Troubleshooting a Garage Door Opener Remote Control
Believe it or not, technologies like garage door opener remote controls are supposed to make our lives easier. Unfortunately, there is nothing easy about having to open a garage door by hand in the middle of a freezing winter night because the remote for the opener won’t work. As technologies become more complex, there are more and more ways in which they can break down. Scan the list of problems below to find one that sounds familiar, then read the quick fix underneath it. Hopefully, it will help correct the error within the remote so that the garage will open and close without any issues.
The Garage Door Opener Remote Only Works Up Close
There are quite a few things that could cause this to happen. First, check the batteries within the remote itself to be sure they still carry a charge powerful enough to operate the remote. While replacing the batteries, be sure to clean the electrical contacts, since this may be another cause of a weak signal from the remote. If the remote is still only working up close it may be time to go talk to the neighbors. If a button is stuck on a neighbor's remote, the signal can cause an interference that may shorten the range of other radio frequency based devices in the area. Houses within the proximity of military bases will have this same problem and it is recommended that people in this situation switch to remotes that operate below 390 megahertz to fix the problem.
The Garage Door Remote Won’t Work but the Wall Switch Does
Check the batteries and electrical connections in the remote to make sure they are working correctly. If they are working correctly, the problem might be because of the safety sensors. Some garage doors have infrared sensors that shoot an invisible beam across the door. If one of these beams is misaligned, blocked or the lenses are dirty, then, as a safety feature, the opener will not allow the door to close unless the wall switch is held down. Clean the beam lenses, and make sure they are aligned and unobstructed. If this fails to fix the problem, unplug the door opener and then plug it back in. This will often reset the safety systems of the unit.
Remote Only Works in Cold or Warm Weather
If there are problems with the remote that seem to occur only when the weather is either cold or warm, the problem probably has to do with the infrared safety sensors that run along the bottom of the door. Next time it happens, try going inside the garage and holding down the wall switch to override the safety. If the door works when this is done, then it is indeed the sensors that need to be realigned. What happens when the weather turns, is that the steel which houses the sensors either expands or contracts which, in turn, will distort the path of the sensor beam. If the beam was slightly misaligned in the first place, then the slight change in the temperature of the metal will force the safety to kick in. Also, in cold climates with heated garages, the lens on the sensors can be clouded by either fogging or frosting. Clean the lenses and realign the sensors to fix the problem. If that doesn’t work try rebooting the unit by unplugging the opener and then plugging it back in.
The Batteries in the Remote are Brand New and the Door Still Won’t Open
If the remote is set to the correct frequency, then this may not be a remote problem, but rather a problem with the garage opener itself. Check to make sure that the opener is plugged in and that no fuses are blown or circuit breakers tripped. If the power seems to be working properly, there may be an internal problem with the opener's mechanisms. If this is the case, the unit will need to be taken in for service.
