Garage Door Problem Guide
Garage Door Won’t Open in a Power Outage
Storms and outages happen. Here’s how to open the door manually — safely — and how to avoid getting stuck next time.
Quick answer
Without power, an opener can’t move the door unless it has a battery backup. To open it by hand, pull the red emergency release cord with the door fully closed to disconnect it from the opener, then lift the door by hand. Only do this if the springs and cables are intact and the door feels light enough to lift.
Safety first: Don’t pull the emergency release with the door partly open — it can fall. Don’t lift a door by hand if a spring is broken or a cable is loose.
How to open the door manually
- Make sure the door is fully closed.
- Look up at the springs and cables. If anything looks broken, stop — the door may be too heavy.
- Pull the red emergency release cord down (and toward the door on some models) to disconnect the trolley.
- Lift the door by the handle or bottom section with straight legs. It should feel manageable.
- Lift it fully open so it stays in place. If it won’t stay open, hold it and lower it carefully.
- Lock the door manually or keep the interior door locked while the opener is disconnected.
Reconnecting after power returns
Many openers reconnect automatically when you run the opener — the trolley catches the carriage. Some require pulling the release cord toward the motor or resetting a lever. Check your manual. Then test the door and safety reverse.
What not to do
- Don’t pull the release with the door open or halfway.
- Don’t leave the door unlocked and disconnected overnight.
- Don’t lift a door that feels extremely heavy.
If the door is very hard to lift by hand, that’s a sign the springs need attention even when the power is on. See door feels heavy to lift.
Not comfortable checking this yourself?
Call and a technician can diagnose the door safely and explain the repair options.
Avoid getting stuck next time
- Battery backup openers can run the door for a number of cycles during an outage — handy during summer storms.
- Keep a house key handy if the garage is your main entrance.
- Practice using the emergency release once when power is on, so you know how it works.
- If the release cord is missing or doesn’t work, have it fixed.

Frequently Asked Questions
How do I open my garage door when the power is out?
With the door fully closed, pull the red emergency release cord and lift the door by hand — as long as the springs and cables are intact.

Usually by running the opener until the trolley re-engages. Some models need the release pulled toward the motor. Check the manual.
Why is my door so heavy to lift by hand?
The springs may be weak or broken. Don’t force it — call for service.

Usually not, but if remotes stop working, reprogram them using the learn button.
