Freezer And Fridge Both Getting Warm

According from the model number posted above you seem to have a side by side refrigerator, is that correct? If so, often when your refrigerator is not cooling, it could have floating restriction in the line or something more complicated like an issue with the sealed system that only a professional can repair. This can include the compressor not working, the evaporator fan not turning, or even coolant in the lines at incorrect levels to properly cool. If the compressor is running, humming, or even a little warm that is typically normal. I suggest cleaning the unit out including the coils you can reach (typically located in the bottom behind the toe grille) and make sure no food items are blocking any vents in the unit. Also try checking and see if the door seal is bad; place a dollar bill between the body of the freezer and the door. Now close the door. The dollar bill should stay in place and pull out with a small amount of resistance. If the dollar bill falls out when placed between the gasket and cabinet double check to see if the door is being blocked by anything stopping it from closing. If any of these suggestions prove to be ineffective, connect with a professional to accurately pinpoint any potentially more serious issues.
