Signs your opener needs repair
Not sure what you are dealing with? If any of these sound familiar, it is worth a diagnosis before it turns into a bigger repair.
The motor hums but the door won't move
Usually a stripped gear or a broken coupler between the motor and the rail.
The door reverses as soon as it touches the floor
A misaligned limit switch or a dirty, sun-blinded safety eye.
The remote only works up close
A failing logic board or antenna inside the unit, not the remote itself.
Grinding or screeching from the motor head
Worn gears, a dry rail or loose hardware that will only get worse.
Blinking error codes on the back panel
The opener has locked itself out after detecting a fault or force error.
App or Wi-Fi control keeps dropping
An outdated bridge or board that needs re-pairing or replacement.
How our opener repair works
Full diagnosis
We test the motor, capacitor, gears, travel limits, safety eyes and the door's balance as one system.
Written price first
You get an itemized quote before any work starts — repair, replace a part, or replace the unit entirely.
Repair on site
Most opener repairs are finished in 45 to 90 minutes with parts from our truck.
Test and program
We set the force and travel limits, verify the safety reverse, then program every remote and keypad.
What affects the price
Every job is quoted in writing before work begins, so you always know the total. These are the factors that move the number up or down.
- Drive type — belt, chain, screw or jackshaft
- Whether a single part, a gear kit, or the whole unit needs replacing
- Horsepower and the weight of your door
- Smart features and extra remotes or keypads
- Same-day versus after-hours scheduling
