“Texas leads the nation in power outages, with Houston among the top cities impacted.” Power failures are more than just an inconvenience here—they’re a regular part of life, especially during storm season. And while a few hours without electricity might be a minor hiccup for your home’s lights or appliances, it can leave your garage door stuck shut when you need it most.

Your garage door opener is more vulnerable than you think. A sudden power surge can fry the logic board, and a total outage can trap your car inside. Let’s talk about why a battery backup for your garage door opener isn’t just a luxury, it’s a necessity in Houston—and how power surges can sabotage your system if you’re not prepared.

What’s a Garage Door Opener Battery Backup?

A backup battery ensures your garage door will open and close during times of power outages, More specifically, it is a small, 12-volt battery unit that has stored power that is used to open and close the garage door when a power outage occurs. Many brands of door openers currently provide this battery backup option directly on their openers. Here are a few Liftmaster garage door openers with battery backup:

When Is it Time to Change the Backup Battery?

Depending on the backup battery model you use in your garage door opener, you’ll hear a beep every 20 or 30 seconds in addition to seeing an orange or red light indicating the state of the battery. We recommend looking it up on your garage door opener manufacturer’s website for exact instructions on what you should do and when, and follow them closely.

What Other Ways Are There to Open the Garage Door?

If you have an older model garage door opener or opted to by one without the battery backup option, your only other option during a power outage is to open the garage door manually. You have to pull down on the red emergency release cord on the door opener which disengages the trolley, manually lift the door, move your car out of the garage, then close the door and reengage the trolley by reconnecting it to the release mechanism. Reconnecting the release mechanism is vitally important because if not done, your garage becomes vulnerable, as it can be easily lifted and closed by anyone. An alternative to reengaging the trolly is a sidelock that can be installed on the inside of the door in the second section. By pushing the steel bar on the lock into the vertical track, you’ll lock your door so that no one can enter.

One Last Note: Your Garage Door Opener Logic Board

There are times here in Houston we have a power surge. That power surge or the surge after a power outage can cause problems with the garage door opener logic board. If the motor unit has power but won’t respond to any remote or the wall control, the logic control board could be the problem. Unplug the garage door opener and check the wiring connections on the panel. If the wiring connections are okay, wait a few minutes before plugging the garage door opener back in. Disconnecting the power resets the logic board after a power outage or surge. Then test whether the opener works. If not, you’ll likely need to replace the logic board
