if this has only one evaporattor coil then you wil have to turn down the freezer too. first check to see if the if the manual damper motor is working properly. turn the tempertur to 0 on the frig and the damoer should close down. look to see if it did. then turn to 9 and you should hear the damper motor opening and feel air from the outlet.

It is an error code. The thermal fuse in the freezer section has gone. It has to be replaced. To get by in the short term, uplug the unit for 15 minutes, then plug it back in. It will run until it hits the defrost again (approx 5 hours) Part location is 401A and part number is 6615JB2005C. It is easy to change once you get the back cover off. Plug in part.

Check in the back of the fridge section; there is normally a control that is provided for 'balancing' the cold air between the two sections. That coolled air is distributed by a concealed fan that may not be running; you should be able to ear or feel the air movement when the unit is in a cooling cycle.

Do this when the refrig starts to warm up . Don't defrost before this test .
Pull the refrig out and remove the 8 " x 10 " panel . Behind this panel , is the main control board . Unplug the refrig . Remove the BLUE plug from the board , with 3 larger wires going to it . Looking at the blue plug , the sequence will be wire1,wire2,space,wire3 . Get a short piece of insulated wire , and strip about 1/4 inch from each end . Insert 1 end into wire2 , and the other into wire3 . Plug the refrig back in . After about 3 min , look in the freezer , at the bottom , behind the crisper , look for a red glow . If no red glow , unplug the refrig , and reassemble the plug and cover . This no glow , indicates a shorted defrost heater WR51X10055 . It is also advisable to replace the defrost thermostat ( pt. number WR50X10068 ) when replacing the heater . To access these parts , you will have to remove the inside rear wall of the freezer . The heater , is at the bottom of the coils , held on with 2 screws , and the thermostat , is the 1 " cylinder , with a blue and pink wire going to it , clipped on the top left of the coils .
If you do get a red glow , then the # 4 thermistor is bad . This tells the main control board , the temp of the coils , if they need defrosted , when they are thru defrosting . This thermistor is the 1 " long , torpedo looking piece , clipped on the top left of the coils , with 2 white wires going to it . Part number WR55X10025 . It would be advisable to also replace the # 5 thermistor , located at the bottom of the freezer , slightly in front of the drain , also with 2 white wires going to it , slid into a housing . This thermistor , is the freezer thermistor , which tells the control board , the freezer temp and when to cycle off due to selected temperature .
