Garage door opener repair

Most calls that start with “the opener is broken” turn out to be something else — a spring, a sensor, or a remote. Working out which saves you paying for a part you did not need.

Opener not responding? Call and describe exactly what happens when you press the button. That usually narrows it down before anyone comes out.

What the symptom usually points to

Motor hums but the door does not move

Tell-tale: sound but no movement

The motor is receiving power and trying to run. On a chain or belt drive this often means a stripped drive gear inside the opener head, or a sheared trolley carriage. It can also mean the door itself is jammed or the springs have failed and the opener cannot lift the weight.

Check first: is the door heavy and unbalanced? If so, the opener is not the fault — the springs are, and that is a different repair.

Remote does not work but the wall button does

Tell-tale: one control works, the other does not

The opener and the door are both fine. This is a battery, a lost pairing, or a failing radio receiver. Try a fresh battery first, then re-pair using the learn button on the opener head.

If several remotes and the keypad all stopped at once, the receiver board is the more likely cause.

Nothing at all — no light, no sound

Tell-tale: completely dead

Check the outlet with something else, then the breaker, then whether the opener has been unplugged. If power is confirmed and the unit is still dead, it is usually the logic board or the transformer.

Door reverses on the way down

Tell-tale: starts to close, goes back up

Almost always the safety sensors or the close-limit setting rather than the opener itself. This has its own page — see garage door won’t close.

Keypad on the outside stopped working

Tell-tale: remotes and wall button work, keypad doesn’t

Usually a flat keypad battery or a keypad that has lost its programming — outdoor keypads take the weather. If the remotes stopped at the same time, look at the wall control first: some have a lock setting that blocks remotes and keypads.

Opener light flashing and the door won’t close

Tell-tale: the lights blink, the door goes back up

On many openers a flashing light means the safety sensors can’t see each other. Clear anything in the beam near the floor and wipe both lenses. If it carries on, see garage door won’t close.

App or Wi-Fi control stopped working

Tell-tale: the app shows the opener offline, the wall button still works

Usually the opener has lost its connection to the home network — a new router, a changed Wi-Fi password or a weak signal in the garage. The opener itself is often fine.

Door won’t open during a power cut

Tell-tale: no power to the house or the garage

Without power an opener can’t move the door unless it has battery backup. The manual release lets the door be lifted by hand, but only if the springs are intact — a door with a broken spring is very heavy. See garage door won’t open.

Drive types and what tends to fail

Chain drive

Most common, noisiest, generally the longest-lived

A chain pulls the trolley along the rail. Failures are usually the drive gear inside the head, a stretched chain needing tension adjustment, or the trolley carriage itself. Chain drives tolerate heavy doors well.

Belt drive

Quieter, common where a bedroom sits above the garage

A reinforced belt replaces the chain. The same gear and trolley failures apply, plus belt wear over a long service life. Quieter operation is the reason most people choose them.

Screw and direct drive

Fewer moving parts, more sensitive to lubrication

A threaded rod or a motor travelling along a fixed chain. Screw drives need the correct lubricant on the rod; the wrong product or none at all causes binding and premature wear.

Why the door matters more than the opener

An opener is sized to move a balanced door, not to lift a heavy one. If the springs have weakened, the opener takes up the difference, and it wears out early doing work it was never designed for.

This is why a technician checks door balance by hand with the opener disconnected before condemning the unit. A properly balanced door should be liftable with moderate effort and should stay roughly where it is left. If it slams down or shoots up, the springs are the problem and a new opener will fail the same way.

Repair or replace?

Openers are generally worth repairing when the fault is a gear set, a sensor, a remote or a limit switch, and the unit is otherwise sound. Replacement makes more sense when the logic board has failed on an older unit, when parts are no longer made, or when the opener predates the 1993 entrapment-protection requirement and has no photo-eye sensors fitted.

A technician will tell you which applies and why. You approve the price before any work is done.

Common questions

My opener hums but the door will not move. Is the opener broken?

Not necessarily. A humming motor means power is reaching it. That can be a stripped drive gear inside the opener, but it is just as often a broken spring making the door too heavy to lift. If the door is hard to move by hand, the springs are the likely cause.

Why did all my remotes stop working at once?

If every remote and the keypad stopped together, the receiver in the opener head is the more likely cause than several batteries failing simultaneously. If only one remote stopped, start with its battery.

How long should a garage door opener last?

It depends far more on how many cycles it runs and whether the door has been kept in balance than on age alone. An opener moving a well-balanced door does the work it was designed for; one fighting a heavy or binding door is doing work it was not, and wears out correspondingly sooner.

Can an old opener be made to work with modern safety sensors?

Sometimes, depending on the model and whether compatible sensors are still available. Openers manufactured before 1 January 1993 were built before entrapment protection was required, and retrofitting is not always possible. A technician will confirm what the unit supports.

Why is my garage door opener light blinking?

On many openers a blinking light is the opener reporting a problem, most often that the safety sensors are blocked or out of line. Clear the beam, clean the lenses and check the sensor brackets. If the light keeps blinking, call and describe the pattern.

Do you install new garage door openers?

Yes. If an opener isn’t worth repairing, we can install a new one. You’ll hear which makes more sense, and you approve the price before any work starts.
