In newer openers, safety sensors may also be the culprit. Safety sensors work in pairs, mounted on either side of the garage door at about 10 to 12 inches in height. Each beams a light – one red, one green – across the opening. When the beam is obstructed or when the sensors cannot catch the other sensor’s light, the garage door opener will fail to engage or, sometimes, stop during operation. The fix is simple: Check for anything obstructing the sensors. Remove obstacles, position the sensors directly across from each other, or clean the sensor’s surface to remove moisture, dirt or other impediments. Afterwards, attempt to open the garage door again. If you’re successful, you know that the problem is resolved.

Finally, move to the house breaker or fuse box and check the circuit controlling the door opener. Reset a tripped breaker – which will be out of line with the other breakers, looking half on and half off – or replace the fuse. Even if the breaker looks fine, try turning it off, waiting about 60 seconds, then turning it on again to reset the connection. Consult an electrician for damaged wiring in the breaker, fuse box, or in the home’s wiring.

If the remote works fine but the wall unit fails to engage the opener, first consider the power source. Some opener wall control units are battery operated while others tie into your home’s electrical wiring or simply plug into the wall. Test the batteries, if applicable, to see if that fixes the problem. Otherwise, quickly examine the plug or wiring to see if you can locate visible damage such as scorched, exposed or broken wires.

Check to see if either the car remote or wall unit will activate the garage door opener first. As simple as it seems, in many cases that first panicked, “Oh my goodness it isn’t working!” is followed by the realization that the remote batteries are simply weak or dead. Incidentally, many remotes feature a blinking LED light that may actually flash to display a code which diagnoses operational problems. Consult your owner’s manual for more information.
