Understanding Garage Door Sensor Issues

Common Problems with Garage Door Sensors
Here’s what you might see:
1. The door reverses when closing. This usually means the sensors aren’t lined up right or are broken.
2. Sensors have blinking lights. That often shows there’s something blocking them or they’re out of sync.
Other stuff that can go wrong includes:
1. Sun interference on sensors causing them to mess up
2. Wiring problems that stop signals between parts
3. Photo-eyes not working at all, so the door won’t close.
If you notice any of these, fix them fast to keep things safe.
Garage Door Sensors Troubleshooting Steps
If your garage door sensors stop working, try these steps first:
1. Check sensor alignment: Make sure both photo-eyes face each other straight on. Bad alignment causes closing problems.
2. Look at wiring: Check for broken wires or loose spots that might mess things up.
3. Reset the sensors: Sometimes a simple reset fixes sensor logic and clears glitches.
Some common reasons for sensor troubles:
1. Something blocking the sensor path
2. Remote control signals not working right
3. Flashing lights on sensors showing errors
When to Call a Professional for Sensor Repair in Edmonton
Some sensor problems need an expert’s touch:

2. If you can’t get the sensors aligned or calibrated correctly by yourself.

Diagnosing the Problem and Finding the Solution
We start with careful garage door sensor diagnostics. Our skilled team tests everything using special tools. They look closely at wiring and sensor alignment. This helps find why lights blink or doors don’t close right. There is a diagnostic fee before work starts. That way, you know the cost upfront—no surprises. We explain what’s wrong in plain words. Then, we suggest fixes that won’t cost too much but will last.
Repair or Replacement
After we diagnose, we decide if repair or replacement fits best. Often, just realigning sensors fixes the problem cheaply. But sometimes parts are broken and must be replaced for safety. We use top-quality garage door sensor replacement parts with solid warranties. Every repair aims to last long so your automatic opener keeps working day after day.
Preventative Maintenance for Your Garage Door Sensors
Keeping sensors clean helps them work well all the time. Dust, dirt, spider webs, or other stuff on lenses can make them fail during daily use.
A good garage door preventive maintenance check looks for loose brackets or rust. It also checks wires for damage or wear.
Each year, a garage door safety inspection makes sure sensors meet UL 325 rules for automatic reversing doors. This keeps everyone around moving doors safe.
Hiring a pro to do maintenance helps get photo-eye sensor alignment just right every time you close your garage door safely.
