Fridge Freezer poping sound

[robbiefurn]

I have an interegrated fridege freezer not sure of the model, its 3 years old. It makes a poping noise somtimes . Somtimes it quite loud other times is not so much. Only started doing this in the last few months. The sound is best described as a pop/dull clatter just a pop then its gone . Sounds like its from within, maybe the compressor kicking in...hard to say. Any thoughts would be greatly appreciated thank you
