Garage Door Sensors Not Working? Here’s How To Fix 

Here are 6 steps on how to fix garage door sensors that are not working:

Check the alignment of the sensors. The sensors should be aligned so that the infrared beam from one unit is received by the other.

Clean the sensors. Dust and dirt can build up on the sensors and interfere with their ability to function properly.

Check the wiring. The wires that connect the sensors to the garage door opener can become damaged or disconnected.

Reset the sensors. Sometimes, the sensors can be reset by turning off the power to the garage door opener for a few minutes and then turning it back on.

Check the safety settings. The safety settings on the garage door opener may need to be adjusted. Consult the owner's manual for instructions on how to adjust the safety settings.

Call a professional. If you have tried all of the above and the garage door sensors are still not working, you may need to call a professional garage door repair technician.
