Summary: The frost free feature of this refrigerator never worked. Ice builds up in the freezer, then the air channel down to the refrigerator part gets blocked with ice and the refrigerator temperature goes up to 60. We have had numerous service calls by factory authorized repairmen, and numerous parts replaced, sometimes twice. Frigidaire customer service has been unhelpful and unresponsive, not answering calls and letters.
Summary: To answer all complaints on "knocking" sounds, this is normal , due to the new freon being injected into the systems. By dealing with these little inconveniences, you can sleep well at night knowing that its better for the environment. If you read your manual, it clearly states this. Also, how can we complain on value when the prices of appliances are the same price, if not cheaper than 10 yrs. ago???
