Samsung Fridge Freezer - Freezer Warm

[Chrismawa]

Wondered if anyone would have any idea whats going on with my Fridge Freezer. The upper fridge part works and has worked fine since it was bought. However the bottom freezer compartment randomly goes off at times, resulting in losing the food that's stored in there. Its happened about 3 times now. I have turned the unit off for a period of time and then back on and this has fixed the issue temporarily. Any ideas or is it time to replace? Unit is around 4 years old.

Thanks.
