    Hi all
    We had a problem last August with our Dometic RM7651L fridge freezer not working on gas .
    Resolved this by removing the fridge and turning it upside down
    This is the link to that problem
    https://www.motorhomefun.co.uk/forum/threads/help-fridge-not-working.155956/page-2

    After doing that the fridge worked fine.
    On all three power sources

    However the fridge now isn't working on mains electric
    Works fine on gas
    and fine on 12v

    The power selector switch led glows green when switched to mains.
    Any ideas as to the problem
    Many thanks guys
    Kev

    Probably the mains element has failed. It's a relatively cheap and easy fix.

    Yep, sounds like the mains element has gone.

    Check to see if there is 240v at the terminal block connection.

    If there is, and after isolating the mains, disconnect the element and check its resistance - should be about 250 ohms.

    I agree with the above, had it happen to me. Ours tripped the electrics when it went, first day of three weeks in France!

    As above easy to check, depending on access getting the failed element out can be a test but if you have already had the fridge out once doing it again will be easy if that is easier.

    I replaced the element in ours through the external vent spaces. No need to take the fridge out if you have top and bottom vents.

    The tricky part was getting the metal sheathing that covers the insulation clipped back on.

    Exactly my point, it was possible in my case but borderline, with experience of removal you can slide it forward and provide easier access to the shroud etc

    Mayne the 240v bits are still the wrong way up after being tipped upside down.
    Will it run off an inverter?:D

    No just as @bigtwin said it is the sheath or cowl removal and reinstatement. The element slides into a tube attached to the flue which is surrounded by rockwool which is held in place by the sheath which clips together, so to release it you have to sort of scrunch it together with your hands and as it goes a way up the back of the fridge there can be a shortage of space to get your arms in. Hence if you relieve the fridge fixings and slide it forward a bit it gives you more space to work, but try without first. The odd plug on the end of the cable can be a bit of a pain to pull off but it does come off.

    Don't worry, prior to selling the motorhome, I have a 12v element to change on our Thetford N150 fridge/freezer tomorrow.
    I feel your pain!

    Thats a very useful picture you can see the mains and 12vdc element wires half way up the sheath too.
