Hi all.
Got back from our round Australia trip and had no fridge problems, but went off up the coast on new year and discovered that the fridge was not working on DC, so I have tested connection on car side, van side, and all fuses, all looks OK, but behind fridge I cant find power.
Any suggestions appreciated.
Cheers
Rob.

Often I have found that if the fridge/Caravan is not level the fridge does not work on AC or DC. Try on AC first then Gas.... then change over to DC. A = Arive at park D = Depart park.

Thanks Keith
It works well on AC and Gas, but when I put it on DC for traveling, it just does not work.
Cheers.

Somewhere in the back of the fridge there will be a 12v heating element, unless there is a fault in the wiring, that's a likely culprit.

Hi
Brand & model number of fridge could save a lot of wild guessing.!
But with most the 12V element rarely burns out
It is the 240V element that can have a short life with some models
If you can get to the back of the fridge you should be able to see the12V input terminals BUT TURN OFF & remove the 240V plug before poking around in there.

Thanks disco driver and oldtrack.
Its a Dometic 90 Lt.
Opening up at the back I can't see the heating element but there are 2 terminal connections one says ignition and the other says heating, and there is no power there. looks like I may need an electrician.

We had a similar problem and then our fridge fuse started to blow in hot weather. In absolute desperation we actually checked the fridge manual! It seemed the fuse was too small. We installed the correct fuse and no more problems on DC. Lynne and John

I thought that was standard for 3 ways on dc, they just never run properly.
Personally i wouldn't worry about it.

Hi Nutta.
You are correct, but this one just does not work at all.
Cheers

Hi
Most of them never run properly on 12v because most of them are never wired properly
.Most of them do not get 12V at their terminals WHEN running!!!

They all run pretty well when heavy enough wire is used. I am yet to see a caravan constructor install wiring the size required by Dometic.
Some of the later models have elements of the same rating as the 240 V element and include thermostats them over cooling the fridge.
