Which Dominator opener do you have?
The Door Hero is not connected with Dominator. The steps here come from Dominator's own manuals.
Dominator, a B&D Doors (NZ) Ltd brand, has manuals for its sectional and tilt door openers (DSO-1V3 Select, DSO-2V3 Secure, DSO-3V3 Smart, DSO-4V3 Smart Pro) and its RDO-1V4 Excel roller door opener.
The model is on the rear of the opener; each holds up to 64 remotes. The Smart range, below, means the Smart Pro, Smart and Secure, which share a manual.
How to program a Dominator garage door remote at the opener
Smart range (DSO-4V3, DSO-3V3, DSO-2V3)
Power on, controls cover off, then press MODE until the remote LED lights. Hold the opener button for the function you want and the remote button together for 3 seconds, until the opener flashes and beeps. Let go, refit the cover and test.
Select (DSO-1V3)
Its manual uses the same presses as the Smart range.
Excel (RDO-1V4)
Power on, cover off. Press and release code set, then hold the remote button for 3 seconds and let go, twice. Test it.
Programming a Dominator remote from one that already works
Smart range
Within range, press a button on the working remote, then hold the button in its coding hole with a pen for 2 seconds, until the opener flashes and beeps. Hold the new remote's button for 3 seconds, release and repeat.
Excel (RDO-1V4)
Same pattern: 2 seconds in the working remote's coding hole, then 3 seconds on the new one, twice.
Select (DSO-1V3)
Check the manual for your model.
When a Dominator remote won't code or won't work
If a Smart range opener answers with 4, then OFF plus 4, its memory is full. The Excel won't take codes on battery backup, with its service light on, or while showing a blocked beam stopped it closing.
If no remote works a Smart range opener, its manual says to turn off vacation mode; the remote status LED flashes during that lockout. One dead remote may just need a fresh CR2032 cell: see garage remotes and button batteries.
How to reset a Dominator garage door opener
Erase every remote. Smart range: cover off, MODE until the remote LED is lit, then hold for 10 seconds until the flashing and beeping stop. Excel: hold the code set button for 6 seconds, until the LED flashes rapidly. Select: check the manual for your model. Then recode the remotes you keep.
Clear the limits. Smart range: MODE to the gear LED, then hold for 10 seconds. Excel: hold the button for 6 seconds, until the LED flashes quickly. Start setting the limits within 30 seconds, or the opener goes back to its original settings.
Memory reset. Factory defaults, keeping the remotes, history log and cycle counters; clear the limits first. Excel: power off, hold the button, power on, release when every LED is off. Smart range: check the manual for your model.
Dominator garage door troubleshooting
After the door runs, the Smart range's main light blinks off a number of times, then pauses. The Select (DSO-1) uses the same list, where 1 is normal. The Excel has its own lights.
Flash counts on the Smart range
| What Dominator's quick guide says | |
|---|---|
| 2 | A safety beam is stopping the door: clear it. If the beam seems faulty, hold a pre-coded remote button until the door closes. |
| 3 | Wireless Auto-Lock battery low |
| 4 | Wireless safety beam battery low |
| 5 | Wireless Auto-Lock still locked, stopping the door |
| 6 | Maintenance due: arrange a service |
| 7 | Standby battery faulty |
| 8 | The door was obstructed |
| 9 | Motor overloaded or stalled: arrange a door service |
| 10 | Running on battery backup: check the power supply |
Excel faults and auto-close
If the Excel's yellow service LED flashes and beeps, count the beeps and press LIMIT SET once; its manual says to contact Dominator if the fault keeps tripping. A door that stops or crawls may have flat backup batteries, which can take 24 to 48 hours to charge.
Dominator calls safety beams compulsory for auto-close on the Smart range and the Excel.
Springs, cables and a failed safety test
Dominator's manual says doors, springs, brackets and hardware are under extreme tension and can cause serious injury: never attempt an adjustment. If the door fails a safety test, use manual mode, move the door by hand only and call for service.
What to tell the door specialist
- The model, from the back of the opener
- What the lights are doing, and the flash count
- Anything since it last worked, such as a storm
- How hard the door is to move by hand
- Who installed it and when (usually on a sticker on the door)
What we would do
Count the flashes and note the model before resetting anything. Erasing remotes is easy to undo; clearing limits or the memory is not, and Dominator lists travel limits and force among its service checks. Not every door specialist works on every make, so say it's a Dominator when you tell us the job.
