Step-by-Step Troubleshooting Guide
1. Check the Light Timer Setting
- Most Craftsman garage door openers allow you to set how long the light stays on.
- Access the control panel, locate the light timer adjustment, and set it to 1.5–4.5 minutes.
- If the light ignores the timer, move to the next step.
2. Inspect the Motion Sensor
Craftsman openers often come with built-in motion sensors. If the sensor is stuck detecting movement:
- Clean the sensor lens with a soft cloth.
- Ensure nothing is directly in front of the sensor.
- Test again by standing away from the opener for 5–10 minutes.
3. Reset the Garage Door Opener
- Unplug the opener from the power outlet.
- Wait at least 60 seconds.
- Plug it back in and test.
This can reset the internal relay controlling the light.
4. Test the Wall Switch and Remote
- A stuck wall switch may continuously send signals to keep the light on.
- Remove the wall switch from its mounting and check for dirt or shorted wires.
- Replace the batteries in your remote to rule out interference.
5. Inspect the Light Relay or Control Board
If none of the above steps fix the issue, the problem may lie in the opener’s internal parts.
- The light relay inside the opener can fail and stick in the “on” position.
- A damaged logic/control board may require professional repair or replacement.
