Question

I have an LG Fridge freezer model ref GR642QVP. The digital temperature display at the front keeps beeping randomly, and the actual temperature goes up and down constantly whilst beeping taking place - ie from 3 to 0 back up to 2 then down again etc. intermittently occuring problem, but occuring more frequently of late. many thanks. 07725 035510 ms barker.
