    a point has been raised on another thread, raised a query with me

    are fridge vent covers purely a convenience to keep down draughts?

    if not when should they be fitted?

    is it purely a temperature thing? if so when should they be taken back off again?

    hope they are not too critical, not sure where mine are :D

    They are supposed to be fitted in low temperatures (only bottom one needed). We found that our Fridge /Freezer worked better with them off in low temperatures.
    Suggest a bit of trial and error and take it from there. Don't buy new ones, Make some and hold on with a couple of bungi cords.

    Dometic either say 8 or 10 degrees or below, can't remember. My fridge has been cooling fine all week without them and it has been sub zero every night

    Thanks Andy

    I had no idea they suggested fitting below 10C and based on MH's I have seen at well below that without them fitted, nor do many others, or perhaps they have lost theirs like I have

    Setting off for the highlands next week, will make more effort to find them before I go :)

    You can get corrugated plastic sheet cut to size for about £3.0. I got 4 for £5.00. ?

    Just wondered why they are not supplied with van as standard if they are required below a certain temperature. Apologies if they are but not here in France.

    I guess because a some folks don't go away in winter so don't need them .. or at least don't go away in freezing weather..

    I know the covers are supposed to prevent the fridge from over-cooling at low ambient temperatures, but we have never had covers and never noticed any excessive cooling during the winter. Having survived without covers for 8 years, I don't plan to buy a set any time soon.

    might be wrong here,

    but I've always thought it was because the fridge uses a heat source to drive the cooling cycle.. ..

    so, if the ambient is too cold, it stops working efficiently and the fridge interior can get warm..

    That is the popular belief but apparently (I have not experienced this myself) some fridges struggle to cool because the heating elements or flame do not produce enough heat for the absorption process to function efficiently.

    EDIT I see Jim was saying the same while I was typing :ROFLMAO:

    I stand corrected. I have just checked the instructions and all it says is that the covers 'protect the fridge from excessively cold air'. I had assumed that meant it might get too cold inside.

    You are not being corrected, it is just a train of thought.
    I believe Dave Newell once had a notice from Dometic about this with certain fridges.

    As I said I personally have never encountered that.

    I didn't take it at all personally - just acknowledging that I had learnt something new today.

    I also put mine on in the summer when washing the MH to make sure water does not get inside

    I think ScotJimLand is closest - I recall being told that too. They aren't NECESSARY but are supposed to help, although I suspect not all setups are that critical.

    They do help the drafts though - although if the fridge seals are fitted correctly that SHOULDN'T be necessary.

    Tried using ours once as temps were below freezing all that happened was the fridge defrosted so haven't used them since works fine temps have been very low at night on this trip without problems.
