My appliance only works for approx. two weeks at a time - it gradually gets noisier and makes clicking sounds and then both fridge and freezer temperatures rise. If I turn off for a day or so, it works fine for another two weeks and then the fault occurs again. Do you have any idea what may be the cause, I have had service people look at it but no cure as yet?
