Dometic RM8400 proplems

[Clangers]

Just been away for a few days in a "new to us" Eldiss 175 Majestic and after 2 days on 240v. the fridge would not cool.
I have scrolled through the posts for fridge problems and it seems a cooling fan system will might help. The only thing is, people are saying it's for very hot situations and the last 3 days have been so cold we have had the heating on day and night. Is that the problem I wonder? the interior getting too hot as opposed to the outside temp too hot.
Any help or suggestions would be greatly appreciated.

probably the 240v heater element has failed

does it work on gas

We've got the same fridge. It won't need a fan in this weather, it even worked in Spain without a fan. Good fridge normally

Just a thought, I've a different fridge, an RM5310 in our Accordo (but probably similar as it's Elddis), but I remember reading it has a thermostat on hookup and gas (but not on 12v). Couldn't be that could it? Though if it's fine on gas probably not. And agree with R&A post above - it shouldn't need a fan in this weather! I think I'd take off the bottom external cover and see if the bottom of the chimney's hot (with care!). Oh and on mine there's a 6A mains fridge/charger current trip ... sorry - just trying to think of cheaper things to fix than the element!

When on 240v does the top vent feel warm, if not probably the 240v element that's failed.

Not got it turned right up have you? they normally work best on just below three quarters/twenty to eight position.

Yes the top vent feels warm

If the top vent is warm it would suggest the 240v element is working,next time out try it a lower setting.The other thing to have a look at is the state of the thermal transfer paste on the back of the fins inside the fridge to see if it needs replacing,or is it OK on gas?
