    Garage Door Opens By Itself

    Homeowners often report a peculiar phenomenon: their garage door opens by itself. This strange occurrence can be unsettling, not to mention inconvenient. In this blog post, we will delve into why this happens and how to fix it.

    Understanding the Self-Opening Garage Door

    A garage door that opens on its own might seem like a scene from a science fiction movie. However, there are several practical reasons behind this eerie behavior.

    Common Causes

    1. Interference: Similar frequency signals from nearby devices can trigger your door.
    2. Malfunctioning Remote: A faulty remote can send unintended signals.
    3. Wiring Issues: Short circuits in the wiring can cause erratic behavior.
    4. Limit Setting Problems: Incorrectly set limit switches may make the door reverse upon hitting the ground.
