Garage Door Openers Direct Drive – Pros & Cons
Why is my garage door opener light staying on?
The garage door light is staying on because the light switch may have been manually activated. The motion sensors are picking something up and the automatic light is being triggered or the switch at the panel has been left on.
Garage door lights are activated in several ways. When the door is opened or when it is being shut the light will come on to give you time to find your keys or get to the inside house door, all before the light goes out. There is nothing like being stuck in a dark garage fumbling to find the door or the light switch.
There are also motion detector sensors that can be activated when something is triggering them. Most sensors are ultrasonic and are activated by sound frequency. When the sound waves are disrupted then the sensors detect an obstruction. If they are malfunctioning they can continue to send a message to the opener to keep the light on.
Another possibility as to why your garage door light stays on is that you just might have forgotten to turn off the manual switch at the panel,
How to fix this
The best you can hope for is the light switch being left on and the worst is that the automatic sensors are malfunctioning or in need of replacing.
You can check the motion sensors from the control board by going through a series of tests. Follow the directions as they are given. If the diagnostics tests and the control board doesn’t reveal any abnormalities, the wiring might be what is causing the issue. How the wires are connected and where they are connected to the control board can cause the lights to stay on.
If you’re not comfortable with electrical wiring and don’t wish to mess with the control board then contacting a door professional would be advised.
