Your commercial garage doors keep your business’s valuables safe. If you have a commercial garage door that won’t close securely, you are probably anxious to figure out why. Here are three reasons you might be having a problem:
Your safety sensors on your commercial garage door might not be working properly. Most garage doors have twin sensors at the bottom of the door, close to the ground. These two sensors face each other, and send a signal across the length of the doorway to tell whether there is anything in the way of the door as it closes. If either of these sensors isn’t receiving power or isn’t emitting their signal, your door won’t close all the way. This is annoying, but is actually a safety feature, as the sensors can’t tell if there’s anything in the way of the door. You can buy new sensors and replace the broken ones.
Sometimes, it might be that the sensors are working correctly, but are sending the wrong signal to the door, telling it that there is something in the way of it closing. This can happen if the sensors are misaligned. If one sensor is knocked and moved a little out of place, it can cause this problem. Most door sensors are equipped with a light that will tell you if the sensors are correctly aligned and working as they should. If the light is on and solid, then both your solids are functioning and aligned properly. If the light is blinking, this means that they have got out of alignment. You can fix this issue by putting the sensors back in the right place.
If your garage door seems to be stuck and is making a grinding noise when you try to close it, then it could be that the gears inside the openers have worn out and need to be replaced. Before you try to make the repair, you will have to disconnect the power supply and release the emergency catch. If you replace the gears and find that the door still won’t close properly, you can check the alignments of the door and the side tracks to look for other problems.
If you try these repairs and the door still won’t close, you may need to make some more adjustments to the door. Check the weatherstripping at the bottom of the door. The weatherstripping should be in close contact with the ground. If the door isn’t closing all the way, check and adjust the settings of the opener knob. One of the knobs is used to control the movement of the door and the other controls are used to control how far the door can open. Adjust this knob to lower the door properly, or it could go off track and end up wearing out.
Some commercial garage door problems can be fixed yourself, but some may need professional repairs to get the door working again. If you’re not sure what the problem is, call a professional so you don’t accidentally cause more damage.
