I have a frigidaire Frost Proof top freezer refrigerator. The freezer is icing up on the back wall and I am not getting cool air in the bottom part. I have used the hair dryer to defrost and then we seem to work OK for a few hours. The fan in the freezer is working.
Model is FPCI21TFW1 s/n LA02406477. Tried to locate a manual online but I haven't had any luck.

Re: Frigidaire Frost=Proof Is Icing
There is a defrost timer located in the refrigerator compartment in the area of the controls. It will be covered by a plastic panel but there will be a hole in the plastic through which you can access the clutch head screw to advance it into defrost. Turn the screw clockwise very SLOWLY until you hear one audible click. this will put the system into the defrost mode. Defrost should happen in 18-22 minutes . after the 18-22 minutes the system should automatically return to cooling. If it does not restart after 25 minutes turn the screw a little farther to the second click. If you had to turn the screw the second time to restart the cooling replace the timer.
If the system restarts automatically but does not defrost your problem is an open defrost heater or defrost thermostat. These are located behind the back wall inside the freezer section.

if ice is on the door and ceiling and frozen water dropleats on the food packages the door was left open and the air ducts are frozen.when you open the freezer door do you hear the fan blowing,if not it could be bad or iced up,if the ice is on the inside back wall of the freezer you have a defrost problem,get back to me and tell me if the ice or like snow is just on the back wall or if the door was left open ice will be on ceiling ,door and shelves and food packages,also that's not a good model number if the freezer is on top look at the left wall up near the ceiling in the fridge section,you should see a tag there with the model number.
That water is from the melting frost of the automatic defrost cycle. Their is drain in the freezer behind the back wall under the evaperator coil that is blocked, so instead of defrost water draining it's pooling in the freezer or in some case espically on models with the freezer on the top,the water is leaking from the freezer vents into the fresh food compartment. The way to clear the drain is remove back plate and remove all ice build up and GENTLY make a small hole in drain through then totally flush w/warm water. The exact location of drain is under the coil behind back freezer plate in the center. This picture may be a slightly different moldel that years but it shows where that drain is
Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.
If the evaporator coils behind the back panel of the freezer
are icing up because of auto defrost failure that will stop the circulation of
check defrost timer, defrost heater, defrost thermostat. In most newer models they don't have the timer but an electronic device which replaces the timer.
2 possible issues .evaporator fan motor is not working.you should be able to hear it in freezer.auto defrost is not working and vents are clogged with ice.look for ice/frost buildup on freezer wall///floor
take all the bottom shelves and baskets out of the freezer. look at the back wall of the freezer. youll see a block of ice in a metal pan looking part at the bottom of the rear panel. there is a hole in the bottom of that pan. thats the defrost drain. its clogged. use a hair dryer to get all the ice out then use hot water to flush out the drain hole.
Check the back wall of your freezer section to see if it is icing up. If so, you have an automatic defrost problem. One or more of your defrost components (timer, defrost heater or bi-metal) has failed. If there is little or no frost on the back wall, you could have a compressor related issue. This is often indicative of Frigidaire refrigerators. If the unit is less than five years old, the compressor is still covered under their warranty. If it is the compressor and it is more than five years old, start shopping.
