The fridge is not cooling, but my freezer works great?

Check under unit and clean coils. Remove rear cover (unplug first) and wash out coils and vacuum up water. Use a sprayer on water hose to clean coils, keeping water out of fan motor. Clean fan blades, too, with Windex or other cleaner. After doing this let us know how it works. Make sure to replace rear cover, and clean coils each 6 months. DrTom4444
