Frigidaire Side by side Not cooling

Frigidaire side by side Model#FRS3HR35KB fresh food side was over 60 degree and the beer was getting way too warm. As well as the Cherry Garcia ice cream melting like it was a hot summer day. But this is November. Time to call for service.

when I first arrive I see the back wall of the freezer side covered in heavy frost… Thinking it is one of the Frigidaire side by side that red heater plug has filled with water and separated that causing the heater circuit to by open. I remove the four screw that hold the evaporator cover on and slide it out. Too my surprise the heat was plugged in. but that was heavy frost all over the evaporator.

So I decided to put it into a f orced defrost by pressing the light switch on and off 5 time in 6 sec. the compressor stopped and the damper pn#241600902 closed and in just a minute the heater started to make  a clicking noise  as the calrod heater started warming up…This indicates that the heater circuit is good ..Defrost thermostat, Heater and wires to them.. I need a Adaptive Defrost Control PN#241508001 it is a electronically controlled defrost timer it keeps track of the period between defrost cycles, the time duration of the defrost cycle and how many times the doors are open. The device is programmed to keep track of the appliance usage and how long it takes for the evaporator coil to be thoroughly defrosted. It will then calculate the amount of time required and Adapts itself to be effective to save energy.

Removed the damper/ADC cover assembly by removeing the three screws across the front control box and the two screws located in the rear control box. The 2 housings will separate at the left back of the front housing by sliding the rear housing to the right until the buttons line up with the larger hole in the slots. Two screws later and the ADC was replaced and ready to go back. replaced the cover and the beer will be cold enough for the Ducks football game.
