When the fridge is switched off what is the recommendation for either keeping the fridge door closed or slightly ajar (my Camperking had a setting on the door to keep it slightly ajar when not in use to prevent mould building up)?
It’s certainly advisable to keep the door open slightly when not in use to prevent mould and nasty smells.
Our caravan had a door clip designed for this.
In the MP we use a small folded towel to prop the door open slightly. It seems to work.
