ew things are more frustrating than a garage door that refuses to open—especially when you’re in a hurry. This is one of the most common issues homeowners face, and the causes can range from simple fixes to serious mechanical failures.

In this guide, we’ll walk you through the most common reasons your garage door won’t open and what you can do about it.

1. Dead Remote Batteries

Problem:

Solution:

• Try using the wall switch instead

👉 This is the simplest fix and solves the problem in many cases.

2. Misaligned or Blocked Sensors

Door starts to close, then reverses immediately.

Solution:

Problem:

Door won’t open, or opens only a few inches.

Signs:
