My Whirlpool model WRF736SDAM14 freezer stopped cooling, Then we noticed the top refrigerator stopped cooling. We moved all food out, and it sat over night. I know it got over 50 degrees in the refrigerator area. The next morning I noticed both were cooling down. The refrigerator is approx. 32 degrees and the freezer is now about 20 degrees. Was something frozen and it thawed out - or is there something that needs to be replaced?
