Fridge not working

The fridge on my 2003 auto sleeper executive has always worked ok, and it’s still ok when using a hook up, but it’s not working when driving along and the red light isn’t coming on. Has anyone got any idea what’s wrong?

Fuse blown. Unfortunately  these fuses can be in a couple of places, first they may be close to leisure battery (possibly under drivers seat). You should find two fuses together, one is for split charge system the other for the 12v supply to fridge. Second, they may be above the engine battery in the engine bay, often just hanging close to the scuttle. In this case water runs off the scuttle onto the fuses corroding the fuse holders and either blowing the fuse or just stopping the fuse making a good connection.  The fuse holder may need replacing as well as the fuse.

Thanks for the quick reply, I thought it might be a fuse, but not sure where to look. I’ll see if I can get at it and sort it out. I’m away in Scotland, so at least it’s not boiling hot and the fridge stays cool from being plugged in.

Fixed it ! 
Thanks Paul

If it was a fuse, where was it, good to know for others?

The fuse was underneath the drivers seat, it hadn’t blown, but pulling it out and pushing it back in seemed to fix it. I think that must have reset the relay.

Be warned: damage to the wiring in this area is very common on A/S vans of that age. The problem is often high resistance at one end of the fuse (often a poorly made crimp which causes the wiring to overheat).

If it were mine I would examine it carefully. The problem gets worse because the heat makes the fuse holder terminals less springy so they grip less well, terminal resistance goes up and so it gets hotter. It's not unusual for the whole fuseholder to melt. So worth looking at carefully before that can happen.

I should add that this is not by any means certain to happen! I've owned 5 A/S conversions and it has happened on none of them. But it does happen on a few, and it's frustrating if it happens while you're away - not easy to fix without the right tools.

Thanks for that, it’s still working ok, but we’ll check it out properly when we get home in a few days.

I have had that problem in my last van not autosleeper  as you say the fuse holder melted  but did not blow fuse  .cured by fitting a much better quality  fuse holder
