Is it an auto select or manual, it needs a12 volt supply to work on mains gas and 12volt. The 12 volt from when the engine is running is a separate supply to the control circuit depending on how old your fridge is. A model number and year would help get more info

if you have nothing at all and all was working previously then you need to find the main fuse that supplies the fridge.
likely to be near your charging unit.

I don't know your fridge but most have a fuse at the pcb.

not working on anything and no lights you need to find out if you have 12vs to the control side if you remove the lower vent from outside you should be able to see a connector block marked +- and d+ you need to check you have 12v across the plus and minus

Just so you know what is going on - the fridge works by applying a small amount of heat to the cooling circuit. This heat circulates the coolant and causes cooling. The heat can be from a 240V mains element, a 12V element or a small gas flame. There is a control board that controls the automatic and manual selection of the heat source.
The control board is powered by 12V, usually from the leisure battery via the 12V fuse box. This is a low-power circuit. If this control board isn't powered, nothing works.
The 12V power for the 12V heater element is usually totally separate, and comes from the starter battery/alternator, not the leisure battery. It is relatively high power (about 200 watts) so the wires are usually thicker.
The control board is usually located near the switches, at the top of the fridge. But the power inputs and heater elements are usually located at the back of the fridge, at the bottom. As mitzimad says, usually you can remove the lower cooling vent on the outside, for access to the power connections.
The first thing to check is that the 12V supply to the control board is OK. Have you used these fridges before? They are silent in operation, and take quite a long time to get noticeably cool. Are you sure it's not working?

no lights so i would assume a fault

Is it just the fridge that's not working, or are there other 12V circuits also not working? Presumably there's a 12V power distribution fusebox - what make and model is it? Do you have a multimeter for checking voltages?

- since 1997 (many years tugger before then)
Similar fault happened on our RM 7 series quite recently...no lights / power at the control board...all fuses checked ok...12v checked and present at the back of the unit, after taking off the bottom vent. Then contacted Leisuretech at Clitheroe, they're working mobile and came to my house a few days later...fault diagnosed and repaired within 20 mins...broken corroded 12v feed wire that only became apparent after tugging it, also replaced the temp selector dial which had a broken shaft (didn't think that felt right from getting the van).
Clitheroe is about 15 miles from me...cost £80...very reasonable.
They did say it was their second same fault repair that week.
hope that helps

I had a lot of trouble with my domestic fridge when I bought my new Delaware
domestic sent a rep to my home to look at it when the dealer could not fix it
he said it needed a new fridge ;;;
ok fine at least it gets the problem solved . should not have happened in a brand new van but that’s life :::::
but wait for it
it turns out that after waiting 4 weeks domestic don’t make that fridge any more aaaaaaa you have got to be joking says I
they did not advise me I had to find out my self though customer service
The end answer I had to accept a repair because the replacement model Was shorter and did not fit
I insisted the domestic engineer was present when the part was replaced
which happened
when I collected the van I was told that I was low on gas
which I refilled on my way home but there’s plenty of gas in the tanks
i was not told that the fridge worked on electric and battery but not gas
it was not till I left for Spain last year that I found out that the fridge did not work on gas
lucky for me when we arrived at the rally in Spain a friend could see what the problem was .
The liquid that’s in the pipes had leaked over the gas pilot which stop it working
when I returned to the UK in. a rush as we all did I spoke to the domestic rep Who apologised But
one thing he did advise was to leave the fridge on low when parked at
what he said makes sense if you think about .
our fridges at home are on all the time we dont switch them off and on
while I’ve been parked at home I’ve left it on low
but who knows
but there you go
happy days

Are you saying that a Domestic (Dometic) rep told you to leave the fridge on low 24/7/365, ie NEVER switch it off ?

The bit in posting #24 says this (I've split it into two parts for clarity);
I returned to the UK in. a rush as we all did I spoke to the domestic rep Who apologised But

Which certainly sounded to me like the fridge in the MH to be on 24/7/365. I've never heard of that before ! Imagine the usage of electricity, or worse gas, to have the fridge running constantly for no reason.
Greta would be outraged !

Hello and welcome to MotorhomeFun,
Starting with some basics, you seem to have gone very quiet, so I assume you’ve used up all of your 5 free posts, pay the £15 it could well help you sort your fridge+ problem, as it will cost you at least 5 times that if you have to take it to a caravan workshop, many members on here have sorted many a problem through this forum. Right then you say it was working on 240V only at first but not now, have you plugged anything else into one of your 240V sockets to check you have 240V power, and to confirm that you haven’t tripped the power in the van, if that’s all fine, then you’ll need to check each and every habitation fuse related to the fridge even for it to work on 12V/240V/ or gas, also make sure you have got gas and it’s turned on, next are all other 12V points working e.g. can you hear the pump running are the 12V lights working in the habitation side, if not, it sounds like a heavy main 12V fuse, there are usually 2 fuses adjacent to the VEHICLE battery one supplies current to the fridge when engine is running, the other supplies current to your leisure battery/s, it would help when you have checked out the above, also you should find another 12volt distribution panel with a number of fuses for the 12volt side, check them all, you could have some damp got into your 12v, if the van has been stood without periodic checking throughout the winter, if you could post exactly what make and model of Motorhome you have I’m sure there must be at least a few members on here with the identical model, which would help narrow things down a little, another point, where did you buy it from was it a Motorhome dealer or privately, whichever you could go back to them and explain and they could probably point you in the right direction as to where all your fuses and relays are located, all the above wil be far more beneficial both financially and knowledgeable than putting it in the hands of a workshop, think of £55an hour plus parts and vat, and you could be looking at a few hours work, a lot of which you could carry out yourself or have you got a local friend who is or neighbour who is a Motorhomer, I’m sue either would be willing to help you. Hope this helps you, Let us all know how you get on.

I have never heard of anyone being advised to leave a fridge on permanently, at least not when parked up and not in use, sounds like the weirdest advice I’ve ever heard, I’ve certainly not done it in 46years of caravanning/Motorhome ownership, the cost of calor or electricity would be outrageous and totally unnecessary, I have fingers crossed, never had a problem with Dometic fridges in 14 caravans and 8motorhomes, except when I had a THETFORD fridge which was a nightmare and it seems a few have had problems with Thetford fridges, my van has had to stand like everyone else’s since October but I am fairly confident that when I try and light it in the next few days that it will fire up almost straight away, fingers crossed.
