Control boards & wiring
We test the board, power and wiring with a meter, then repair or replace what failed.
Gate opener repair means diagnosing and fixing the motorized operator that moves your gate, not the gate itself: the control board, wiring, limits, safety sensors, backup batteries, gearbox and motor, plus the remotes and keypads that trigger it. Most failures trace back to a blocked sensor, a dead battery, a power problem or a gate that binds. Eagle Automatic Gate & Door repairs openers on every major brand, gives a written price before work starts, and tells you honestly when replacing makes more sense.

We carry common boards, sensors and batteries on the truck, so most repairs are done on the first visit.
If your opener is old, parts are gone or it keeps failing, a new LiftMaster with battery backup and modern safety sensors is often the better buy. We price both when it’s close.
“Half the opener calls we get could start with one quick check. The other half need a technician, and I’ll always tell you which is which.”
Often, yes. First check the breaker and the power switch on the operator, then look for anything blocking the photo eyes or the gate’s path. Many LiftMaster operators have a reset button; press it once, then try a remote. If the alarm keeps sounding, the gate reverses again, or you smell burning or hear grinding, stop there. Never prop a gate open by bypassing a sensor. Call our specialist and we’ll take it from there.

Still not sure? Call us and describe what your gate is doing.
Most operators beep and stop after repeated obstructions, a blocked or misaligned photo eye, or a low backup battery. Clear the path and reset; if it repeats, call us.
Usually a sensor is triggered, the force setting no longer matches the gate, or a timer-to-close setting is on. We diagnose and adjust it safely.
It depends on the cause and parts. We diagnose on site and give a written price before any work starts.
Yes. We repair LiftMaster and every other major opener brand.
Repair usually makes sense for newer openers with a single failed part. Old, unsupported or repeatedly failing openers are often better replaced; we price both.
Our work is backed by a parts and labor warranty, and LiftMaster equipment carries the manufacturer’s warranty.
