How Lightning Storms Can Affect Your Garage Door Opener (and What to Do About It)
Living in Florida, lightning storms that roll in fast are just a part of life. But while they might seem like just another summer inconvenience, they can have a surprising impact on your home, especially your garage door opener.
Florida sees over 1.2 million lightning strikes per year, many of them during the peak summer storm season. If you've ever found your garage door acting strange after a storm, you're not alone. Let’s break down how lightning can affect your opener, what to watch for, and how to protect your system moving forward.
Why You Should Care: Lightning and Surge Risks
Power Surges from Nearby Strikes
Lightning doesn’t have to strike your home directly to do damage. When it hits near your property, the electrical current can travel through your home’s wiring, leading to sudden power surges. These spikes can fry the sensitive components inside your garage door opener, especially the logic board or motor. Once that goes, your garage no longer has a door, but an immovable object blocking the path.
Surges can also enter through low-voltage wiring connected to your photo, eye sensors, or wall control. Even if your outlet is grounded, these side routes can still send a damaging jolt straight to your opener’s circuit board.
At On Track Doors, we regularly inspect and repair openers damaged by lightning surges, making sure your system gets the professional care it needs after a storm.
Electromagnetic Interference (EMP)
Lightning also creates intense electromagnetic pulses (EMP). While less common than surge damage, these pulses can disrupt the wireless signal between your opener and remote, sometimes causing strange behavior like unresponsive remotes or spontaneous door movement. This typically only happens when lightning strikes very close by.
Common Signs of Lightning, Related Damage
Door opens or closes erratically
The remote or keypad stops working
Wall-mounted button is unresponsive
Sensors don’t light up or function properly
Visible damage to wiring or a burnt smell near the opener
Lights flash, but the door won’t move
If your system shows any of these signs after a storm, it’s worth investigating. Even if it seems minor, a small glitch today could mean a stuck garage door tomorrow.

Immediate Steps After a Storm
Check Power and Breakers
Start simple. Check that your garage door opener is plugged in, and reset any tripped breakers. If your outlet is dead, look for a GFCI reset button; many garage circuits are tied to a laundry room or bathroom GFCI outlet elsewhere in the house.
Try a Power Reset
Unplug the opener, wait about 30 seconds, then plug it back in. This can clear out any weird signals or glitches from a power surge.
Use the Manual Release
In a pinch? Pull the red emergency cord. It might not be high tech, but it gets the job done. Just don’t forget to re-engage it later, or you’ll be wondering why your door won’t budge.
Check the Diagnostic Light
Many modern openers have a small LED that flashes a pattern when something’s wrong. After a lightning strike or power surge, count the blinks and check your opener’s manual or manufacturer's website. For example, LiftMaster openers have detailed error code guides that you can follow.
Reprogram Keypads and Remotes
Power surges or interference may erase remote or keypad codes. If they're unresponsive but undamaged, try reprogramming them using the opener's manual instructions.
Know When to Call a Pro
If you suspect lightning damage to your opener, it’s also smart to consider the broader health of your garage system.
If basic troubleshooting doesn’t fix the problem, or if you notice signs of electrical damage, it’s time to call in a professional. Damaged circuit boards or motors usually need expert repair or replacement. This isn’t the place to test out your DIY skills unless you’ve got a background in electrical work and a lot of free weekends.
At On Track Doors, our experienced technicians can diagnose and repair lightning-damaged garage doors across Florida, keeping your home protected and your day moving.
How to Protect Your Garage Door Opener
Use a Dedicated Surge Protector
Install a surge protector rated for garage door openers. Some brands even offer plug-in surge protectors explicitly designed for them. On Track Doors can recommend models that work well with your existing system.
Consider Whole-Home Surge Protection
A whole-house surge suppressor adds another layer of defense by protecting all your home’s electrical systems. If you’re already replacing TVs and routers after every storm, this is a no-brainer.
Check Grounding and Use Lightning Rods
Make sure your home’s electrical system is grounded correctly. In lightning-prone areas like Florida, lightning rods can redirect strike energy safely into the ground, reducing risk to your home’s electronics. Not flashy, but effective.
Unplug Ahead of Severe Storms
If you know a storm is coming and your opener doesn’t have a battery backup, unplug it temporarily. It’s one of those “better safe than sorry” moves that can save you time, money, and frustration later.
Long-Term Reliability Tips
Install Battery Backup
Many modern openers come with battery backup systems, keeping your door functional during outages and preventing erratic behavior. Handy when the power’s out but your plans aren’t.
If your system doesn’t have one yet, On Track Doors offers battery backup installation for most major opener brands.
Schedule Regular Maintenance
Have your opener and sensors checked periodically to ensure everything’s working, and to catch minor issues before they turn into big problems. Think of it like a check, up for your garage.
With regular maintenance from On Track Doors, you’ll extend the life of your system and avoid costly breakdowns during storm season.
Replace Aging Units
If your opener is more than 10 to 15 years old and has been hit by a surge, consider a full replacement. Technology has come a long way; no sense hanging on to something that belongs in a museum.
We’ll help you choose the right model and handle professional installation from start to finish.
Final Thoughts
Florida’s stormy season can be rough on your home’s electronics, including your garage door system. But with the proper protection and a little preparation, you can keep your opener running smoothly all year long.
Pro tip: Some homeowner insurance policies or extended warranties may cover lightning-related electrical damage. It’s worth checking before you pay out of pocket.

Had the spring snap on my garage door. Called a few other companies that couldn’t make it out for over 5 days. Wade came out the next day and door was fixed in 30 mins. Fair price, honest guy… would highly recommend.
Torsion spring snapped on my garage door, I called several places for estimates, on track doors was the least expensive by over 50 dollars. Wade was the person who fixed my door, he is a very pleasant and very knowledgeable in his craft. Springs were changed within an hour and my door works perfect. Thanks Wade, i will always use you guys and will always refer you guys to all my friends and family.
I called at 7:15am this morning. They were here at 7:30am! Doesn’t get any better than that. Gentleman was very nice, very professional, interacted with my children who were I’m sure adding time to his job by answering their questions. Job was complete and he was done by 8:00am. VERY IMPRESSED. Will use On Track again in the future.
I would highly recommend On Track Doors. My garage door was off the track in the up position and was ready to fall down. They arrived and fixed the garage door within an hour and a half. Super service at a great price. No added fees for emergency or weekend work. Thanks!
I had him replace 3 garage doors with hurricane-impact garage doors; and I'm glad I trusted my intuition and used him to do the job. He was more than fair pricewise and his crew work was excellent. It was a pleasure doing business with him ;which is not an easy thing to say about contractors down here in Florida. He treats you like a customer. Your in good hands doing business with him.
