Safety sensors and remotes are small parts that cause big frustration. If your garage door keeps reversing before it closes, or your remote has stopped working, our technicians diagnose and fix the sensor, receiver board or remote coding — usually in a single short visit.
Common symptoms you'll see or hear
- ✔ Door goes down then immediately reverses back up
- ✔ Door only closes when you hold the wall button
- ✔ Sensor indicator light off or flashing
- ✔ Remote works only up close, or not at all
- ✔ Keypad not accepting your code
- ✔ New remotes won't program to the motor
Why this failure happens
Photo eye sensors sit low on the tracks where they're easily bumped by bins, bikes and brooms. Even slight misalignment, dust, cobwebs or direct sun on the lens can break the beam. Wiring damaged by rodents or impact is another common cause.
Remotes fail through flat batteries, worn buttons or lost coding, and receiver boards can be damaged by power surges.
How our technician repairs it on-site
We test the sensors, wiring and receiver, realign or replace photo eyes, repair wiring, and code new or existing remotes and keypads to your motor. We stock remotes for most major brands.
Every job finishes with a full safety reverse test so your door stops and reverses correctly. Upfront price approved on-site before we begin.
Frequently asked questions
Why does my garage door reverse before closing?
Most often a blocked or misaligned safety sensor. It can also be a force setting or track obstruction.
Can you supply replacement remotes?
Yes, we carry remotes for Merlin, B&D, ATA, Gliderol, Steel-Line and more.
Can sensors be bypassed?
No — sensors are an important safety feature. We repair them rather than bypass them.
