OK still getting to grips with our new camper and we went out on our first wild camp in the stang this weekend and it was great. now can someone explan this odd thing known as a 3 way fridge to me please ?

1) she works fine on mains hookup.

2) gas ? eh how can a fridge run on gas and how wuld this work as i drive with my gas off ?

3) 12v appear not to work at all.

before i take it to bits to work all this out does anyone have any knowlage about these things.

cheers.
 
12v should only work when the engine is running.
Gas when you are parked up and have no EHU.
240v when on EHU.
 
I often drive off forgetting to turn the fridge onto 12 volt.
Regarding safety, I have the facility to have the Truma heating on gas and operating when on the move so don't see having the fridge on gas when on the move as a problem but I'm sure many will disagree.
 
The fridge will have 2 switches on the front a red one and a green one, the red one should light when you start the engine, this is the 12v switch.
The Green switch will light when you are on electric hook up.

The gas should have 2 dials one to turn the gas on which you need to press in and press the ignite button or on some models a switch which when you turn it on will flash and you will hear a clicking noise from the fridge, if your fridge has this switch the flashing will stop when the fridge is alight.

If you have a push button igniter and hold the gas dial in, you should also have a small viewing window in the bottom back of the fridge , you need to look through this and keep pressing the igniter and keep the gas dial pressed in until you see a blue flame then keep the gas dial pressed for about 20 seconds the blue flame stays alight.
I hope this helps.

when on gas the fridge has to be level to work properly so when driving it is not. That being said say you have a crash petrol and a lite gas appliance don't go well together what the hell are you thinking I don't care a f@@@@ about you but if I am behind you I care about me.
so please see sence and do as the fridge is made for 12 volt driving 240 on hook up and gas when no hook up .
They are desined this way for a reason
 
The controls depend on the make and model of fridge. There are many more possibilities than described above.

Some motorhome gas installations are fitted with a device to cut off the gas supply in the event that the pipe suffers a catastrophic fracture (e.g. in the event of an accident).

It makes sense to switch from gas to 12v while driving as you will economise on use of gas.
 
If you are heading through Peterborough, I will be happy to show you. Just PM me for details.

And what's your thoughts on lpg fuelled vehicles and motorhomes like mine that allow the Truma combi to be used on the move to heat the habitation area ?

I prefer to run the fridge on gas because it workes best IMHO. But I have a crash-save regulator which turns the gas supply off in case of impact.
From my experience it takes a considerable amount of time for the fridge to work properly again when switching sources. So I only use 12Volt if I am going to drive for a while. When sitting at home, I switch the fridge on with gas a few hours before (or even the night before) and keep it going on gas for shorter distances or when I know we don't use 240V at the destination.

I have used the fridge on gas even when parked with two wheels on the pavement. So it does work, even when not level.
 
Actually, it didn't fail once DUE TO negotiating hills, roundabouts, etc. The problem arises when it's level and stationary.

Ok you all think i am soft that's fine.
but if it was ok to use a gas appliance on the move whey do Electrolux make a 3 way fridge years ago I worked for a caravan company as a fitter and I would never have told a customer to use gas on the move perhaps I am old and things have changed.
But old habits dye hard and I think I will stick with my opinion :D
i will stick with my opinion and feel safe as for a truma being able to stay lite as you drive WHY you have heating from the engine don't you.
I get myself in the **** loads on here maybe it's my age lol
 
Not too sure how accurate that statement is, many a time I've pulled the fuel hose off of a carb and had petrol spill onto the extremely hot exhaust and all it did was vaporise. One major cause of fire in car accidents was with the brake fluid resevoir breaking free/rupturing and spilling it's contents over the exhaust manifold and bursting into flames, diesel would no doubt react in a simliar way.

Obviously any fluid that was released as a spray would ignite easily and petrol only needs a spark.

I have never used the hab heating to date as I tend to be on my own when out and about but I assume it's for when you have passengers onboard in the hab area which is a fair distance from the cab.
 
well I would think it's ignited by the sparks of the scraping over the tarmac metal. When a bike get's crashed, it's usually upside down or at least on it's side
and the tank is more often than not separated from the bike and not dripping down to the exhaust.
And racing bikes tanks are filled with fire retardent foam as well to combat going up in flames. It takes some serious sparks to light them up and it happens very rarely.

I am one of the braver ones I believe, but having the choice I would still turn the burning flame off when in the belly of ship out of my sight
 
We can have our opinions on this but I feel safe with mine next you will all be telling me you have the wife cooking on gas as you test your skills driving through the Alps at break neck speeds ;)
 
BTW running on lpg is totally different to a naked flame dur omg am I talking to children
