Re: fridge not getting cold enough.
my mate defrosted fridge overnight set the fridge on number 4 and checked the thermometer about 1pm it was just in the blue safe mark,he has just checked it again 3pm its gone back up into the red mark. is it the thermostat whats at fault.
one thing I forgot to mention was that the fridge freezer is a built in model ( kitchen cabinet)in a showmens caravan and only has one small air vent behind the fridge could the fridge be not getting enough air supply.
