Was the Emergency Release Cord Pulled?

4

This is the #1 reason homeowners say, “My Garage Door Won’t Open After A Power Outage.”

During outages, many people pull the red emergency cord to open the door manually. When power returns, the opener won’t reconnect automatically.

How to Reconnect the Door

1. Make sure the door is fully closed.
2. Pull the emergency cord toward the door.
3. Move the door manually until you hear a click.
4. Press the opener button.

You should hear the trolley re-engage.

If the door feels heavy or won’t stay open manually, stop immediately — this may indicate a broken spring.

Could the Safety Sensors Be Blocking the Door?

Garage doors manufactured after 1993 include safety sensors near the floor.

If misaligned, the door won’t close or may not move at all.

Check for:

• Blinking sensor lights
• Obstructions
• Dirty lenses
• Loose wiring

Fix:

• Clean sensors with a dry cloth.
• Align both sensors until LED lights are solid.
• Tighten brackets.

This simple alignment solves many post-outage issues.

Is the Door Locked Manually?

Sometimes, during a blackout, someone locks the garage manually and forgets.

Check:

• Manual slide locks
• Side lock bars
• Padlocks

If engaged, unlock before trying the opener again.

How to Prevent This From Happening Again

Power outages are common in the U.S., especially during storms.

According to energy reliability data, the average American experiences 1–2 power outages per year, with storm-prone states seeing more.

Here’s how to prepare:

1. Install a Battery Backup

Modern openers offer battery backups that allow 20–50 cycles during outages.

2. Test Manual Release Twice Per Year

Prevent panic by practicing the release and reconnection process.

3. Replace Remote Batteries Annually

Small maintenance prevents unnecessary confusion.

4. Surge Protection

Install a surge protector to protect the opener circuit board.

• The door is crooked
• Springs appear broken

Garage door springs store enough force to lift 150–300 pounds. Repairs require specialized tools.
