Step-by-Step Guide to Resetting Garage Door Opener Travel

The power flickers back on, your clocks are blinking "12:00," and you breathe a sigh of relief. But then you hit the button for your garage door, and it starts behaving strangely. It closes part-way and then reverses, or it stops short of the floor, leaving an annoying gap. If this sounds familiar, you're not alone.

This guide will walk you through every step, transforming you from a frustrated homeowner into a confident DIYer.
