Hello Suestore,

Welcome to the forum,

With a question like yours, it reads as though something has deteriorated through use or time.

Forum members don't have the opportunity to check your equipment in person, so all we can sometimes do is offer general tips.

With gas appliances, apart from normal wiping clean, there is not much you can do without having to start dismantle parts, and that should only be done by some one who is competent.

If you are not competent, then you probably need to call on the services of a professional.

We had a similar problem. Gas rings and oven/grill would start OK but then gas would stop coming out as the demand increased. The bulkhead regulator had failed. Got a new one fitted and it was sorted. Not a diy job unless you are suitably qualified.

Hi welcome to the forum
I find it strange all rings not staying lit are the other gas appliances working OK? water heater and heating when run on gas

There is not nearly enough information on the problem to be able to offer any advice except to get a qualified caravan engineer to look at it.
Because of the terminology used by the OP, I think that they know nothing of any value about gas and how the items actually work and what can or cannot be done and should seek professional help.

Welcome Sue Store.
I echo the Prof’s advice. Gas is dangerous so please be warned.

Facts. You say none of the three burners will stay alight?
Is there gas in your gas bottle?
Before you ignite the rings can you hear/smell gas coming through?
When the ring ignited how long do you hold the gas tap depressed?
Gaining access to the thermocouples is not an easy job. Other gas appliances , oven etc , may need to be removed.
You can remove the tops of each burner , two small screws. Lots of rust collects so cleaning out with a vacuum cleaner may help. Otherwise get a qualified mobile caravan engineer to sort it for you. Sadly people do die in caravans from Carbon Monoxide .

hi it stays lit if i keep my finger on button

 

[Dustydog]

It is possible the feed wire to the thermocouple unit has become disconnected. But to get to it involves gas work. Get an expert.

hi it stays lit if i keep my finger on button

Of course it stays lit when you keep the button pressed as you are overriding the safety cut off !!!!!!!!!!!!!!!!!
Get an engineer to sort it out !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Replace the regulator on the gas bottle as a first, and cheapest option, then take it from there. Each burner has its own thermocouple and it would be odd for all to fail at the same time!

For 'expert' read you need a caravan service tech who is GAS SAFE certified. These days not just anyone can work with gas, fixed or mobile.
