My freezer has an F4 error. We ordered the part from UK white goods and replaced it but the error has got worse. Please could anyone advise how to resolve it.
The 9590102 sensor is correct to replace either sensor in the fridge, however an F4 fault is the freezer evaporator sensor failure and on your unit ( KGNves 3846 ) on an Index 27A-147 you need sensor 9590214.
