Alex was great to work with. Communication wise I didn't have to wait for answers to my questions, he worked with my time line and the quality of the work was great!
Technician on a ladder servicing a garage door opener rail inside an open garage
The remote clicks and nothing happens. The motor runs but the door doesn't go up. The door closes, then bounces back up like it hit something. We repair and replace garage door openers in Ottawa, and we start by working out whether the opener is the problem, because often it isn't.
Tell us what the opener is doing, send a photo of the unit on the ceiling and the label on its side, and call 613-265-3667 if you want to talk it through. We'll give you a flat-rate price to approve before we start.
Start with the door, not the motor
The opener is a guide, not a lifting machine. The springs carry the weight of the door, and the opener moves a door that is already balanced. If a spring has broken, the motor will hum and strain, and the gears can strip. Replacing the opener in that case fixes nothing. So our first check is whether the door itself lifts and balances properly. If it doesn't, the repair starts at the spring.
Common opener problems
Opener hums but the door won't move
Broken spring, stripped drive gear, or a disconnected trolley arm. We check which.
Door reverses before it closes
The safety sensors, mounted a few inches off the floor on each side of the door, are blocked or misaligned. Snow, a dirty lens, or a bumped bracket is enough. Sometimes the close travel is set too short and the door thinks it hit something.
Remote works only from a few feet away
Weak remote battery, a worn transmitter, or an antenna on the opener that's been knocked out of position. Cold makes weak batteries worse.
Wall button works, remote doesn't
The remote needs reprogramming or replacing, or the receiver has failed.
Opener stops partway or won't finish closing
Travel limits or force settings are out of adjustment, or the door is binding somewhere and the opener is giving up.
Light blinks, opener beeps, or the door doesn't respond
Many openers flash codes to report a sensor fault or a wiring problem. A photo of the unit helps us identify the model before we arrive.
Loud grinding or shaking
Dry or worn chain, a loose rail, or worn gears. It's worth acting on early, because a noisy opener that gets ignored often becomes a dead one.
Warning signs: stop using the opener
- The door doesn't reverse when something blocks it
- The door feels much heavier than it used to
- The opener strains, smokes or smells hot
- The door moves unevenly, or one side is lower than the other
- The sensors keep blinking and the door won't close. Don't tape over or bypass them.
Safety sensors and the reverse function exist to protect people, pets and cars. Don't bypass them. If the sensors are blocking the door from closing, we'll find out why and fix it.
How an opener repair works
- We test the door by hand to confirm it's balanced and moves freely.
- We inspect the opener, rail, trolley, drive, wiring, wall control and sensors.
- We identify the failed component: gear kit, circuit board, sensor, drive belt or chain, remote receiver, or the wiring.
- We tell you whether repair or replacement makes more sense, and give you a flat-rate price.
- After approval, we repair or replace the parts and reprogram remotes and keypads as needed.
- We adjust travel and force, test the reverse function, test the sensors, and cycle the door to confirm it works.
Repair or replace the opener?
A sensor, remote, wall button, or a worn gear or belt can often be repaired for less than the cost of a new unit. Replacement makes more sense when:
- The opener is well past 15 years old and parts are hard to find
- The circuit board or motor has failed
- It has no safety sensors, or the sensors are outdated
- It's very loud and you'd like a quieter belt-drive unit, especially if your bedroom is above the garage
- You want a keypad, smart controls or battery backup that your current unit can't support
Chain-drive openers are common and simple. Belt-drive units run quieter. Screw-drive units have fewer moving parts. We'll talk through which suits your door and your garage, and confirm the new opener is matched to the door's weight. If you're replacing the door as well, the opener choice belongs in the same conversation, so see garage door installation.
Cold-weather opener problems in Ottawa
Openers get moody when it's cold. Grease thickens and the motor works harder. Remote batteries lose strength, so a remote that works in September gives up at minus 20. Ice at the bottom edge glues the seal to the floor, and the opener pulls against it and stops, or reverses. Meltwater from the car can freeze on the photo-eye lenses and trip the sensors. If your door is slow in the cold, the cause may be the door's balance, not the opener, so we check both.
Power outages are the other winter trouble. Most openers have a manual release, but use it only with the door fully closed. A door that is open with a bad spring can fall when released.
Residential and commercial openers
Home openers are usually trolley-type units on a ceiling rail. Shops and warehouses often use heavier operators mounted at the side of the door. If your business door has an operator problem, see commercial garage door repair.
Opener acting up? Send us a photo of the unit and tell us what it does when you press the button. Call 613-265-3667 or request a quote. For the wider list of problems we fix, see garage door repair in Ottawa.
Garage door opener questions
Why does my garage door reverse before closing?
The sensors are the first suspect. Look for a blinking light on either sensor, wipe the lenses, and check that neither has been bumped. If the door reverses even with the sensors aligned, the close travel or force settings may be off, or the door is binding. We can sort that out.
My opener hums but the door doesn't move. What's wrong?
Usually a broken spring, a stripped gear, or a trolley that has come loose from the door. Turn the opener off and don't force the door. We'll find out which it is.
Should I repair or replace my garage door opener?
Repair suits a single failed part on a decent unit. Replace it if the opener is very old, the board or motor has failed, or you want better safety features or quieter operation. We'll give you both prices.
Why does my remote only work when I'm close to the garage?
A weak battery is the common cause, especially in cold weather. If a new battery doesn't help, the remote or the receiver may need replacing.
Can I use my opener during a power outage?
Not electrically, unless it has battery backup. You can use the manual release, but only when the door is fully closed, and expect it to be heavy.
Will a new opener work with my old door?
Usually, if the door is balanced and in good shape. A door with a bad spring or bent tracks needs those fixed first, or the new opener will fail the same way the old one did.
If the opener runs but the door will not move, closes and reverses, or only works while you hold the button, our guide to why a garage door won't open or close walks through the common causes and the checks that are safe to do first.
