This is a snip from one of my posts about our roadtrip.
There was a fridge lock too, called Vent. Is vent known as locked in some other language? German? Gattina?
Gattina knows I think five languages and she did not know the word as locked in any language she knew.
Margaret was travelling in her and her husband's caravan at the same time as we were and so probably did not read the post and I expect she would have explained the word and what it meant had she have read the post.
I have just discovered it for myself, but I will see if Margaret knows the word and what it is about.
Over to you in comments, Margaret.
Later edit: I discovered that when you are not using your campervan or caravan for an extended period, you need to leave the door of the fridge ajar to prevent a build up of smells or mildew. You vent the fridge by pushing the lever across so that the fridge door stays open when it is switched off and unused. With some fridges it is a pop out thing within the side of the fridge door or a plastic bit that just sticks out. Makes sense.
