Winter storms, falling trees, and planned power shutoffs leave parts of Santa Cruz County in the dark every year, from the San Lorenzo Valley to Aptos and Watsonville. When the power goes, so does the garage door opener, and plenty of people find out the hard way that they have never used the manual release.

Here is how to open the door safely during an outage, how to get the opener working again once power is back, and how to tell when the outage left real damage behind.

During the outage: opening the door by hand

  1. Close the door first, if it is not already closed. The release is safest to use with the door down. If the door is stuck open, see the note below.
  2. Pull the red release cord. It hangs from the trolley on the opener rail. Pull it straight down, or down and back toward the motor, depending on the model. That disconnects the door from the opener.
  3. Lift the door from the bottom handle or the bottom section. A door with healthy springs lifts with modest effort and stays near halfway when you let go. Keep your fingers out of the section joints.
  4. Lift it all the way up and make sure it stays. If it starts to drift down, hold it and lower it slowly.
  5. Lock it when you close it. With the opener disconnected, the door is not locked. Use the side slide lock if the door has one, or keep the house door locked.

Important: if the door feels extremely heavy, rises crooked, or will not stay up, a spring or cable is broken. Stop and leave it down. Lifting a door with a broken spring is how people get hurt, and the opener was likely struggling with it before the outage anyway.

If the door is stuck open when the power goes out, do not pull the release unless someone can hold the door. Once disconnected, a door that is out of balance can drop. Lower it by hand with a helper, or leave it open and lock the door into the house.

When the power comes back

1. Reconnect the opener

On most openers, you can simply run the opener: the trolley travels along the rail and clicks back onto the door. On some models you pull the release cord toward the door to re-arm it first. Stand clear and watch the first cycle.

2. Check the wall button for a lock mode

Many LiftMaster and Chamberlain wall consoles have a lock or vacation button that disables remotes. People bump it while fumbling in the dark. If the wall button works but the remotes do not, check for a lock light and turn it off.

3. Test the remotes and keypad

Most openers keep remote programming through a power loss. If a remote stopped working, replace its battery first, then reprogram it using the learn button on the motor head.

4. Watch a full cycle

Make sure the door opens fully, closes fully, and does not reverse at the floor. If the door stops short or reverses, the safety sensors may have been knocked out of line, or the travel limits may need a reset.

Signs the outage damaged something

Power surges when the grid comes back can hurt openers, especially older units. Call for service if:

  • The opener has no lights and no response, but the outlet works (test it with a lamp).
  • The opener light blinks in a pattern, or the motor clicks and does not run.
  • The sensor lights stay dark even after you clean and align them.
  • The motor hums but the door does not move. That can be a stripped gear, or a broken spring that happened during the outage.

Before you call, check the breaker and any GFCI outlet in the garage. A tripped GFCI is a common, free fix.

Battery backup openers

California has required battery backup on new residential garage door openers since July 1, 2019. If your opener was installed before then, it probably does not have one. A battery backup unit runs the door for a limited number of cycles during an outage, which matters most when you need to get a car out for an evacuation or a hospital trip.

Backup batteries wear out over time. Most units beep or show a light when the battery is weak. If yours is chirping, replace the battery rather than unplugging it.

If your opener is older and you want backup, we can tell you whether a battery can be added to your model or whether a new opener makes more sense. See our garage door opener repair in Santa Cruz page for what we check.

Before the next storm

  • Practice using the release cord once with the power on, so you know how it works.
  • Check that the door is balanced: it should stay near halfway when lifted by hand.
  • Plug the opener into a surge protector rated for motors, or ask an electrician about whole-home surge protection.
  • Keep a flashlight where you can reach it from the garage door.
