaged.

Garage Door Doesn’t Close

If your garage door opens correctly but fails to close completely, there are two common reasons:

  • The close-limit switch needs adjusting. Your garage door has set-limit switches that tell the motor when to stop running. If the close-limit switch is set wrong, it will prevent the door from closing. The close-limit switch is usually a screw on the motor unit that you can adjust.
  • The safety sensors need adjustment. On the bottom of the door track on both sides are electronic eyes that require a clear line of sight between them. If anything blocks this sightline, the door won’t close properly. Make sure there’s nothing blocking the sight path between the electronic sensors and regularly clean any leaves or debris near your door.

Garage Door Goes in Reverse

There are two common problems that can cause a garage door to reverse before it touches the floor:

  • Garage door openers have an adjustment screw that controls closing force (the pressure a door is allowed to descend before the motor switches off). If a door reverses before it hits the floor, it’s because the close-force setting needs adjustment.

Damaged or rusted door rollers can create friction, making your door stop prematurely. Make sure your rollers are in good shape and regularly lubricated to prevent this.
