Common Reasons Why Your Garage Door Opener Isn't Working
Garage door openers are a very handy way to get in and out of the garage, but they do have their share of problems. Most of them are mechanical in nature, but they can also be electrical or electronic. Here are some common reasons why a garage door opener won't open:
Check your batteries
If you have an older model, it's possible that your battery has died. Try replacing the old battery with a new one if this is the case.
Check your power
Most modern garage door opener systems are hardwired into your electrical system. Check your breaker box, and ensure that the power to your garage isn't off. Your power could have been tripped off in your garage but still, be on in the rest of your home.
Check for loose wires or connectors
If the wires are loose or disconnected from their contacts, then this could be why your opener won't work properly. Check all of them and make sure they are properly connected to their terminals on the motor assembly as well as at both ends of the circuit wiring harnesses.
Check for jammed sensors or limit switches
The sensors on your door need to close properly in order for it to open and close automatically. If they don't close all the way due to a foreign object being stuck in them (such as dirt), then they won't function correctly and your opener won't work either.
Consider Signal Interference
The signal from the remote isn't reaching the receiver at the other end of your system (usually mounted under the door bracket). Make sure nothing (like insulation) is blocking the signal path between the buttons on your remote and their respective receivers inside your garage door opener carriage unit; this is more likely to happen if people leave them.
The limit switches keep tabs on how far up or down your garage door goes before stopping at its destination so that they don't ever go beyond their limits (which could cause serious damage). If these are broken, your garage door opener will not work properly.
There are many reasons why your garage door opener will not work properly. If you are not able to troubleshoot why your garage door opener isn't working properly on your own, you are going to need to call in a garage door professional to assist you. They will be able to get to the root of the problem quickly, and get your garage door opening again, so you can freely move your vehicle in and out of your garage.
