Garages that cannot fully close are prone to security vulnerabilities, productivity disruptions, and threats to safety. As commercial garage doors are durable and heavy machines, you must promptly fix a door that won’t fully close. Use the following tips to keep your business secure and operating smoothly.
Look for Obstructions
Before calling in the professionals, begin by looking for obstructions preventing the garage door from closing. Debris, such as rocks, sticks, or even accumulated dust and dirt, can prevent the door from closing properly. They might sit at the base of the door or block various sensors that affect the door’s operation.
This simple interference can make a big difference. Clean the sensors and the bottom of the garage of all types of debris. If this doesn’t fix your problem, you know there’s a bigger issue.
Examine the Sensor Alignment
Misaligned sensors are common issues when dealing with a commercial garage door that won’t close. These safety sensors halt the closing process if something obstructs the door’s path, ensuring no harm comes to any object or person beneath it. However, if not properly aligned, they could signal an obstruction when there is none.
To check sensor alignment, look for the lights on the sensors. Most models have indicator lights that show whether the sensors are in alignment. A solid light typically indicates good alignment, while a blinking light suggests they’re misaligned. Adjust the sensors gently by hand until the indicator lights show they’re in the correct positions.
Evaluate the Power Supply
A consistent, uninterrupted power supply is crucial for the door’s operation. Begin by checking if you have the garage door opener properly plugged into an electrical outlet and whether the outlet is receiving power. You can quickly confirm this by plugging in another device to see if it works.
Additionally, inspect the circuit breaker or fuse box connected to the opener’s electrical circuit. A tripped circuit breaker or a blown fuse could be the reason the door opener isn’t operating.
Survey the Lubrication of Rollers and Hinges
Stiff rollers and hinges cause increased resistance as the door attempts to close. This added friction can make the door stop prematurely. Regularly applying a silicone-based lubricant or grease designed for garage doors can ensure these components move freely.
Check for Track Misalignment
If warehouse garage doors get stuck or emit a grinding and screeching sound, they may have misaligned tracks. Fix a commercial garage door that won’t close by beginning with a visual inspection. Minor misalignments are often fixable by gently tapping the tracks back into alignment using a hammer and a block of wood.
However, severe misalignments require professional assistance. The Door and Fence Store is a one-stop shop for garage door repair and maintenance. Our team of skilled technicians will conduct a thorough repair to ensure safe and reliable door operation.
