Garage Door Opener Repair & Replacement

Your Opener Doesn’t Lift the Door

This is the single most useful thing to know before you spend money, and almost nobody is told it: the springs lift the door. A correctly balanced door weighs almost nothing in your hands — the springs are wound to cancel it out. The opener only has to nudge that balanced weight along the track and hold it in place.

Which means an opener that strains, hums, or lifts a few inches and quits is very often a healthy opener reporting a spring problem. A quarter-horsepower motor is not going to move two hundred pounds of steel, and it was never asked to. Replacing that opener buys you a new machine that fails the same way.

The test takes thirty seconds. With the door fully closed, pull the red release cord and lift by hand. A balanced door comes up smoothly and stays roughly where you leave it. If it feels like lifting a car, the springs are the problem and the opener is fine. Broken spring repair →

The Faults We Actually See

Openers fail in a short list of ways, and most of the list is cheap:

• Stripped drive gear — the nylon gear that the motor turns wears out and rounds off. The motor runs, the trolley doesn’t move. A gear kit, and one of the cheaper repairs on the door.
• Failed capacitor — the motor buzzes, tries, and can’t get started. A part the size of a film canister.
• Logic board — no lights, no response from anything, while the outlet still works. Often a surge, which is why we see a run of them after a bad Houston storm.
• Safety sensors — misaligned, dirty, or with the wire pinched somewhere along the wall. The blinking light on the motor unit is the opener telling you exactly this.
• Travel and force limits — a door that stops short of the floor, or bounces back up as it lands. Settings, not parts, on most units.
• Remotes, keypads and wall controls — batteries, re-learning a remote to the unit, or a wall control whose wire has broken behind the drywall staple that’s been pinching it for years.

Repair or Replace

Usually repair. On a unit under roughly ten or twelve years old, gears, capacitors, sensors and controls are normal wear parts on a machine with plenty of life left, and they cost a fraction of a new opener fitted.

Replacement is the honest answer in four cases: the board is dead and discontinued, or costs most of a new unit; the opener has no photo eyes at all, which dates it to before 1993 and makes it a genuine hazard; it has been under water, where the board and the motor windings don’t come back; or the rail and trolley are as worn as the motor and you’d be fixing the same machine twice. We’ll tell you which of those you have while we’re standing under it.

Safety Eyes Are Not Optional

The two small sensors about six inches off the floor are the door’s entrapment protection. Openers made for the US market since 1993 have to have them — that came out of the federal safety rules, not a local ordinance — and an opener without any is old enough that its age is the problem.

They are also the most common false alarm on the whole door. Before you call anyone: wipe both lenses with a dry cloth, move whatever is parked in front of them, and check they’re still pointed at each other. Bikes, trash cans and boxes knock them out of line constantly. When that isn’t it, the fault is usually the wiring rather than the eyes themselves.

Battery Backup, and Why It Matters Here

Houston loses power. Without a backup, an outage means the release cord and lifting a heavy door by hand — awkward on a good day, and genuinely unsafe if the door is already partway up.

A backup battery runs the opener for a limited number of cycles with no mains power. It is not on every unit, and we’re not going to pretend it is. If you want it, say so before we fit anything and we’ll quote a model that has it. The Chamberlain in the photo below is one.

Brands and Model Numbers

The common residential ones: Chamberlain, LiftMaster, Genie, and the Craftsman openers Sears sold, which Chamberlain built. Plus the builder-grade units that come with new construction out around Katy.

If you want a straight answer on the phone, read us the model number off the label on the side of the motor housing. That one string tells us the gear, the board and whether the parts still exist — and it’s the difference between “we’ll take a look” and “we have it on the truck”.

What It Costs

The estimate is free and there is no service-call charge. A technician looks at the opener, tells you what failed and what it takes to fix it, and you decide with a firm number in front of you.

We don’t publish repair prices. A gear kit and a new opener fitted are different orders of magnitude, and quoting either one before anyone has seen the unit is a guess or a starting figure that climbs.

Parts carry a 5-year warranty and our workmanship is covered for 90 days.
