Ok Fridge freezer- It can work down to -15degree's*. However every so often (last time was a year ago) it defrosts multiple times a week spoiling the food in the freezer.
Last time I realised we had too much food in the freezer compartment where the fan is located- sorted that and its been fine since.
Its started doing it again, Can it be that you can also overfill the rest of the freezer and air needs to circulate properly for it to work?
I've checked the black compressor(?) at the back- its warm not hot-hot.
Its currently working but making a quite low rumbling sound (best way to describe it).
I'm loathe to bin it. Our last fridge/freezer lasted 10yrs and I'm conscious that a repair man will cost a sizeable call out chunk etc.
Could turning it off- leaving it to stand for a couple of days and cleaning all the coils on the back help?
Ps. Theres enough air flow behind. However there was a window vent immediately to its left that I had sealed two weeks ago due to fruit flies getting in from the bins.
*The Fridge leaves indoors and under the stairs facing the kitchen.
