How to Replace Your Garage Door Opener Battery

Is Your Garage Door Opener Battery Dying?

The first step to resolving a garage door opener issue is determining if the problem lies with the battery. Here are some common signs of a failing battery:

  • Audible Warning: Listen for a distinctive warning tune emitted by the opener.
  • Manual Test: Unplug the opener and attempt to operate it manually. If it doesn’t work, the battery is likely the culprit.
  • Battery Life Indicator: Check the LED light on your wall control for indications of low battery power.
