i did find one site that said they had stock but just to check a faulty stat will give a few symptoms
over freezing in which case it almost 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} the stat
no life at all in which case it may be the stat or a failed compessor
some cold but not enough can only be the stat if the compressor switches on and off. if it keeps running its a system fault
