What Causes a Faulty Commercial Garage Door?

Date:

When a rollup door is difficult to open or close, it indicates tight guides or excessive spring tension. Sometimes, it is difficult to identify the problem because the door is damaged, but a thorough inspection can reveal it. Broken or damaged tracks can also cause a malfunction, so check each element to find the root cause.

Torsion Springs

Torsion springs are responsible for lifting the door. If they are damaged, the door will be unable to lift fully. A faulty torsion spring may also trigger the safety features that prevent the door from lifting fully. This will cause a jerky movement and require an urgent commercial garage door repair. A broken spring will have different impacts depending on the design.

Commercial garage doors use torsion spring systems. These systems typically use one or two large, tightly wound springs. These springs are mounted on a header wall above the door. A three-pronged support system supports the springs of a center-bearing plate and two end-bearing plates.

If the springs fail to hold sufficient tension, they may separate. The springs should be lubricated at least bi-annually. This should be done in the fall when the temperature dips below freezing and at night when the temperature rises above 32 F (0 C). Use non-drip lithium base oil around the coils, wiping the oil off after application. Lubrication helps keep the springs in better shape and eliminates clinking noises.

Broken or Worn-Out Cable

A broken or worn-out cable will cause the door to lean or jam and may even trap a vehicle. This type of issue should be fixed as quickly as possible to prevent further damage. The first step to repairing a cable is to inspect it for kinks or fraying. This could indicate a larger problem. It is also important to remove any debris that is stuck in the cable.

One common cause of a faulty commercial garage door is a broken spring. If the spring breaks, it will cause the cable to fail, as it transfers the tension to the opposite side. It is also dangerous to open the door if the spring is broken. The remaining cable may snap, sending the door crashing to the floor or getting stuck halfway open.

The cable should be inspected every month to detect any issues. Checking for fraying or rust can signal that the cable needs to be replaced. Over time, rust can build up, creating weak spots and allowing the cable to break. It could snap if too corroded, damaging the door and anything underneath. The best thing to do is to call a professional to inspect the cable and ensure it’s in good condition.

Misaligned Photo Eyes

Misaligned photo eyes on a garage door are common problems. These issues can make the door appear off-track and cause a clicking sound and flashing lights. This problem can be a sign that a photo eye has become misaligned or has been bumped. To fix this, you should check the sensors and adjust them by hand. If dirty, wipe them down with a clean cloth and dry them.

The misaligned photo eyes are often caused by physical pressure or excessive use. The photo eyes must be installed at the same height to prevent misalignment. You can also put a cardboard box between the photo eyes and ensure that the door does not close when the box is in front.

Misaligned photo eyes on a garage door can also result in malfunctioning sensors. If the photo eyes are not functioning properly, the garage door cannot close. It is important to check the safety sensors periodically to ensure they do not interfere with the garage door. If the photo eyes are out of alignment, the garage door may reverse or stop altogether. If this happens, you must fix the problem before it damages the doors or the garage.

Insufficient Power Source

A faulty commercial garage door may be the result of insufficient power from an electrical source. It could be caused by a power line break or a wall switch. You can also check the wiring of the opener, if it is not damaged, to see if it is causing a problem.

A faulty commercial garage door may also result from a broken cable or spring. Broken cables can be dangerous since they can snap completely off track. Call a specialist who handles commercial garage door repairs if you are unsure how to fix the cables. Moreover, a broken spring is hazardous, especially if you have small children or pets.

A faulty sensor could also cause the door not to close properly. If the sensor is inoperative, it will blink or make noises. If you cannot close the garage door, the sensors are likely malfunctioning. Check the sensor wiring, which is usually visible on the back of the door. The sensor wires can become corroded over time due to exposure to weather conditions, pests, or other damage. It may be time to replace the sensor.
