Garage door openers can be frustrating. Here are some simple tips and common symptoms to keep in mind when you decide to tackle your garage door opener troubleshoot.

Tips for your garage door opener troubleshoot:

  • Start with the door. When the door is closed, pull up on your garage door’s emergency cord to release. Lift the garage door and observe if it closes and opens smoothly. If you experience any type of resistance or difficulty, the problem could lie within its tracks, springs, or rollers, rather than the garage door opener itself.

Symptom #1: Neither the Wall Switch Nor the Remote Control Engages the Garage Door

If the garage door doesn’t budge at all when the wall switch or the remote is pressed, it is almost entirely certain that a power source has in some way been disrupted.

This is one of the most common issues, and one of the simplest to fix; the motor unit which drives the garage door as been unplugged. It is a good idea to check this before you move onto to any additional troubleshooting steps.

Inspect the outlet the garage door is connected and ensure that the cord is plugged in all the way. Other possible issues could lie within a fuse, circuit breaker, or the GFCI controlling unit. If your circuit has tripped or burned out, you may have to call a professional for a garage door opener repair.

Symptom #2: The Wall Switch Works but the Keypad or Remote Control Does Not

When it comes issues with the mounted keypad or the remote control, there are several possible causes and solutions.

  • Check the batteries. Still nothing? You may need to call on a repair garage door opener or purchase a new remote and install a new receiver.
  • Move closer to the garage door. It is very possible that you are out of range.
  • Ensure that your motor unit’s antenna is pointing downwards and without damage.
  • Reprogram the keypad and remote control. Electronics are sensitive and it is possible that they have been tripped in some way and need to be reset.

Symptom #3: Garage Door Will Not Close Completely

If your garage door opener opens with ease but fails to close all of the way, there may be three common causes:

  1. Your close-limit switch needs to be adjusted. The set-limit is what instructs your garage door motor to stop running. If these settings are off it may attempt to open back up when you attempt to close it.
  2. Safety sensors may need realignment. If anything is blocking your garage door’s sightline, or if these electronic eyes are not correctly aligned, the door will fail in its decent.
  3. Perhaps less frequently, rollers that are damaged or rusted can cause the door to stop or reverse in its tracks. In some cases, lubricating your rollers can help correct these problems. If issues still persist, you may need to contact an expert to fix your garage door opener.

Symptom #4: The Remote Works but the Wall Switch Does Not

If you find that your wall switch is malfunctioning while your remote control seems to remain intact, your wall switch wires or the wall switch itself may need replacing.

To determine what isn’t performing, start by removing the wall switch and touching two pieces wire together. Don’t worry about these shocking you, as these wires are low voltage.

If you perform this test and the operator runs, you have determined that your switch needs replacing. If your operator fails to run during this test, the wire that connects to your switch is faulty.

Symptom #5: Garage Door Grinds, But Door Do Not Operate

If you notice that your garage door opener makes loud noises like it is grinding, but does not move, this is a telltale sign that your main drive gear has reached its end of life.

This is the most common malfunctioned component on a garage door opener. Replacing your main drive gear is a task best handled by a professional.

Symptom #6: Garage Door Opens, But the Motor Continues to Run

Although this problem is unusual, it has been known to happen from time to time. When this occurs, you typically need to move the up-limit switch away from the motor unit. This is something that is typically noticed immediately after installation.
