Questions for Garage Door Openers

Trouble Shooting
Before you start: Your garage door is probably the largest moving appliance in your home and your opener is an electric motor. It is therefore important to be aware of safety before you begin troubleshooting your opener.

– Make sure that the garage door is on the tracks, that the spring is not broken, that the tracks are firmly attached to the opening and that the door is mechanically stable. If any of these appear to be an issue call a service technician.

– Do not remove the cover from the operator or attempt to rectify any perceived electrical faults unless you are qualified to do so.

– Make sure there are no children or animals around blocking the garage door opening or in a position where they could block the opening.

– Note that all garage doors which can run smoothly on their tracks can be opened and closed manually by disengaging the manual release mechanism which usually entails pulling a leave or cord attached to the tracks on a sectional door opener and hanging off the engagement mechanism on the operator on the side of a roller door. For non finger safe doors special care needs to be taken when opening or closing doors to ensure fingers do not get caught between panels. Once the motor has been repaired or reset the disengagement mechanism needs to be re-engaged for the operator to function.

Step 1: Check the power

– Most garage door openers do not have battery backup so if the power is down or the circuit breaker for that circuit has tripped then your garage door opener will not work.

– If the circuit breaker has tripped then reset it and if it trips again after you have reset it immediately or when you try to open the garage door then your opener is faulty and needs to be repaired or replaced. If this is the case call a service technician.

• Step 2: If you have power but nothing happens when you push the remote button.

– If you have another remote handset then try the other remote handset or alternately for a roller door and some sectional doors you can use the wall button or buttons on the opener itself to open the door. If you are unable to open the door with another the wall button or directly then call a service technician.

– If neither handset opens the garage door then try to re -code the handsets to the operator.

– If only one of the remote handsets does not work then try replacing batteries and if this does not work then purchase a replacement remote handset.

• Step 3: If you have power and you can hear the motor running but the door does not open.

– If you have photo eye safety sensors then make sure the photo eye safety sensors are aligned and that the wires to the photo eye sensors have not been damaged. If out of alignment align the safety sensors.

– Check to see if no one has put the door into manual mode following a power failure. If the manual release lever is disengaged then re-engage.

– If the motor runs and the fault is not the manual engagement mechanism or photo eye then call a service technician.

• Step 4: If the door does not fully open or does not fully close when activated.

-Check to ensure that there are no physical objects interfering with the door operation.

​- If the door has electronic limits then it should reset automatically even after a power failure and there is something else wrong with the door and a service technician should be called.

– If the opener is an older model with manual limits then read the instruction manual to see how to reset limits or call a service technician.

AGDA Guide to Visual Inspection of Garage Doors
This Guide is not a legal document and is not intended to replace the relevant provisions of the Building Code of Australia or Australian Standards. The Guide is intended to provide the

reader with an understanding of the tolerances that a building professional will consider in determining whether a building element has been installed / constructed to an acceptable standard. The Guide should be regarded as an advisory resource rather than a series of prescriptive definitions.


Generally, variations in the surface colour, texture and finish of garage doors manufactured from pre- painted metals, painted metals, painted or stained timber or composite material, and variations in glass and similar transparent materials are to be viewed where possible from a normal viewing position. A normal viewing position is looking at the surface to be inspected at a distance of 2m or greater in normal daylight and “non-critical light” conditions. (“Non- critical light” is where light that strikes the surface is diffused, is not glancing or parallel to that surface).
Slight variations in the colour and finish of materials do not generally constitute a defect.


During pressing and bending processes the painted surface of a garage door is stretched and thinned. This sometimes results in micro-fracturing of the surface.
An acceptable level of micro fracturing is where the problem, or the results of the problem, cannot be seen in good daylight from a normal viewing position.


Differences of appearance or defects of a pre- painted metal surface are acceptable, if not clearly discernible from a normal viewing position. Minor scratches or other irregularities in paintwork will not affect the performance of the door and will not be deemed a defect. Normal environmental conditions over time can affect the pigment colouration in a pre-painted surface and, in particular, differences in formulation of any touch up paint used may present a different colouration to that of the whole surface and will not be deemed a defect.


Appendix C of AS/NZS 2311 – 2000, says, amongst other things, that the finish is considered acceptable if differences of appearance are not clearly discernible from a normal viewing position.


Rolling door curtains are wound into a spiral configuration where the individual layers in the spiral are in close proximity to each other. Manufacturers should avoid the layers coming into contact with each other where this results in rubbing of the paint surface.
An acceptable level of paint rubbing is where the problem, or the result of the problem, cannot be seen in good daylight from a normal viewing position.


Oil-Canning is defined as variation in the surface of pre-painted or painted metal, which appears as a series of undulations or distortions.

During pressing and bending processes the metal surface of a garage door is stretched and thinned. This sometimes results in oil-canning of the surface.
An acceptable level of oil-canning is where the distortion over any 150mm distance is not greater than 1mm. This should be measured using a 1mm thick feeler gauge between the surface of the door and a 150mm long straight edge.


Scratched, fractured, chipped or blemished glazing that is visible from a normal viewing position may constitute a defect.
Minor scratches, fractures, chips or blemishes within 5mm of the glazing edge will not be deemed a defect. Minor is less than 10mm in length and not more than 3 per panel.
