How to Spot and Troubleshoot Common Garage Door Problems

by | Oct 14, 2021

Your garage door opens and closes approximately 1,500 times a year. With a weight exceeding 150 pounds, it can put a lot of pressure on the underlying mechanism. In this article, you’ll find tips on how to troubleshoot and fix your garage door.

Your Garage Door Won’t Open or Close

When the garage door does not open or close, troubleshoot the opener first. You can start by checking the condition of the batteries and replace them if they are dead. You can locate the batteries at the back of the transmitter.

It may also not be a fault from your transmitter but simply that you are merely out of range. The range for most transmitters is about four or five car lengths, or 50 feet, from the opener. Moving closer should get the door to open.

There could be barriers preventing the transmitter on the garage door from receiving the signal. When looking for obstructions, also make a point of checking for any signs of damage and schedule repairs if necessary.

It is also possible that the motor is defective. In that case, you should consult a repair technician to diagnose the garage door. Consider talking to Garage Door Doctor’s team for prompt garage door repairs in anywhere in or around Indianapolis.

Garage Door Opens but Does Not Close

If the garage door opens but does not close completely, the most probable cause is a faulty safety sensor. The photo eye sensors are usually on either side of the door. These devices prevent it from closing when there is an obstruction.

Start by examining the photo-eye sensors and ensure their alignment is correct. The easiest way to check for problems is to measure the height of the sensors. The distance from the floor should be the same for both if the alignment is correct.

Besides misalignment, another issue is dust on the lens. You can use a microfiber cloth to wipe off the grime and dust while taking care not to scratch the surface.

After cleaning and aligning the photo-eye sensors, test the door. If the door does not close, it may be a fault in another part of your system. You can call a garage door technician to troubleshoot and fix the opener.

Door Closes but Immediately Opens

If the door closes and then opens, it is probably an issue with the limit switch settings. It can happen when you have a new garage door installation or an old model that needs a reboot to work correctly.

The limit switch settings signal the door how far to move when closing. If the range is set too high, it will close and open again. The opener will conclude that something is obstructing the door and will initiate the safety mechanism.

The dials for the limit switch settings can vary depending on the model of your opener. You can adjust the limit switch gradually by turning the dial in small increments. Keep turning the dial until the door stops after it closes. You can consult the opener’s manual for the location of the switch for your model.

Garage Door Opens Partially

If there is a problem with the limit switch adjustment, your garage door may fail to open completely. The door may rise before stopping halfway. Incorrect limit switch settings may signal the opener to stop before the door ascends to the top.

If adjusting the limit switch does not solve the problem, the rollers could be a cause. The rollers might need lubrication, or they may be defective and require a replacement.

Another source of the problem might be a warped metal track. For the door to open and close properly, the alignment must be precise. Otherwise, it will open and close unevenly. With time, the problem will become worse as the heavy garage door moves along the defective tracks.

You will need a level to check if the alignment is correct. Typically, there will be rubbing sounds as the door moves past the point where the tracks have warped. You can unscrew the tracks and use a rubber mallet to push them back into position gently.

If it gets to the point where the door does not open at all, the damage may be too severe to fix. In such situations, you should consult a garage door professional. Garage Door Doctor has the knowledge and expertise to repair your garage door for you.

The Motor Is Running, but the Door Does Not Move

Sometimes, the motor will continue running, but the door does not move at all. In such instances, it could either be an issue with the limit switch or the belt.

If the issue is with the limit settings, the door may close while the motor keeps running. Most often, this is an installation problem. An adjustment of the switch should fix it.

If the motor is still running, it could also be an issue with the trolley. It often happens when someone pulls the emergency release rope. Pulling it upwards and towards the opener should re-engage the motor. You can consult the manufacturer’s manual for specific instructions for your model.

If none of the solutions work, it could be a fault with the system. It is possible that the gears are worn out and cannot engage the motor properly. The emergency release rope may have gotten stuck. In either case, a professional should diagnose and repair your system.

Troubleshooting Unusual Sounds

If you have a noisy garage door, it is often an indication of a fault in the system. A vibrating sound when opening or closing indicates the nuts and bolts are loose. A high-pitched squealing noise is a sign of defective hinges. Squeaking can also indicate friction due to a lack of lubrication.

Banging and rattling noises are usually an issue with the door’s balance. You may also notice that it takes time for the door to open and close or that the movement is irregular. Ignoring the problem may damage the spring and cable assembly.

One of the sounds you should never overlook is a loud banging noise. You may hear this when the torsion springs break while you are at home. The springs have a lifespan of 10,000 cycles and may give in when they exceed their limit.

A broken spring can be dangerous to occupants of your home. Torsion springs also support the door’s cables. If you don’t address the issue in a timely fashion, these will also break. That’s why a prompt repair is crucial to avoid unnecessary expenses.

Tips for Preventing Garage Door Problems

Whenever you detect a technical problem, you should schedule repairs as soon as possible. You can troubleshoot and fix issues with the settings or alignment of the sensors. If components of the system are defective, however, you risk serious injury.

Approximately 30,000 people each year report sustaining injuries when trying to fix a garage door. You can prevent faults in the future by scheduling maintenance services at least every 18 months. Maintenance helps you save on repair costs while reducing the risk of accidents in your home.
