The short version
Whether to repair or replace a garage door opener usually comes down to three things: how old it is, whether it has today's safety features, and whether parts are still available. A newer opener with one failed part is almost always worth repairing. An old one with no safety sensors, or one that's on its third repair, usually isn't. If you'd rather just have someone look, call me at (619) 930-7869. I'll tell you what's wrong and give you both options before you decide.
Before anything else, make sure it's really the opener. A lot of opener complaints are actually the door. If the springs are weak or the door is binding, the opener strains, makes noise and gives up, and a new opener won't fix that. I check the door's balance first on every opener call.
To check the balance, I pull the release and lift the door by hand. If your door feels very heavy or drops when you let go, the springs are the problem, not the opener. Don't run the opener on it, and don't try to adjust the springs.
The questions I ask
- How old is it?Many openers last somewhere around 10 to 15 years with normal use. Past that, other parts tend to follow the first one that failed.
- Does it have safety sensors?Openers made since 1993 have to reverse when something is in the way, and most use photo eyes near the floor. If yours has no sensors, it's old enough that I'd replace it for safety alone.
- Does it have battery backup?Since July 2019, California's SB 969 has required battery backup on residential openers sold or installed in the state. It lets you get the car out during a power outage.
- Can I still get parts?Gears, boards and sensors for common brands are easy to find for years. For discontinued or off-brand units, they can be hard to get or not worth it.
- Is this the first problem or the fifth?One failure on a solid opener is normal wear. A string of failures means the unit is wearing out as a whole.
- Does it do what you need?Noise over a bedroom, smartphone control, a heavy wood door that needs more power. Sometimes the old opener works fine but doesn't fit the house anymore.
Repairs that are usually worth it
Brand matters a little here. LiftMaster, Chamberlain and Craftsman openers share a lot of parts, and Genie has its own. If you know your brand, I have pages on LiftMaster opener repair and Genie opener repair that go through the common problems for each.
- 1Stripped drive gearThe motor hums but the door doesn't move. On many chain and belt openers it's a plastic gear inside that wears out, and replacing it brings a good opener back to life.
- 2Safety sensorsBlinking lights, a door that reverses for no reason. Realigning, rewiring or replacing a pair of sensors is a quick fix.
- 3Logic boardThe opener doesn't respond, or acts erratically after a power surge. A board can be worth replacing on a newer unit.
- 4Remotes and keypadsDead remotes, lost keypads, or new cars that need programming. Usually simple.
- 5Travel limits and forceThe door stops short or reverses at the floor. Often an adjustment, not a part.
When I recommend replacing it
No safety sensors. If the opener predates photo eyes, it doesn't reverse reliably for a person or a pet in the doorway. That's the one case where I'll push for a new one even if the old one runs.
It's old and the repair is a big one. If a unit is well into its second decade and needs a motor or a board, the repair money goes a long way toward a new opener with a warranty, battery backup and modern security.
Old remotes with fixed codes. Very old openers use codes that can be copied. Newer openers change the code every time you press the button.
It's loud and the garage is next to living space. A belt-drive or side-mount (jackshaft) opener can make a big difference in a garage under a bedroom.
When I install, it's usually a LiftMaster: chain drive, belt drive, or by special order a heavy-duty or side-mount unit. For garages too tight for a standard rail, it's Marantec. I set it up with the sensors, battery backup and remotes, adjust the limits and force for your door, and walk you through it before I leave. Parts come with a 1-year warranty and labor with 30 days, in writing.
Making the call
Here's the rule of thumb I use with customers. If the opener is fairly new, has sensors and battery backup, and this is its first real problem, repair it. If it's old, missing safety features, or the repair is a big share of what a new one would be, replace it. Anything in between, I'll lay out both options side by side and let you pick.
Whichever way you go, the door itself should be in good shape. A new opener on a door with tired springs or worn rollers will wear out early, and a repaired opener will keep failing if the door is binding. That's why I look at the whole system, not just the motor on the ceiling, and I'll tell you if the door needs attention first.
