Get Ready for Stormy Weather

Posted 5/23/2016

Lightning strikes and power surges can temporarily prevent your garage door opener from working or damage your opener permanently. See the tips below to prevent damage to your opener (motor) and what to do if your opener gets hit with a power surge:


  • Install a single outlet surge protector in the outlet that your opener is plugged into. You can order a LiftMaster surge protector online or we can order one for you. The LiftMaster model 990LM surge protector is designed specifically for use with LiftMaster garage door openers manufactured after 1994, and protects the entire garage door opener system, including the AC power line, door control panel, and safety reversing sensors. The surge protector provides a 5 year warranty from the date of purchase against power surge or lightning damage to your garage door opener system.

  • Though not always practical, you can always unplug your motor during thunder storms. 

  • Though some people exit and enter their home through the garage, it's always a good idea to take your house keys with you. This is so you can get into your house even when there is a power outage or other reason for your garage door to not open.

  • Replace your opener with a LiftMaster Model 8550W opener with battery backup and add a LIftMaster surge protector. 

After a Power Outage:

  • If your opener does not work after a power outage or surge, you can disengage your opener from the garage door by pulling the emergency release rope on most models. This will disengage the trolley from the rail and allow you to open your garage door manually. Only do this if your garage door is already closed; otherwise it may come crashing down.

  • Once you have power back on, but your opener still isn’t working, try unplugging it, then plugging it back in.

  • If your opener still isn’t working, you may have a fried circuit board that will need to be replaced. Killeen Overhead Doors stocks circuit boards for most common LiftMaster, Chamberlain and Craftsman brand openers. Just give us a call and let us know the model number and brand if you can. The model number can be found on the front of the motor behind the light cover. If you can’t see the model number, no worries. We’ll get you fixed up.
