Freezer wont defrost and refrigerator is to hot

the evaporator coils in the freezer are iced up. either someone left the door ajar for a while, you didn't let the fridge sit empty and turned on for a day before filling it, there is an obstruction in the evaporator drain causing water to pool and freeze on the coils, or your evaporator fans are not working. you need to unplug the unit and either: 1- let it set with the doors open and defrost with the ambient air (and soak up the excess water under the fridge); 2- find the back wall where the frost is, take the screws out and remove the wall, and use warm water to melt the ice on the coils (and soak up the excess water); or 3- use hot air (hair dryer). be careful with the hair dryer. just enough to melt the ice and not to heat up the fins and tubing. clean up any extra water inside, check the drain under the coils for obstructions, make sure the fan works, empty the fridge, turn it on, close it, and fill it tomorrow. also, there is a self-defrost timer on the fridge. look in the manual for it's location and setting.
