Hi folks, I have a door works RD2 auto garage door opener https://doorworks.com.au/doorworks-rd2/

 

Tonight it opened twice by itself! I've hastily disconnected the power..

 

Just wondering of any tips to follow for troubleshooting what might be occurring?

 

A remote issue? Another user with same code (it says 1.2m codes..)? Some physical fault?

 

Thanks

This line in the PDF sums it up:

 

Transmitter:Frequency - 433mHz Coding Type – fixed code

 

You been cloned by someone screwing around probably.

 

IMO if you cant disable the inbuilt fixed code reciever from being active and the garage door controls access to the house as well, then you should rip that opener out and throw it away.

Watch this which will show how easy these fixed code ones are to trigger.

Sometimes it can be simpler than a 3rd party with the same code or some sort of universal opener. We had some phantom openings that turned out to be poorly designed remotes. The buttons were easily operated when the remote was in a coat pocket or purse. I glued a guard over the buttons so it needs a deliberate finger press.

I have the same problem with a new car's keyless entry remotes. The buttons are too easily bumped when in pocket or purse. This could be quite common. The car only unlocks for a short period then if the doors aren't opened it locks again.

Although cloning could be done it's not really likely to be the problem in the real world. Our door started doing exactly the same thing a few months ago. We got a guy round to service the door and he said that the PCB in the motor unit could be failing - and if that was true, in our case, we would need a whole new motor drive unit (the manuf is no longer supporting our model - which brings a whole new kettle of CGA fish because it's only four years old).

 

Anyway - he reset the up and down stop limits (and also did other lube servicing etc). All for $142 incl GST (Auckland area) and it's been fine since.

This was my first thought as well - remote control with dodgy switches. They usually have little micro switches and when they get a bit old the springs break down and they can be very touchy.
