Fridge freezing

[Portland Billy]

My boat fridge has decided to become a freezer.
After being on for about an hour everything gets frozen, even with the setting on low.
Any ideas.
Perhaps a new fridge, but could live without the expense!!

Just sounds like a dodgy thermostat

If you turn the stat to off does it go off , if so turn on to see if it comes on . What make model is it . Anyone can change the stat .

Or the door doesn’t close as it should, letting the cold out and the warmer air in.
