Check all the wiring from the unit to the sensors, the sensors themselves, make sure that dirt doesn’t obscure sensors lenses, and that they are properly aligned. If all these things check out and they still don’t work, it may be a damaged sensor. It is common, because they’re located near the floor, and are prone to dirt and water damage.
If all else fails, it might be a damaged circuit board in the power unit. These can become non-functional from a power surge, lightning strike or just old age.
Garage Door Opener FAQ
Our garage door opener will not do anything at all when we push the button. What should we look for first?
The first thing that you should verify is that the garage door opener plugged into the electric outlet.
Secondly, you should confirm that there is power coming out of the electrical outlet or plug the opener into another outlet with an extension cord. If there is power to the operator, then there is some type of mechanical or electrical problem within the garage door opener itself
and may need to be diagnosed by a qualified service technician
The light comes on but the garage door opener will not open or close the door. What should we look at first?
If the light on the garage door opener comes on, obviously the opener is getting power and the problem would be in the electrical or mechanical workings of the opener. Be sure to unplug
the operator before making any attempt to remove the motor head cover. To avoid the possibility
of electrical shock, why not have your garage door opener repair made by a knowledgeable service tech. If your garage door opener is more than ten years old you may want to consider replacing the garage door opener to one with the latest safety features.
Both of our transmitters quit working at the same time. Should we try changing the batteries in the remote controls?
Very seldom will the batteries in both transmitters go dead at the same time. Most likely the problem is in the radio receiver that is in the garage. It is also possible that the problem could be inside of the operator itself and that it is no longer sending power to the receiver unit. (On some openers the receiver and logic board are combined together on one solid state circuit board). It may be to your advantage to have a professional service call to determine the true problem.
