1. Trouble In Closing The Garage Door
It is the first step to getting your goal. If the sensor is not working properly, the door will open without any difficulty, but the door wouldn’t close properly or only go halfway if you try to close the door. The door can get itself open again after closing it, and this is another problem.
2. Disrupted Power Supply
The power supply not being supplied inadequately might be one of the reasons why your garage door is not working properly. Sensor lights are a quick way to check if the power supply is disrupted or not. In case the green light goes on, it indicates that the supply of power is all right.
3. Damaged Sensor Wires
If the green light of the sensor doesn’t turn on, it may be due to the damaged wires of the sensor. The sensors work if the wires are intact and connected to the door opener of the garage. If the sensor starts blinking orange, it indicates that the wires are damaged as a warning sign.
4. Cleaning Issues
To make the sensors work and send signals ideally, they need cleaning. With the passage of time, dust and dirt accumulate over the sensors, or there might be spider webs or humidity, or even the pollution from car exhaust might affect the functionality of the sensors. All these are a great hindrance in sending the signals.
