The motor runs, the door stays where it is

If the motor clearly runs — you can hear it working — but the door does not move at all, the opener has almost certainly become disconnected from the door rather than broken.

This is worth ten minutes of your own time. It is one of the most common paid call-outs in the trade, and one of the most commonly unnecessary.

The emergency release is the usual culprit

Every automatic opener has a red cord hanging from the rail. Pulling it disconnects the trolley from the door so the door can be operated by hand during a power cut.

Once pulled, the motor runs the trolley up and down the rail with nothing attached. Everything sounds exactly right and nothing happens.

To re-engage on most units: pull the red cord back toward the door (or, on some models, toward the motor) until the trolley lever clicks into its running position, then run the opener through one full cycle. The trolley will travel until it snaps back onto the carriage.

If the trolley is engaged and it still does nothing

Look at the drive itself. On a chain drive, a chain that has jumped its sprocket or gone visibly slack will slip under load. On a belt drive, check the belt is intact and tensioned.

A grinding noise with no movement on an older chain-drive unit usually means the plastic drive gear has stripped. That is a genuine repair, though often a cheaper one than a whole opener.

Common questions


How much should this cost if I do need someone?
Angi puts opener repair in New York City at $100–$300 as of 2026. If the unit needs replacing entirely, Angi's New York figure is $281–$630 installed, averaging $453.
Is it worth repairing an old opener?
Depends what failed and how old it is. A stripped drive gear on an otherwise sound unit is usually worth fixing. A logic board failure on a unit old enough to lack rolling-code security or modern safety sensors is usually the moment to replace it.

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.
