My 18 month old AEG frost free fridge freezer has begun making horrible 'grinding and scraping' type noises from somewhere within the freezer unit. They seem to continue throughout the night mostly. I've no idea how the unit 'knows' it's night time, perhaps it's because the door isn't being opened much then.
A few months back (also just out of the warranty period) the whole thing overheated during a warm spell of weather and both temperature displays (+4 and -18 deg) went well above their set values. I noticed the single compressor unit was getting too hot to touch (about 50 deg C) and since then I've kept a fan blowing on it. If I remove this fan the compressor gets very hot and I'm worried the whole thing will fail again but maybe I'm actually causing some kind of problem and leading to all this noise. Can anyone help? Thanks.
