Introduction
Having a garage door that won’t close can be frustrating and inconvenient. One common issue is when the garage door starts blinking and fails to close properly. This article will provide you with some troubleshooting tips to help you resolve this issue and get your garage door back to working condition.
Check the Safety Sensors
One of the primary reasons why your garage door might be blinking and not closing is due to a malfunctioning safety sensor. These sensors are located near the bottom of the door on each side and send an invisible beam across the opening. If something interrupts this beam, the door won’t close. Check if the sensors are aligned properly and clean any obstructions or dirt that may be blocking the path.
Inspect the Garage Door Opener
Another possible cause for the blinking issue is a problem with the garage door opener itself. Start by checking the batteries in the remote control to ensure they are not depleted. If the batteries are fine, inspect the opener for any loose wires or damaged components. It’s also a good idea to reset the opener by unplugging it from the power source for a few minutes and then plugging it back in.
Examine the Garage Door Springs
Garage door springs play a crucial role in the smooth operation of the door. If one or both of the springs are broken or damaged, it can prevent the door from closing properly. Look for signs of wear and tear on the springs, such as rust or gaps. If you suspect a problem with the springs, it’s best to seek assistance from a professional garage door technician.
Check for Obstructions
Obstructions in the garage door’s path can also cause the blinking issue. Inspect the tracks and rollers for any debris or objects that may be blocking the door’s movement. Clear away any obstructions and ensure that the door can move freely along the tracks.
Verify the Door’s Travel Limits
Garage doors have travel limits that determine how far they should open and close. If these limits are not properly set, the door may stop halfway and start blinking. Consult your garage door opener’s manual to learn how to adjust the travel limits. This process typically involves pressing specific buttons or turning knobs on the opener.
Reset the Garage Door Opener
If none of the above troubleshooting tips work, you can try resetting the garage door opener. Locate the reset button on the opener and press it for a few seconds. This will clear any previous programming and restore the opener to its default settings. After resetting, try operating the door again to see if the blinking issue persists.
Consult a Professional
If you’ve exhausted all the troubleshooting steps and your garage door still won’t close and continues to blink, it’s time to call a professional garage door technician. They have the expertise and tools to diagnose and fix complex issues that may be causing the problem. It’s always better to seek professional assistance rather than attempting complex repairs on your own.
Conclusion
A garage door that won’t close and keeps blinking can be a sign of various underlying issues. By following the troubleshooting tips mentioned in this article, you can identify and resolve common problems associated with a malfunctioning garage door. Remember to prioritize safety and seek professional help if needed to ensure proper functioning and longevity of your garage door.
