Dometic 8505 fridge not working on gas...

First outing of the year and the fridge won't work on gas. If we set it to gas or it changes to gas on automatic, straight away the red light and the exclamation mark light start flashing, with intermittent bleeping as well (more exciting than TV really, but I digress).

We don't hear the igniter at all trying to light the gas - could this be the problem and if so is it easily fixable (Mr S not confident...).

Fingers crossed you can help :)

Ours does this when it’s waiting for gas to come through, we press the exclamation mark and restart the process until it lights. It doesn’t click any more once the exclamation mark lights up, sometimes we have to do it five or six times.
We normally go through this as part of our setting off procedure.

Not unusual after being laid up for a while. Try lighting the gas ring first to drag some gas through and know that you have gas. Try several times before deciding it will not light. If all else fails, remove the lower outside vent panel and light it with a taper or clean off (gently) any cobwebs that may have appeared.

There's definitely gas as we've been using the hob for a few days. Can't easily remove the outside vent panel as it is all siliconed in and the dealer is likely to have an attack of the vapours if we remove it!

This happened to us on our trip to Spain this year. Pressing the reset button resulted in a couple of clicks and then nothing. I was able to take the grill and the small metal cover on the right hand side off and could hear the click and see the spark but no flame. Took the van to a Dometic engineer in Spain who used compressed air to clear any debris in the burner and pipes - still no joy. He diagnosed that we needed a new gas valve (van is only 7 months old!!) but didn't have the part. When we got back from our trip I rang at least 5 Dometic approved engineers to try to get someone to have a look at it - all said they were booked up solid for the next 2 months. Van is currently booked in with UK dealer in May to have this fitted. Good luck with yours.

Has the van been serviced and the gas to the fridge turned off by any chance, the fact that you say "straight away" the red light comes on suggests that it's more than needing the burner cleaning, something faulting on start procedure but what is the big question, could be a stuck gas valve?

Ours does the trying to light clicking thing a few times before the red light comes on. We just press the red button and try try try again. Sometimes it works first time.
I think it depends on whether gas is in the pipe or it has to wait for it to come through.

I am never certain about anything but whether the dealer, an agent for Dometic or you sort out the gas problem, almost certainly the bottom outside vent may have to come off. I am puzzled when you say it is glued in place, for almost all work on the fridge can involve that panel coming off. It is usually held in place by 2 screws which require a quarter quarter turn to release, before gently releasing the cover. Unless your unit is different of course. I am concerned that the light goes red straight away; usually it goes to yellow for a while then red if it fails to ignite.

The vent covers on ours are secured by a sliding retainer on the left side of vent. A small lug protrudes and needs to be pushed up, probably use a small screwdriver as a drift to move it, that's how Dometic do it. The vent is then praised gently out on left side and a sharp tug should remove it completely. Can't help feeling if vent is fitted with silicon it's either broken or some other problem.

Thanks for all your help and replies, really appreciate this community.

We've been sidetracked by family for a few days, hence the delay in responding but we will have another look at trying to get the cover off from your advice @joka250 and @rosalan - but think the problem may be more serious as suggested as the igniting isn't sparking at all, just goes straight to red light.

Thanks again everyone and will let you know how we get on

You CLEVER CLEVER people! Thanks to you we managed to get the external vent cover off. Then before we tried anything too complicated we tried holding in the red exclamation mark button for a few seconds and Hey Presto we heard that glorious clicking sound of the igniter and all the lights went blue.

Have left it on and will check in half an hour but really think you have cracked it. I feel like turning into that lovely bosomy lady at the end of the Morecambe and Wise show (I think) who came on blowing kisses to everyone and saying "I love you all".... But luckily for you I won't.
