model number ZRB934FX2
The fridge freezer is operating OK frost on the back
Have you misunderstood, the noise is at the back of the fridge section, not the freezer
There is no frost in the freezer section, and the whirling sound has just stopped. if the problem is as you describe an ice problem, does it mean that i need to turn off for a short time to clear it?
the noise is definitely from the fridge high up at the back. I could stop it immediately by opening the door, but as soon as I close it , it returns.
