Your garage door starts down, then goes back up
A door that starts down and then reverses is the single most common call in this trade, and it is also the one most likely to cost you nothing at all. Work through this before you pay anybody.
Federal law requires an automatic opener to reverse when something breaks the beam near the floor. So a reversing door is usually the safety system working correctly — for the wrong reason.
Check the photo-eyes first
There are two small sensors mounted a few inches off the floor on either side of the opening, facing each other. One sends an invisible beam, the other receives it.
Look at the indicator lights on both. On most units a steady light on each means alignment is good; a flickering, dim, or dark light on one means they have lost sight of each other. Wipe both lenses — cobwebs, road salt and a film of dust are all it takes — and check nothing is parked in the beam, including a bin, a bike wheel, or a coiled hose.
If one bracket has been knocked, loosen the wing nut, move the sensor until the light goes steady, and tighten it again. That fixes a large share of these.
Then check the travel limit
If the sensors are fine, the opener may be set to stop short. Most units have a screw or a pair of buttons marked for down travel; the manual for your model will say which way to turn it.
Adjust in small increments. Set too far and the door presses into the floor, the opener reads that resistance as an obstruction, and it reverses — the same symptom from the opposite cause.
When it is not the opener at all
If the door also feels heavy, hangs crooked, or grinds on the way down, stop. Those point at the spring, a cable, or the track — mechanical faults that a limit adjustment will only mask.
A door that is out of balance will keep tripping the opener's obstruction sensing no matter how the limits are set, and forcing it makes the underlying fault worse.
Common questions
- How much does a safety sensor repair cost?
- Often nothing, because realignment and a wipe of the lenses fixes it. Where a sensor genuinely needs replacing, Angi puts opener repair in New York City at $100–$300 as of 2026.
- Can I just disconnect the sensors?
- No. They are a federally required safety device on automatic openers, and they are what stops a door closing on a child or a pet. Bypassing them is both unlawful to do on a residential installation and the reason the requirement exists.

Your quote can come in below these ranges, and it can come in above them. Both happen for legitimate reasons: a simple reset costs less than a full replacement, and difficult access, a heavy or non-standard door, seized hardware, or damage found once the door is open all cost more. These are published by the sources named, not by us, and nobody can price your door from a web page. Use them to start a conversation, not to end one.
