I have a Hotpoint Mistral Plus FF (model # 8596P), and – following advice from this forum – corrected a temperature problem by replacing the two thermistors.
However, since the repair the FF seems to be working / running nearly all the time, and so I wonder whether there is a further fault that needs to be corrected.
Sorry – I should have stated that it is the compressor that is running constantly (or at least 95{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the time )
on the front of the fridge is a large kick plate,remove this by gently prising off, and check to see if the pipework at the front right is blocked with hair etc , this is called the condensor and would make the compressor run for long periods if blocked
