Garage Door Opener Repair in the Capital Region
Before anything else, do this test. Pull the emergency release cord and lift the door by hand. If the door is heavy, binds, or will not stay put halfway, your problem is the door and its springs, not the opener. An opener that is fighting a badly balanced door will fail, and replacing it without fixing the balance just breaks the new one.
Most opener problems are one of three things: photo-eye safety sensors out of alignment, a stripped drive gear, or limit and force settings that have drifted. Sensor faults are often free to fix yourself. Gear repairs run $180 to $380.
If the door moves smoothly by hand, then the fault genuinely is in the opener, and it is usually a small number of well-understood things.
Openers are also the one part of this trade where a fair amount is genuinely fixable by the homeowner, so this page tells you what to try before calling us.
Symptoms and what they usually mean
- Motor runs but the door does not move: stripped drive gear or a disconnected trolley
- Door will not close and the light flashes: photo-eye safety sensors, the most common fault of all
- Door reverses just before or just after touching the floor: close limit or force setting
- Door reverses partway up: force setting, or the door is binding
- Remotes work intermittently or only up close: dying battery, or radio interference from an LED bulb
- Wall button works but no remote does: receiver or programming
- Grinding noise with no movement: plastic drive gear has stripped
- Nothing at all, no lights: power, GFCI outlet, or a tripped breaker
Opener repair costs
| Fault | Typical cost | Notes |
|---|---|---|
| Sensor alignment | $120 to $180 | Often fixable yourself for free |
| Sensor replacement | $120 to $250 | Pair, including labour |
| Limit and force adjustment | $120 to $180 | Often part of another call |
| Drive gear kit | $180 to $320 | Worth it on a good opener |
| Belt or chain replacement | $180 to $380 | |
| Trolley or carriage repair | $150 to $300 | |
| Logic board replacement | $220 to $420 | Often uneconomic on an old unit |
| New remote or keypad | $60 to $160 | Programmed on site |
| New opener installed | $450 to $950 | See opener installation |
The safety sensors are not optional
Every residential garage door opener manufactured for sale in the United States since 1993 is required to have an external entrapment protection system, which in practice means the pair of photo-eyes mounted near the floor on each side of the opening. If the beam is broken while the door is closing, the door must reverse. That requirement exists because of a history of children being trapped under closing doors, and it is the reason your door refuses to close when a sensor is out of line. We will not disable, bypass or jumper them, and you should not let anyone else do it either. If your sensors are faulty, they get repaired or replaced. If an opener is old enough that it has no sensors at all, it predates the requirement and it should be replaced.
Repair or replace the opener
A gear kit on an opener that is otherwise sound and less than about twelve years old is good value, typically $180 to $320 against $450 to $950 for a new unit. Past that point the calculation shifts, and there are two reasons beyond age. The first is security: openers made before roughly 1996 use a fixed code rather than a rolling code, which means the signal can be captured and replayed. If your remote has DIP switches inside it, you have a fixed code opener and it is a genuine security weakness. The second is noise. If the opener is a chain drive on a bedroom-adjacent garage, a modern belt drive is dramatically quieter and that alone is often the reason people replace rather than repair.

How the project runs
- 1
Disconnect and test the door
Always first. An opener problem and a door balance problem look identical from the outside and the fix is completely different.
- 2
Check the simple things
Power, sensors, remote batteries and the emergency release trolley account for a large share of calls.
- 3
Diagnose the drive
Chain, belt and screw drives fail differently. A stripped gear is usually audible immediately.
- 4
Repair or advise replacement
A gear kit on a good opener is worth doing. On a twenty year old unit with no rolling code security, replacement is usually the better spend.
- 5
Reset limits and force
Both are adjusted and tested after any drive repair.
- 6
Safety test
Auto-reverse tested against an obstruction, sensors aligned and verified.
Try these before calling us
- Check both photo-eye sensors near the floor have solid, not flashing, indicator lights
- Wipe the sensor lenses. Cobwebs and road grit are a genuinely common cause
- Check nothing is sitting in the beam, including a bin, a bike wheel or a coiled hose
- Make sure a sensor has not been knocked out of alignment by a car door or a snow shovel
- Replace the remote battery, which is the single most common remote fault
- Swap an LED bulb in the opener for an incandescent or an LED rated for garage door openers, because some LEDs emit radio interference that kills remote range
- Check the GFCI outlet the opener is plugged into, and the breaker
- Confirm the emergency release trolley is re-engaged, since a pulled cord leaves the motor running with nothing attached

Frequently asked questions
Why will my garage door not close and the light keeps flashing?
The photo-eye safety sensors near the floor. Either they are misaligned, the lenses are dirty, something is in the beam, or one has failed. Check both indicator lights are solid rather than flashing, wipe the lenses, and clear the path. This is the most common opener fault and it is frequently free to fix.
My opener runs but the door does not move. What is wrong?
Usually either the plastic drive gear has stripped, which you can normally hear as grinding, or the emergency release trolley has been pulled and never re-engaged. Check the release first, since re-engaging it costs nothing. A stripped gear kit runs $180 to $320.
My remote stopped working. Is the opener broken?
Try the battery first, which is the most common cause by far. If the wall button works and remotes do not, it is the remote or the receiver. One underrated cause is LED bulbs: some emit radio interference that dramatically cuts remote range, so swapping the opener bulb for one rated for garage door openers sometimes fixes it outright.
How long does a garage door opener last?
Typically ten to fifteen years. The drive gear and the logic board are usually what fail first. If the opener is over twelve years old and needs a significant repair, replacement is often the better spend, particularly if it is a fixed code unit with DIP switch remotes.
Can you bypass the safety sensors?
No, and nobody reputable will. External entrapment protection has been federally required on residential openers since 1993 because of children being trapped under closing doors. If the sensors are faulty they get repaired or replaced. An opener with no sensors at all predates the requirement and should be replaced.
Should I fix my opener or replace it?
Repair if it is under about twelve years old and otherwise sound, since a gear kit at $180 to $320 beats $450 to $950 for a new unit. Replace if it is older, if it uses a fixed code rather than a rolling code, or if it is a chain drive next to a bedroom and the noise bothers you.
