Hello Howard,Thanks ever so much for taking the trouble to reply to the question of my fridge problem,I would think that after reading your theory is that it is the refrigerant that needs topping up as it does't get cold enough despite the frost build up,and if I turn the thermostat down it does cut out,and starts up again when the stat is turned up but just keeps running to try to get to the set temp.
Thanks a lot,
John
