How can i keep my  freezer from icing over.?

If it's not frost-free, you can't. I defrost mine every so often. I do wipe out the freezer part with a lot of rubbing alcohol after defrosting and drying it well. I can't really say if that helps?

when your fan switch is on do not open the fridge. so your freezer, not icing over.

you probably have a seal leak somewhere that lets air in which makes the freezer frost up more than usual.

Keep it full, then theres no room for the ice to develop.

If all else has failed see if its level.If not clean water tray underneath vaccum around fan and coils and try to shem it level.Otherwise its defrosting time.

It depends on how much your want to keep your freezer
