Frosty freezer

[MikeUniformMike]

The freezer seems to be full of snow. I defrosted it yesterday and it looks a bit frosty already.
Is there something I can do about it or is it time for a new freezer?

I don't know the answer but the freezer part of my fridge freezer does this, so bumping for you.

Thanks. There's ice on the outside top of it too.

Is it to do with the temp? Is it set too low? I've not long defrosted ours and it's starting to go again too quickly, so watching to see if anyone has any other ideas!
