We have a Whirlpool Gold

Question

We have a Whirlpool Gold side-by-side refrigerator. The freezer must have started defrosting today. Everything inside is soaked, the ice maker quit producing ice and the ice was melting. The blower fan is running continuously but not blowing any cold air. We did have the freezer packed pretty full but not much more than usual. It seems like the refrigerator is now starting to warm up. We have turned off the freezer side to see if it makes any difference. What else should we do?
