Should you repair or replace your garage door opener?
Updated August 2026
← Every repair-or-replace call
Repair a garage door opener under 10 years old and replace one past 15, because a whole new opener installed is only $300–600. The common failures are small: a stripped drive gear kit at $60–150, a logic board at $100–250, a pair of photo-eye safety sensors at $30–90. Chain-drive units last 10–15 years, which is why a $250 board on a 14-year-old opener is more than half the price of a new unit that arrives with a warranty. That is where the arithmetic flips against repair.
The short version
An opener is cheap enough that the 50% rule bites early. Against a $400 replacement, any repair over roughly $200 deserves a hard look, and on a unit past 12 years the answer is usually the new opener. Under 10 years, fix it without hesitating: gears, sprockets, capacitors, remotes, and sensors are all inexpensive, and the motor itself rarely dies first. Past 15 there is a second argument that has nothing to do with money. Openers built before the mid-1990s use fixed codes that can be captured and replayed, and the oldest ones predate the photo-eye reversing sensors required on units made after 1993. A current model adds rolling-code security, a battery backup that still lifts the door in an outage, and phone control so you can confirm you did not leave it open.
Your situation, decided
| Situation | Verdict | Why |
|---|---|---|
| Under 10 years, drive gear stripped | Repair | A $60–150 gear kit restores a motor with years left |
| Logic board failed on an opener past 12 years | Replace | A $100–250 board is over half a $300–600 new unit |
| Door reverses for no reason, sensors misaligned | Repair | Often free: realign the photo eyes and wipe the lenses |
| Unit predates 1993 with no reversing sensors | Replace | It lacks the auto-reverse safety modern openers include |
| Motor runs but the door stays put | Repair | A stripped gear or a released trolley, not a dead opener |
| Past 15 years and you want backup power | Replace | A $300–600 unit adds a battery and rolling-code security |
What each path costs
Repairs typically run $60–250; a replacement is $300–600 installed. Chain and belt drive openers last 10–15 years. Repair under 10; past 15, a $300–600 replacement beats a $250 board and brings rolling codes and battery backup with it. Price your own number on the home maintenance cost calculator before you commit either way.
The repair-or-replace call is easy when you know the unit's age and service history. OnOtto keeps both, plus the maintenance that delays this decision for years.

The opener runs but the door does not move. Is the opener dead?
Almost never. Two cheap causes cover most of these. The emergency release cord may have been pulled, which disconnects the trolley from the door, and re-engaging it takes a minute. Or the plastic drive gear inside the motor head has stripped, which sounds like grinding and costs $60–150 in parts. Our walkthrough on an opener that runs without moving the door covers both. Check the release cord before anyone quotes you a replacement unit.
Is a belt drive worth the extra money over a chain drive?
If there is living space over or beside the garage, yes. A belt-drive opener costs roughly $75–150 more and runs noticeably quieter, since a rubber belt has no metal-on-metal contact. Both formats last about 10–15 years, so you are buying quiet, not longevity. On a detached garage the noise is irrelevant and a chain drive is the cheaper, tougher pick. Direct-drive models are quieter still and move a single part, but they cost more again.
Do I need a whole new opener to get a battery backup?
Generally yes. The battery lives inside the opener head, and only a handful of models accept an add-on pack, so retrofitting is rarely practical. That one feature is why plenty of people replace a working 12-year-old unit: a $300–600 opener with backup power still gets the car out during an outage, and California has required backup batteries on new residential openers since 2019. Phone control and rolling codes normally come in the same box.
How do I check that the safety sensors still work?
Set a cardboard box or a roll of paper towels in the path of the door and press the button. The door must reverse before it touches the object. Then test the second system by closing the door onto a flat 2x4 laid on the floor, where it should reverse on contact. If either test fails, realign the photo eyes until both indicator lights hold steady and wipe the lenses. Run both checks every month, and retire an opener that cannot pass.
