Please could you tell me which samsung fridge?

Please could you tell me which samsung fridge freezer you are referring to (regarding questions about fridge (freezer) not cooling after becoming noisy) as our fridge has recently stopped refridgerating after making loud noises (days after the warranty ran out!). We have a fridge freezer with twin cooling and built in ice maker and water dispenser. However, the water dispenser has stopped working. It isn't the water tube as water is still being provided to the ice tray in the freezer compartment - any ideas please???
