We went away to Scotland last week wildcamping and for the first few days the fridge was working fine on gas. Then we moved on and the fridge started to defrost - still on gas. It is an Dometic autoselect fridge/freezer. Can anyone tell me why? Is it because we weren't as level as we should have been, or did we cover the element in the fridge, or is there a switch we switched off by mistake, or is there something loose or is it non of the above? As soon as we got home, we plugged back in to 240v and it is now working fine. Help would be really appreciated before we take it into the dealer for them to sort it out.
