Nuevo 2007 Control Panel

LouLouQ wrote:the following control panel and battery

Hi and welcome to the forum - it looks like you intended to attach more info but it didn't work? There are several control panels that might have been fitted to a Nuevo of that age, so a photo of it will definitely help!.

One of the things that you may not have realised though: the 3-way fridges that A/S fit as standard cannot run from the battery if you are not on hookup. The 12 volt part is only for use while the engine is running (it takes too much power to be able to operate from the battery, which it would flatten quite quickly). So if you're away from mains hookup, you need to run the fridge on gas.

Welcome to the Forum.
Please forgive me if much of the following is known.

The general way in which the habitation electrics work is like this. When hooked up to mains, the mains comes via the trip switches to various places. One is the charger which tops up the leisure battery, which in turn powers the 12v devices such as lights.
Another mains feed goes to the fridge, so it can use its mains element. Another goes to the hob. Another feed the mains socket outlets.

Which lights are working? If they are the strip lights or similar fitted lights inside the van, they work from the leisure battery. So they don't help us. 

Assuming you're on hook-up, first check that something can work from the mains (e.g. by plugging a charger or a mains reading light etc) into a mains socket. If that doesn't work, then the problem lies at that level. The cable and its connector may be faulty, or the main"fuse" - the trip switch RCB - may have cut the current because of a fault.

But if a mains device does work, then the problem with the fridge not working on mains electricity may be because its element has died - or its RCB has tripped.

Turning specifically to the fridge, it can run on gas; it can run on mains; and (only when driving) it can keep itself cool via 12v.

The control panel should have an option to show the battery voltage. If the Hook up is operating through the charger the voltage should show >12.7v.

Is the charger switched on?
Have you checked the MCBs are on? If there is a normal 3 pin socket, plug something in it, does it work? ie is power coming through the hook up lead.

That's ridiculous - it's pretty much impossible to "blow" a fridge. The dealer should be named and shamed.

There are some very simple things you can do to check how far into your system the mains power is getting when on mains hookup. The simplest is to connect the hookup cable, then go to the mains circuit breakers, turn all of them on (switches all up, all little windows showing red) and then press the "Test" button on the main (biggest) circuit breaker. If the main circuit breaker trips off, you have mains to that point. If not, the problem is with the mains hookup itself (either the cable, the plug or the socket - or the way that you are using the socket).
