Sorry if I have posted this before.
I'm having issues with my Dometic three way fridge in our Jayco caravan. It works great on 240V & 12V when travelling. Yet on gas it doesn't work. There is gas coming through, the indicator on the front of the fridge shows that the gas is lit and working (in the green zone) and there is a flame at the burner. See photo.
I have cleaned the jet, gas is working ok as the hot plates work and they are next to the fridge. The fridge just doesn't stay cold. I have had other vans and the same fridge worked great on gas.
Any help would be appreciated.
Cheers,
Trebmal74

Hi Trebmal,
Your photo shows the flame not facing at right angles to the fridge flue. I have struck this problem with a Jayco before the burner not aligned at right angles with the flue and not getting the full benefit of the flame. The last one I worked on only required this to be done and worked like a charm.
The flame looks ok to me, hope this helps.

Was actually wondering if the flame look big enough or not.
Hard to tell from the photo, but if the thermostat has corroded it could be stuck on the pilot flame.

You could test this by watching the flame while someone turns the thermostat up & down from zero.

Was checking mine on the weekend & even at minimum temp setting the pilot flame still stays alight.

Cheers.

Hi Trembal,
I reckon TTD1 is on the mark. I had the same issue with my fridge but not all the time - which had me completely confused for a while. Generally, we use the gas more than electricity. The fridge worked great on gas but this one time we camped up for a few days, I noticed everything in the freezer was starting to thaw. Fortunately we were heading home after the weekend camping trip, so I gave the burner a good clean, thinking that it would have had some grit in it that was restricting the flame. Afterwards, I turned it back on while it was level inside my the shed and noted that after a few days the fridge was working fine on the gas. The same thing happened some months after on another weekend camping trip. It suddenly clicked that both times I hadn't been able to get the front of the van down enough for it to be level. I confirmed this by messing around to get the van level. It wasn't out of whack by very much, but it was enough to make a difference. Usually I can set the van up reasonably un-level most other ways (sideways, etc), but I can't have the front of the van up too much. I put this down to the burner not being correctly lined up under the boiler. I now overcome this by getting the front of the van dead level. I'm not saying that this is exactly what your problem is, but it could be that your burner may need to be adjusted to be correctly aligned under the boiler. Given that the fridge operates on the electrical element ok, this is where I would start. I hope my experience helps you. Cheeky1
