Re: ZANUSSI ZX56/4 fridge not cooling
I’ve had a similar problem with my frost free zanussi zbf249w model.
No cooling in fridge & red hot compressor
In my case in the rear of the freezer section were 4 screws. On removing these screws remove the plastic cover.
behind the cover is what i presume is the evaporator & a fan which is used to circulate cold air up into the fridge section & around the freezer.
My evaporator was heavily frozen so i switched off & defrosted it with an hair Dryer. The fan appeared to be running ok so I can’t understand why the air wasn’t flowing around the fridge section, unless it started running once the plastic cover was removed.
Mine has been ok for a few days but I suspect their maybe a reason for the unit not defrosting etc.
Worth a try as a possible short term fix…..Don’t use anything sharp when trying to defrost otherwise you’ll risk serious damage to the freezer.
