For most Melbourne garages, the right opener is a quiet belt drive on a sectional door, or a drum-mounted motor on a roller door, sized to the door you actually have and fitted with working safety beams.
If you have not settled on the door yet, sort that out first. The door type decides which openers will even fit, and we cover that choice in our comparison of sectional, roller and tilt garage doors.
Which drive type suits your door?
Sectional and tilt doors usually take a ceiling-mounted opener with a rail running back from the door. The motor pulls a carriage along the rail, and what drives that carriage is the real choice.
- Chain drive: tough and usually the cheapest. It is also the noisiest, which matters if there is a bedroom over or beside the garage.
- Belt drive: same idea with a reinforced rubber belt. Much quieter, which suits an attached garage.
- Screw drive: a threaded rod turns to move the carriage. Fewer parts, but it does not love big swings in temperature, and a Melbourne garage can be freezing in July and baking in January.
- Wall mount (jackshaft): sits beside the door and turns the torsion bar directly. No rail across the ceiling, so it suits garages where you want that space for racks or a high vehicle.
Roller doors are their own thing. The opener mounts on the drum or axle the curtain winds onto, so there is no rail at all. You buy an opener made for roller doors, matched to the curtain size. A sectional opener will not do the job.
Is a bigger motor always better?
No. Match the opener to the door’s size and weight and to how often it runs. A double-width insulated sectional is a lot heavier than a single roller door. If the garage is the family’s front door and it cycles a dozen times a day, buy for that duty, not the bare minimum.
The opener is not a crane. The springs do the lifting. A properly balanced door should stay put about halfway up when you let go of it by hand, and lift without much effort. If it slams down or shoots up, the springs need adjusting. A bigger motor just hides the problem. Get the door balanced before any opener goes on.
What safety features should it have?
Any opener worth buying should have these:
- Obstruction sensing with auto-reverse: if the door meets resistance on the way down, it stops and goes back up.
- Photo-electric beams: a pair of sensors near the floor either side of the opening. Break the beam while the door is closing and it reverses. Essential if there are kids or pets around.
- Manual release: a cord or lever that disconnects the door from the motor, so you can open it by hand.
- Battery backup: keeps the opener working through a blackout for a limited number of cycles.
Know where your manual release is before you need it. In a power cut without battery backup, pull the release with the door fully closed if you can, then lift by hand. Pulling it on a half-open door with tired springs can bring the door down quickly, so keep clear of the path underneath.
Remotes, keypads and button batteries
A remote that runs on a small button or coin battery is a real hazard if there are young children in the house. Product Safety Australia advises checking that the battery compartment on any product is child resistant, storing spare and used batteries well out of reach, and acting immediately if you think a child has swallowed one. Their button battery safety page sets out what to do.
When you change a battery, check the cover still screws or clips shut properly. If it has gone loose, replace the remote.
A wall keypad outside is handy for kids coming home from school. Change the code from whatever the installer set, and change it again if a tradie or a former tenant has had it.
Power for the motor
The opener needs a power point in the ceiling near where the motor sits, not an extension lead strung across the garage. If there is not one there, a licensed electrician needs to install it. If you are planning a garage from scratch, have the outlet put in with everything else; our guide to garage power, lighting and EV charging covers that planning.
Servicing: what you can check and what you can’t
A quick monthly test takes a few minutes:
- Reversal test: lay a piece of timber flat on the floor in the door’s path and close the door. It should reverse when it touches the timber.
- Beam test: start the door closing, then wave a broom handle through the beam. The door should stop and go back up.
- Balance test: pull the manual release with the door closed, lift it halfway by hand and let go. It should roughly hold.
- Look and listen: check the rail, chain or belt for slack, and listen for new noises.
Call a technician if the door fails the reversal or beam test, runs slower than it used to, reverses for no reason, jerks or shudders, or makes grinding or banging noises.
Springs and cables are the one area to leave alone completely. They hold a lot of stored tension, and a spring or cable that lets go while someone is adjusting it can cause serious injury. Anything involving the springs, cables or drums is a job for a garage door technician.
