Ive got a GE Profile side by side fridge freezer and its not cooling enough, we recently moved and brought this along with us, unfortunately we forgot to renew our appliance insurance policy when we moved, I know Ive found the manual online before but Im damned if I can find it now, It worked when we first moved for about 3 weeks and since then has just got slowly worse. Is there anything I can do to remedy this myself, any help would be most appreciated. Its a damn good fridge freezer and I dont want the expense of replacing it (Ive seen Z's cheeper than a new one of these!!)
