Yesterday I asked about why my freezer was at the proper temp (o deg) but the fridge was around 45-50. Your response was for me to remove the auto damper assy part# AP4070404 to allow cold air to enter the fridge from the freezer (interim fix) so I could further test the damper assy. I removed the damper assy but couldn't figure out how to allow cold air in. I did feel cold air come in when I opened the freezer side, but when I closed the freezer, the cold air flow stopped. Do you pull on a damper door or does it slide? I'm guessing that this is what the spring is connected to.
To further diagnose what the issue with my unit may be, I forgot to comment that initially the freezer had come ice build up on the back wall. That went away when I unplugged the unit overnight. As a result of seeing other questions similiar to the symptoms that my frdge is experiencing, and based on your response/s, it looks like I may have an auto defrost problem and not an auto damper proplem. How does the auto defrost affect the temp on the fridge side?
Thanks for your time, you guys are great.
Answer Hello Joe. If there is a defrost probelm, the coils freeze over and air flow is restriced to going inside the refrigerator. If so, you will need to test the defrost heater and the defrost thermostat 61006198. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer 61005988. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
There is a loud buzzing noise coming from this part. Would you suggest replacing the entire assembly or could it be a seperate part that would cause the buzzing noise?
Answer Hello Dave! Check the damper assembly and see if the noise is coming from there. Here are the instructions from the manufacture. Hope this helps. Checking the Auto Damper 1. Disconnect the unit from the power source. 2. Open the fresh food door and remove any items on the top shelf. 3. Set the fresh food control to the coldest position. 4. Remove the light shield cover by pulling down on the back corners of the cover and sliding the cover forward. 5. Remove the fascia/radiant shield mounting screws. Remove the control housing mounting screw at the back, bottom center of the control housing. Slide the control housing to the right. Lower the control housing. 6. Disconnect the temperature control housing electric quick disconnect. 7. Remove the temperature control housing from the refrigerator and place on a flat work surface. 8. Remove the auto damper control rod retainer, control rod and the slide control gear from the auto damper control. 9. Turn the control housing over. 10. Remove the two auto damper mounting screws, then remove the auto damper from the control housing. 11. Mark the auto damper rod approximately 1/4" away from the housing. 12. Uncoil the auto damper capillary tube approximately four inches. 13. Submerge into a glass of ice (no water). Watch for door to move to the closed position. 14. Remove from ice and warm capillary tube (use your hand). Watch door for opposite reaction. 15. If no movement is detected, replace the control.
