Garage Door Light Blinking And Not Closing

When your garage door light is blinking and not closing, it can be a frustrating and confusing problem. There are a few possible reasons why this might be happening, and it's important to troubleshoot the issue so that you can get your garage door working properly again.

1. Power Outage

One of the most common reasons why a garage door light might be blinking and not closing is a power outage. If there has been a power outage in your area, check to see if your other electrical appliances are working. If they are not, then the power outage is likely the cause of the problem. Once the power is restored, your garage door should start working again normally.

2. Loose Wiring

Another possible reason for a blinking garage door light is loose wiring. Over time, the wires that connect the garage door opener to the motor can become loose. This can cause the opener to malfunction, which can prevent the door from closing properly. To check for loose wiring, open the garage door opener and inspect the wires. If any of the wires are loose, tighten them using a screwdriver.

3. Faulty Sensor

Garage doors have sensors that help to prevent them from closing on people or objects. If one of these sensors is faulty, it can prevent the door from closing properly. To check for a faulty sensor, look for the sensors on the sides of the garage door opening. If either of the sensors is misaligned or damaged, it will need to be replaced.

4. Obstruction

If there is an obstruction in the path of the garage door, it will not be able to close properly. This obstruction could be anything from a car to a bicycle to a pile of boxes. Remove the obstruction and try closing the door again.

5. Broken Spring

Garage doors have springs that help to lift and lower the door. If one of these springs is broken, it can prevent the door from closing properly. To check for a broken spring, open the garage door and look for the springs. If one of the springs is broken, it will need to be replaced.

6. Faulty Motor

The motor is responsible for opening and closing the garage door. If the motor is faulty, it will not be able to close the door properly. To check for a faulty motor, listen for any strange noises coming from the motor. If the motor is making a grinding or squealing noise, it is likely faulty and will need to be replaced.

7. Circuit Board Failure

The circuit board is the brain of the garage door opener. If the circuit board fails, it can prevent the opener from working properly. To check for a faulty circuit board, look for any burnt or damaged components on the board. If the circuit board is damaged, it will need to be replaced.
