So I'm staying in a rented house for a couple months and the Zanussi fridge is making a loud noise.

I noticed that if I turn off where it says "Cool Air" the noise stops.

The owners didn't mention anything about the noise but they said they had it defrosted a few days ago because it had some ice and they just turned it on yesterday.

I noticed there's Ice inside the fridge so I guess the problem is that there's ICE on the "Cool Air" fan.

My question is if for now I can just turn off that "Cool air" fan?

Thanks
