    It's averaging 35c here and the fridge isn't playing. Is this normal ?

    I've got it on 24 hours a day on 240 and still the beer is only lukewarm :(

    In the mornings (after a cooler night) the milk and fruit juice is quite chilled, but through the day it all warms up :(

    Is this just a failing for Dometic in such warm climes ?

    It's a bit cooler where we're heading = 28 day and 20 night.

    Any tips ? I've seen folk say to turn it upside down, but not sure if that comment was beer driven ;)

    its just what happens . morocco is a favourite even in winter for them playing up. most change to either a 12v compressor fridge or fit a household one through an inverter .
    even then older fridges seem to run on modified sine wave inverters but the new fridges require pure sine wave . /and a few solar panels and batteries . i run mine all winter in spain etc . and in summer run an extention lead into the house to run my house fridge and the freezer for nothing off the solar on my trailer . saves about 40p a week.

    were just back from Valence near the Alps and the temperatures were 36c and only dropped to 25c at night and on mains electric the freezer compartment struggled to keep the food frozen
    Switched it on to gas and it maintained -18c without any problems

    If you have the fridge set to max, try turning it down to medium. Fridge doesn't work so hard and doesn't generate so much heat so cools better.
    It was a tip from Jim (our esteemed leader) and it worked for us in Morocco.
    If that doesn't work, try cleaning the flue. If it's full of soot and crap that also reduces the cooling efficiency (again, learnt by experience in Morocco)
    Whatever you do, DO NOT use a pin the "clean out" the jet or let anybody else do it. It ruins the jet and the fridge is buggered until you can get a new jet.
    Im sure more techie types will be along shortly to give more techie advice.

    We have loads of solar and hardly ever use EHU. I forget that there are others who do things differently.
    Lesson learned, don't presume!

    A compressor fridge is the answer but you can fit fans to improve performance. @Techno100 is the expert.

    The 3 way fridges work best on gas and even better with some supplementary fans to cool them down a bit at the back

    you need more airflow over the fins at the back in warmer temperatures. a couple of 100mm computer fans do the job fine pulling air out of the top vent. easy diy to make up or buy the ready made kit for about £40. fitting takes about 20 minutes unless you have hands like JCB buckets like mine

    In the recent heatwave in France our fridge worked best on gas . We also tried to make sure that the fridge side of the van was in the shade if possible .

    Get thee sen a fan in the top vent extracting the warm air.

    Any fridge working in temps "averaging 35c" will struggle. Fitting a fan or fans to pull the warm air out of top vent will help. Have you tried removing top and bottom vents to allow more air flow around fins?

    Solution to warm beer -

    1. buy a bucket.
    2. Fill bucket with bought ice
    3. Insert beer in bucket
    4. Drink all beer before the water gets warm,

    Foolproof(y)

    Edit - repeat points 1-4 as needed.

    Is your van level
    A slope can affect the efficiency

    Yup. Nice and flat.


    And as per advice above, I've taken a panel off to allow more air circulation.

    Seems to be working :)

    As Abacist say run it on gas and fit a couple of fans in the top vent.
    Not only is the fridge more efficent on gas your mains supply on site is probably not much over 200v, even if you have 220v it will not work as well as on 240v in the UK.
