If you are wondering why your garage door opener only works sometimes, there could only be two likely reasons. It’s either the battery in your remote is dying or low at voltage or one of your neighbors might be using the same wave frequency as your door. Below are some ways on how you can resolve this issue.
• Replace the batteries in your remotes. Same goes with your exterior keypad if you have one. Take the time to check your battery terminal and connectors too and make sure no corrosion has built up. Replace them if needed.
• Other factors that can cause interference and can prevent your door opener from responding to the signal from your remote are noisy gadget chargers plugged near your garage door and radio transmitters. This issue can be fixed by simply changing one of the code buttons on your remote.
If the problem is not straightened out with the steps provided, seek help from a garage door repair expert.
