My name is ***** ***** I will assist you with your appliance today.
I am sorry to hear you are having trouble with your appliance.
I understand how frustrating that can be.
If the door seal is fine then this indicates temperature issue and/or an air flow problem due to heavy ice build-up inside the rear wall of the appliance.
The noise may be coming from fan hitting ice inside the rear or the fan motor itself is faulty.
Please try this:
Leave it unplugged and empty with door open for around 24-36 hours.
Then plug it back (expect some water on the floor) and wait for another 8 hours so it gets back to optimum temperature.
The problem should be resolved.
However, if the issue appears again then the problem is with the fan motor that will need replacement.
Please do not hesitate to ask any follow up questions.
I hope you enjoyed your experience with justanswer.co.uk today.
Have a wonderful day.
