Tired of getting in and out of the car just to open and close the roller door on the garage, especially on rainy days?
There is an inexpensive solution if you are prepared to DIY install an electronic roller door opener.
Chamberlain roller door openers cost just a few hundred dollars from the hardware store and can be installed by one or two people in as little as two hours using just a few standard tools.
Each door opener kit comes with an instruction manual, which should be read thoroughly before proceeding with the installation.
Adding a weight bar
If the garage roller door has a base handle, remove it and attach the weight bar using the handle holes. Or, if there is no handle, centre the weight bar to mark and drill two 5.5mm holes. Position the bar on the roller door and secure with the supplied bolts, washers and nuts.
You’ll also need to check the measurements of the garage door, as the maximum allowable height is 4.5 metres, with a maximum door area of 16 square metres.
The door must also be spring balanced and the axle diameter no more than 35mm. Check all requirements carefully before purchasing an automatic door opener.

Install a rolling garage door opener
Check the door to ensure it is well balanced, and not sticking or binding, by disabling all locks. Lift the door
to halfway and move it up and down a few times. The door should remain spring balanced. If it doesn’t hold or binds anywhere, call a qualified door technician to make adjustments.
Install the stop collar on the shaft of the roller mechanism on the end opposite to where the door opener will be attached. Fit the stop collar hard against the boss of the door drum, tighten with a socket and check that the U-bolt holding the door shaft to the bracket is secure and tight.
Take the rope through the release handle and manual release cable. Open the door fully and tie it up, supporting the weight on a ladder. Remove the U-bolt and wall bracket. Slide the opener over the door shaft, engaging the drive legs in the drum wheel, and clamp. Refit the U-bolt and bracket.
Untie the door, then raise and lower by hand to check the operation in manual mode. Plug in the opener and turn it on, then use the buttons
to program it for right- or left-hand operation, open and close limits, and force settings. Cycle the door up and down so the force is set and learned.
Position a 40mm thick timber offcut flat on the floor and lower the door. If the door stops on the offcut, reprogram the limit settings and repeat the test. When the door reverses off the timber offcut, remove it and run the door opener through a full cycle.
