Dr Greg, When you say your running on " Yellow " propane / butane gas, is this a refillable cylinder, like Gaslow etc, as Calor use red and Blue cylinders, patio gas use green .
Where does the Yellow cylinder come from, come on Prof , you should have noticed this, mate.

There are many different suppliers of LPG, there is no requirement for them to follow a colour code for the bottles. Each supplier can have a different colour scheme to identify their own bottles. The only requirement is the printing on the bottle must identify its content.

The supplier of the gas is irrelevant. all Butane and Propane sold to the general public will compliant with the commercial standards. What is important is the correct pressure regulator that must be used.

If any suppliers cylinder is empty the Cascade should show green followed by red indicating it has failed to detect a flame.

Hi Prof
Thank you
It is a Butane cylinder. On the day in question it had shown the above : green + red, however since I had discovered the tap (regulator) been off, the green indicator stays on (no red) and the sparker will not spark, it just stays green with no action. I had attempted with and without the isolator switch with 5min interval several times, and it was still the same. I may get new (reffiled cylinder) of Butane today and try it again. It was working absolutely fine untill recent events. Stranger things.

Hi there.
He's stillat at, so the update is:
I had found out, that my Carver is the 1983 model that I believe has no electric part.
Mon. AM I had replaced the Butane cylinder for the new one, and guess what, still the same.
In the afternoon I got hold on my friends Carver Cascade Mk2 GE that he had replace (lucky him) for the new Whale heater. I had replaced the "igniting/flame" part, it does klick, desnt give a spark and after few sec. the red light comes on. I had managed to light the flames externally and it worked. Reseted a few times, still no ignition. There is an additional 4 pin inlet in the 1998 version and I wonder does it have something to do with ingition or the GE (submertion) part. Oh... Beauty of the good aulde caravan bringing to life. Reminds me of the "Bringing out of dead" classic.

The 1983 model was one of the first Cascade 2 models, and as you say it didn't have the mains electric element.

The additional 4 pins on the 1988 burner control module were just an alternative wiring arrangement to enable caravan manufactures could fit the switch control into their own control panels. It had nothing to do with the electric element which always had entirely separate wiring and control.

The symptom you are describing suggests that both your old burner control module and the later one are both faulty. You may be lucky and find a replacement on Ebay, or there are companies that do offer refurbishment.

I believe Arc Systems were offering such a service.

Incidentally there was company that made a copy of the Cascade called Henry. Most parts are interchangeable.

Hi John.
I wonder is it the ctrl panel inside the caravan, the one with the switch and 3 leds?
The 1998 burner was sparking well before it was taking away from friends caravan.
I may contac Henry (is it Henry in Arc?) to come up with fix or solution for the above. It is very annoying, having water heater without the hot water on the taps, especialky when camping away from the camp sites.
Thank you John.

The switch panel on the pre 1988 model would not cause the symptoms you have described. The green only shows that power is connected and turned on, The red is controlled from the Burner control module. The yellow does have some voltage sensing circuitry and if it illuminates it prevents the Burner control module from even opening the gas valve, As a result of you telling me the heater is stone cold, if the gas valve opens but there is no ignition spark it means the burner control module is faulty.
