Odd problem with Dometic fridge gas operation

Hi, I've got a problem with the Dometic RMS8551 fridge (not AES) in my AutoTrail motorhome. Any and all suggestions would be appreciated.

Day 1: Walking past the van and the gas igniter was sparking athough the fridge was turned off at its front control panel. Got the keys and returned to the van and sparking had stopped. Turned the fridge on at the control panel but couldn't get it to operate on gas - not sparking or igniting when pressing the button for gas operation. Checked: i) fridge is operating (getting cold) on mains power and switching ok between mains and 12V when the engine is running ii) there is gas in the bottle iii) no errors to reset iv) no build-up of dirt in the igniter.

Day 2: Next day and magically everything was functioning OK - able to switch between mains and 12V and the gas was operating as normal, and lighting on the first click.

Day 3: Now back to where we were on Day 1 - operating fine on mains and 12V power but not operating on gas - no spark and no ignition. One difference this time was that after selecting gas the fridge showed an error after a few seconds. Cleared the error but it returned every time I tried to switch to gas.

Any suggestions about the source of the problem? The control panel appears to be functioning OK. The big mystery (and hopefully the biggest clue) is why would the gas igniter start clicking on its own?

I cannot offer any suggestions about the fridge trying to light the gas when switched off. However, what gas are you using? If you have butane then the inconsistent behaviour could be caused by variations in outside temperature as butane will not work when it is around freezing point..
