Noticed my side by side unit not cooling in fridge and not freezing in freezer. Took back panel off in freezer and coils were completely encased in ice. Fan above coils is working. I defrosted the coils with hair dryer and turned unit back on. Will this fix the problem or do I need to replace parts? Has only been turned back on for about 30 minutes now, how long will it take to notice if it is cooling again? Thanks.

First off, this is the "Air Conditioner" repair section.
