How to Fix a Broken Garage Door Sensor (Without Losing Your Mind)
Let’s be real—garage door sensors are like that one friend who’s mostly reliable but occasionally throws a tantrum for no reason. One minute your garage door works perfectly, and the next, it’s blinking angrily at you like a disco light. Frustrating? Absolutely. But before you start googling “garage door repair near me” in a panic, let’s walk through how to troubleshoot these finicky little devices. And hey, if DIY isn’t your thing (no shame—we’ve all been there), we’ll let you know when it’s time to call in the pros at Kald Gart Garage Doors here in Calgary.
First Things First: What’s a Garage Door Sensor Anyway?
Garage door sensors are those small, unassuming gadgets mounted near the bottom of your garage door tracks. Their job? To stop the door from closing if something—or someone—is in the way. Think of them as the overprotective parent of your garage door system. When they’re misaligned, dirty, or just plain broken, your door might refuse to close, reverse randomly, or flash its LED lights like it’s sending Morse code.
Pro Tip: If your door’s acting up, check the sensors before assuming you need a full garage door replacement. Nine times out of ten, it’s a quick fix!
Step 1: Clean the Sensors (Because Dust is the Enemy)
Let’s start simple. Over time, dirt, spiderwebs, or that mysterious garage grime can coat the sensor lenses, blocking the infrared beam. Here’s how to clean them:
- Unplug the garage door opener (safety first, folks).
- Wipe the lenses gently with a microfiber cloth.
- Avoid harsh chemicals—water or rubbing alcohol works fine.
- Plug the opener back in and test the door.
Still not working? Time to play detective.
Step 2: Check the Alignment (It’s Not You, It’s Them)
Garage door sensors work by “talking” to each other via an invisible beam. If they’re even slightly misaligned, that conversation turns into a shouting match. Here’s how to fix garage door track alignment for sensors:
- Look for the indicator lights. One sensor usually has a green light (power), and the other has amber (alignment status).
- If the amber light is off or blinking, gently adjust the sensor until both lights glow steady.
- Use a level to ensure they’re perfectly parallel.
FYI: If you’re sweating bullets trying to line these up, Kald Gart Garage Doors offers garage door track repair services that’ll save you the hassle. We’ve seen sensors more crooked than a Calgary snowdrift—trust us, it’s fixable.
Step 3: Inspect the Wiring (No, You Don’t Need a Degree in Electrical Engineering)
Loose or frayed wires are a common culprit. Trace the sensor wires back to the opener and check for:
- Exposed or chewed-up insulation (thanks, rodents).
- Loose connections at the terminal screws.
- Corrosion or rust (especially in humid garages).
Tighten any loose wires and replace damaged sections. Still nada? The sensor itself might be toast.

Common Garage Door Sensor Issues (and Solutions)
| Problem | Quick Fix | Call a Pro When… |
|---|---|---|
| Blinking LED lights | Clean lenses, check alignment | Lights stay off after adjustments |

“But Wait, What About the Cost?” (We’ve Got Answers)
Let’s address the elephant in the room: price. Sensor repairs are usually affordable—think $50–$150 for a service call. But if you’re also dealing with a broken spring, garage door cable repair, or commercial garage door repair, costs can add up. IMO, it’s worth investing in professional help to avoid turning a small issue into a “my garage door just fell off the tracks” disaster.
Kald Gart Garage Doors offers upfront pricing and same-day service. No hidden fees, no drama—just honest, reliable fixes.

Q: Can I bypass the sensors temporarily?

Q: Why does my sensor work sometimes but not others?
A: Loose wiring or power fluctuations. Let us tighten things up—literally.
Q: Are sensor issues common with older doors?
