Garage Door Won’t Close After Power Outage? (Fix It Now!)


Garage Door Won’t Close After Power Outage

Power outages are always frustrating for the homeowner. However, they can also cause more than just inconvenience. When the power surges, it can leave your garage stuck open and your belongings vulnerable.

If the garage door doesn’t close after a power outage, first look around for any visual issues. If you don’t see any, you need to reset the garage door.

How Does a Power Outage Affect the Garage Door?

During a thunderstorm, lightning can be very damaging. Lightning doesn’t have to hit the house directly to cause damage. The electricity from the lightning can destroy any electric appliances in the home and even start fires. 

If lightning strikes your garage during a power outage, you need to address the issue as soon as possible.

How to Reconnect the Garage Door After a Power Outage

If the garage door doesn’t open or close after a power outage, you will need to reconnect the garage. 

Follow the steps below to reconnect the garage door.

Step 1: Disconnect Power from the Garage Door Opener. If the garage door is closed, unplug the automatic garage door opener.

Step 2: Disconnect the Garage Door Opener from the Door. To disconnect the garage door opener from the door, pull the emergency cord. It should have a red handle and hang down in the center of the garage door motor. 

Step 3: Manually Lift the Garage Door. Manually lift the garage door until you completely open it. If the door is balanced correctly, it will stay in place while open. However, if the door is difficult to open, contact a professional to prevent further damage to the door.

Step 4: Manually Close the Garage Door. Manually close the garage door and lock it. When you manually slide the lock bar, you will securely shut the garage.

Step 5: Reconnect the Garage Door. Once you have restored power, reconnect the garage door opener. Make sure that you first unlock the door before you reconnect the opener. If you attempt to open the garage door while locked, it can cause serious damage.

If your garage door does not function after a power outage, you will need to put it in bypass mode.

Ways to Put the Garage Door in Bypass Mode

If your garage door gets damaged after a storm or power outage, you will need to put it into bypass mode. This prevents further damage to the door until a garage door technician can service it.

There are several ways to put the garage door into bypass mode.

Method 1: Set the Door to Manual Mode

Set the door to manual mode to prevent the garage door from falling if opened.

Materials You Will Need:

  • Two 2 x 4 wood planks
  • A helping hand 
  • Hammer 

Step 1: Double-Check That the Garage Door Is Closed. First, ensure that you have closed the garage door. If you set the door to manual mode while the garage door is open, it can abruptly fall. However, if you cannot close the garage because of a stuck door, move on to the next step.

Step 2: Prop Open the Garage Door. Use two 2 x 4 pieces of wood to prop up the garage door if it’s stuck open. The 2 x 4s should be as tall as the garage door opening. Use a hammer to tap the planks into place between the garage door and floor on either side. 

If the garage door has a damaged spring, the planks will prevent the door from slamming shut.

Step 3: Pull the Door’s Manual Release Cord. Pull down on the manual release cord located next to the garage door motor. The cord will disconnect the trolley from the automatic garage door opener. Once you do this, it will allow you to open and close the garage door manually.

Step 4: Remove the 2 x 4 Planks and Close the Garage Door. Remove the 2 x 4 planks and manually close the door. This will require a helping hand. You can remove the planks while someone else holds the door. 

Once you remove the wood, carefully lower the garage door to the closed position.

Step 5: Pull the Cord to Open the Garage Door. To open the garage door, pull the cord toward the garage door motor. Pull the cord down and toward the motor when opening the door to prevent the cord from getting stuck. You may also require a helping hand for this step.

Step 6: Set the Garage Door Back to Automatic Mode. Set the garage door back to automatic mode by pulling the manual release cord toward the door opening. While you do this, you will need to open the garage door simultaneously. This should reconnect the trolley to the automatic opener.

The garage door should now automatically open and close with the remote.

Method 2: Disconnect the Garage Door Sensors

Another way to put the garage door in bypass mode is to disconnect the garage door sensors.

Materials You Will Need:

  • Wire cutters 

Step 1: Turn Off the Power. Disconnect the garage door from the power.  Flip the circuit that controls the garage, or unplug it from the wall.

Step 2: Locate the Garage Door Sensors. You can find the garage door sensors on each side of the door. The sensors are toward the floor near the opening.

Step 3: Remove the Sensors from the Brackets. Remove the sensors from the brackets by loosening the wing nut. You can find the wing nut on the side of the sensor. Rotate the wing nut clockwise to loosen, freeing the sensors from the brackets.

Step 4: Cut the Wires from the Safety Sensor. Using a wire cutter, cut the black and white sensor wire about 1 inch from the sensor. If done correctly, this will disconnect the safety sensors from the garage door.

Step 5: Reattach the Cut Wires to the New Sensors. When you are ready to turn the sensors back on, reattach the cut wires to the new sensors. Strip the ends of the wires you cut to expose the metal. Twist the black wire that you previously cut to the black wire coming out of the new sensor.

Do the same thing with the white wire, then secure the sensors and their brackets and tighten the wing nuts.

Other Garage Door Problems

Garage doors often come with a host of other issues, too, no matter the model.

Garage Door Opener Doesn’t Work

If you attempt to open the garage door with the remote and there is no response, check the power source. Make sure to plug in the automatic opener and ensure there are no tripped breakers or blown fuses. If you have a battery-operated system, place the battery in the automatic opener and the remote.

Then, if this doesn’t solve the problem, check that the disconnect switch is connected. If it is not connected, it will prevent the door from opening in case of an emergency. Therefore,  plug the cord back in then attempt to open the garage again.

Garage Door Will Not Stay Closed

If the garage door does not stay closed, you could have an issue with the safety sensors. The safety sensors automatically reverse the door if there is something in the way or an obstruction in the track. Clean the sensors and tracks to make sure there is no debris.

Another reason the door may not stay closed is that the open and close limits are off-kilter. If the close limit causes the door to lower further than necessary, it will hit the ground and reverse. It does this because it assumes there’s an object blocking the way of closing completely. 

Reference your owner’s manual to determine the open and close limits as well as directions on how to reset them.

Garage Door Will Not Stay Open

If the garage door slides down the tracks after it has opened, the track could be misaligned. The alignment gives the door enough space for the weight to drag the door closed again.

Garage Doors Makes Noises While Opening and Closing

If the garage door is particularly noisy when opening and closing, there may be an issue with the spring mechanisms. For example, there might be broken or incorrectly connected tension springs. 

Therefore, the opening system won’t have enough strength to handle the door’s weight, causing a loud screech. Contact a professional to examine the springs to determine their condition. 

If you hear a squealing noise while the garage door opens, the tracks may need to be lubricated. Additionally, this could also be a sign of misaligned tracks or rusted rollers. If this is the issue, you need to replace the tracks.
