I'm thinking my damper door is not opening far enough. How far is it supposed to open? Part # 8 And for the thermostat thermocouple for the freezer control, Part #3, do you just stick it in the hole or do you route through the cover to get it closer to the damper door inside the freezer section?
Mine is only opening maybe to 45 degrees - 1/2 way between horizontal and vertical when warmed by hand.
My freezer is 10 degrees, my frige is 48 degrees.
Based on the information it sounds like the damper is open properly. The thermostat does get routed through the housing then out by where the damper door is located. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. 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 control. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
