My freezer quit working and fridge got to warm. Fan is not running but the compressor kicks on when I turn back on. Now after a day I am finding that I have to defrost again. What parts do I need?

Son left freezer door slightly open. Freezer cold but frig warm. Took covers off coils - found completely iced over. Thawed coils with a hair dryer - heard a sound of a damper popping open or closing. Reassembled everything. Four days later same problem - warm frig. Thawed coils again. Heard the same damper sound popping. Ohm checked heater - 29 ohms. Not sure if its heater, thermostat, or board.

A while back, the compressor on this unit ran all the time. I replaced the freezer thermistor and all was well until recently. Now I hear a fan running all the time. The temps in both freezer and fresh food sections seem fine, and when I run the diagnostic tests everything tests OK except that the defrost test shows the defrost thermostat always shorted (closed), and I am not sure if this is normal. The temps seem fine and I see no ice build-up anywhere, but I hear a constant fan running. I think it might be the evaporator fan, and don't know if that is a problem or not.

Freezer is not keeping ice and items in freezer frozen all the time. Sometimes it is fine then others there is water in the ice bin and popsicles are thawed out. Other times things in frigerator will partially freeze. Compressor appears to be working as well as fans. We have cleaned out the coil.

Have 5 yr old fridge. 3 months ago the coil iced up and the fresh food side got warm. I unplugged for 2 days - turned back on and it was ok again. 2 days ago the coil iced up again. I was in process of cking ohm resistances when the fan and comp shut down and the heater heated up, defrosting the coil. So I am assuming that the heater, thermostat are ok. But why does the coil occasionally ice up and cause fresh side to get warm? Intermittent signal from circuit board?

In last 3 months My freezer coil iced up 3 times. 1st time I thawed it 2 days and it was ok after that. It happened again and I was in process of checking continuity when the fan shut down and the unit went into defrost mode. The heater kicked in and it defrosted. Seems to me that all 3 "normal" parts of the defrost system should be ok. Why, then does the coil occassionally ice up - causing the fridge to get too warm? Could it be that the ADC is intermittent? Or maybe the "tight" space the fridge fits into is a problem? Fridge is only 5 yrs old.

I have a maytag side by side fridge that doesn't hold the freezing cycle: @ 0 hour - compressor kicks in and runs. @ 1 hour - compressor runs, evap fan runs, frost on evap. @ 3 hour - compressor runs, evap fan runs, evap is warm. @ 5 hour - SAAB I changed the defrost thermostat, the ADC and the same behavior and it does not maintain freezing point 0 celcius? I checked the harness of cables and the circuit is closed. Could it be the defrost bar? During running, I lower cold control

My refrigerator is only 13 month old. The back wall of the freezer is building up ice and the upper part of the refrigerator stop cooling. I removed the back wall and found complete ice buildup. I thought the fan that routs the cool air up from the freezer was defective but is not so. After doing a bit of research, it can be one of the next components: the defrost thermostat part # AP4009169, defrost heater PART # AP4078434 or the ADC(control unit)part# AP4366538. Please advice.
