We have a fridge that has been leaking from the freezer into the fridge. We recently took everything out of the freezer and turned it all the way down but now it looks like Alaska inside and it's frosted up and making loud noises. Is it worth saving or should we just cut our losses?

Any thoughts?
i have repaired a few fridges, dryers and washers with this site but nothing like this.
Please be constructive.

Thank you.
