Fridge freezer RF22R7351SR/EU fan issue

[Renmei]

Hi

We have the American style fridge freezer model number above. The fan started making a noise as if it was banging on something. I think the fan has now stopped working as the fridge is struggling to hold temperature. I think it’s ice build up. Will a defrost solve the issue or do I need it looked at?  Also I’m not sure on the standard warranty as it’s 2-3 years old 

many thanks.

Try a full defrost of the system and see does the noise go away. It could be ice build up. If not.. Call your local service place and see can they arrive with a fan anyway to replace it
