What you are seeing
Callers booking opener repair usually describe the fault by a sound it makes or a move the door refuses to make, and these are the common versions.
- The motor whirs and the light comes on, but the door sits there with the chain idle
- A hum from the motor head and then nothing, or one click per press of the button
- The door rises fine, then reverses a foot or so before it reaches the floor
- The wall button does nothing, or the door starts moving when nobody touched a control
- Grinding or popping from the rail as the trolley passes the same spot
- Dead silence after a storm outage, even though the outlet has power again
What we do on a door opener repair visit
We work from the door inward to the circuit board, because a door that fights its opener is behind a lot of the parts that break.
Release the opener and test the door alone
With the door fully closed, we pull the emergency release and raise the door ourselves. One that glides up and parks at halfway is sound, so the fault is inside the opener. One that feels heavy, hangs crooked or binds needs spring, cable or roller work first, or the repaired opener just strips its next gear. Safety note: we release only with the door down, because a broken spring can drop the door the moment the trolley lets go.
Listen, watch and read the codes
We run the door from the wall button and a remote while watching the motor head. Many newer units flash a diagnostic pattern on an LED or the light bulb. A motor that spins while the chain stands still points at the gear; a hum with no movement, at the capacitor or a binding door. A lone click points at the board, and a unit that answers the wall button but ignores the remote points at radio parts.
Open the motor head and swap the failed part
The opener gets unplugged before the cover comes off. A stripped drive gear often leaves shavings in the bottom of the housing. The new gear and sprocket go in with fresh grease, and travel gets rechecked so the door stops where it should. A failed board is replaced by model number, a weak capacitor by its rating, and every new part runs under load before the cover goes back on.
Go over the rail, trolley and drive
Everything between the motor and the door gets checked next: we look for a cracked trolley or a tired release spring, set chain tension so it stops slapping the rail, and check belts for frayed edges and missing teeth. A screw drive gets cleaned and regreased with the lubricant its maker calls for. Bracket and door arm bolts loosen after years of vibration, and a bowed top section means the reinforcement bracket needs work.
Set limits and force, then prove the reverse
The down limit is set so the bottom seal just compresses against the slab, and the up limit so the door clears the opening without banging the stops. Force goes to the lowest setting that moves the door cleanly. Then a two-by-four laid flat under the door confirms it reverses on contact, a hand through the photo-eye beam confirms the sensors, and remotes get reprogrammed if the board was replaced.
What the opener is telling you, sound by sound
Most opener faults can be narrowed down from the driveway by matching what you hear and see to the usual culprit.
| What you notice | Usual cause | What we do |
|---|---|---|
| Motor runs, chain or belt stands still | Stripped drive gear | New gear and sprocket, fresh grease, travel rechecked |
| A hum, then nothing | Tired start capacitor in an older AC motor, or a locked or binding door | Free the door, then test and replace the capacitor |
| One click, no motor | Relay or logic board fault | Test, then replace the board by model |
| Reverses just short of the floor | Down limit set too long, or a spring weakening | Check balance, then reset limit and force |
| Wall button dead, or the door runs by itself | Pinched or shorted wall wire, or a failed button | Trace and replace the wire or button |
| Grinding at one spot on the rail | Cracked trolley, slack chain or bent rail | Replace the trolley, set tension, fix the rail |
Why an icy morning can strip an opener gear
A bottom seal iced to the concrete pins the door while the opener keeps pulling, and the weakest link gives: often the drive gear, sometimes the door arm or the top section where its bracket bolts on.
Portland airport averages about 32 days a year when the low dips to freezing or below, and the freezing rain storms of February 2021 and January 2024 glazed driveways right up to the door. Rain that runs under the seal at night can lock it in place by morning.
If the door will not lift on a frosty morning, stop pressing the button. Pull the release with the door down, free the seal gently, and reconnect only once the door moves by hand.
Steep driveways and tuck-under garages need finer limits
A sloped slab meets the door unevenly, so the down limit has to be set finely: one that seals the high side can leave a gap on the low side, or make the opener sense resistance and reverse.
It shows up on hillside streets in Hillsdale and the Southwest Hills, where some garages sit under the house, around Prune Hill in Camas, and in West Linn. A heavy two-car door on a hillside house loads the opener harder, too.
We set the limit for the slab you have, often add a taller bottom seal for the low side, and run the reverse test at more than one point.
Is a new logic board worth the money?
On an opener with photo eyes, a healthy motor and boards still in production, usually yes; on an older unit with a discontinued board, or one where the gear failed at the same time, usually no.
Boards fail from surges, from moisture in a damp detached garage, or from age, and the sign is a click, a dead wall button or lights flashing while the motor never starts. A shorted wall wire can look identical from the driveway, so we confirm before ordering.
What changes the price
The posted opener repair price covers diagnosis and the common adjustments; a few findings add parts or time, and you hear about them before we start.
- A logic board, receiver board or motor, priced by model
- Discontinued parts that need a substitute or a special order
- A bent rail, cracked header bracket or torn top section from a forced door
- Rewiring a wall button or sensor run that was stapled through or chewed
- Wall-mount openers, which take model-specific parts
- Spring, cable or roller work the door needs first (its own line on the quote)
When a repair stops making sense
Repair stops making sense when the opener predates the 1993 federal entrapment rule and has no photo eyes, when the motor has burned out on an older chain unit, or when the board and the gear fail within weeks of each other.
It runs the other way too. A stripped gear on a ten-year-old opener with working photo eyes is routine, and replacing that unit would sell you something you do not need. When the call is close, you get both numbers before any work starts.
Door opener repair: common questions
Can you replace a stripped opener gear on the first visit?
Usually, yes. Gear and sprocket kits for the common LiftMaster, Chamberlain and Craftsman chain and belt units ride on the truck, and the swap takes about an hour. Less common brands may need a kit ordered by model number, so a photo of the sticker on the motor head helps before we come out.
Is a 15-year-old garage door opener worth repairing?
Often it is, provided the opener has photo eyes and a strong motor. Gears, trolleys, capacitors and many boards for openers of that age are often still available. The balance tips toward a new unit when the radio is an older fixed-code system, the unit is too weak for a heavier door, or two major parts fail together.
Should I turn up the force when my opener reverses near the floor?
No. Extra force makes the door push harder before it reverses, which defeats the feature that keeps it from crushing whatever is underneath. The usual causes are a down limit set too long, a bottom seal that froze or swelled, or a weakening spring. We find which one it is and set force back to the minimum.
Can a power outage or surge ruin a garage door opener?
An outage alone rarely does, but a surge when the power returns can take out a logic board. Check the breaker and the ceiling outlet first, then unplug the unit for a minute and plug it back in. If it still sits silent or only clicks, we test the board before ordering one.
Do you repair Genie screw-drive openers?
Yes. A Genie screw drive moves the door with a carriage riding a long threaded rod, so most repairs come down to a worn carriage or a dry, dirty screw. We clean the screw, regrease it with the lubricant Genie specifies, replace worn parts and reset travel. Genie belt and chain models get the same diagnosis as any brand.
