Why buy a new one without first knowing the fault. If it is something serious & expensive then ok time for a new fridge. It may however be something as simple as a thermostat or sensor which is faulty & stopping compressor from running. Get someone to check it.

So your going to pay someone money, to come out and tell you that you need a new fridge freezer, just go out and buy a new one. There, I've just saved you some money, please donate what I've saved you, to a charity of your choice.
