Thank goodness for AppliancePartsPros.com. When I queried the issue for the GE Arctica refrigerator this place had lots of folks with the same problem and thankfully the same solution--replace the damper.
I read and watched a few videos. All looked pretty simple. I took out the top two shelves and the deli drawer. I pulled off--although I was afraid to at first-- the adjustment knob that controlled the deli drawer temp, remove the light shield, and gently pulled the tower away, starting at the top. I did remove the water filter protector. It just snaps in and off. Unscrewed the top light cover and removed the cold air direction plastic at the top. Unscrewed the damper assembly at the bottom and top of the assembly. Unhooked the connection to see what the problem was. YEP! The damper door was broken,
I cut the masking tape that secured the foam insulation at the back of the damper door. I removed the damper door and its connecting pin (two parts--pin and sleeve) . I first tried Super Glue to attach the door to the pin, but this did not work. Someone was unsuccessful using a soldering gun to melt the ABS, so I wasn't going to try that. Really wished I had some plastic modeling glue, but I think those model cars, boats, and airplanes were made from a different plastic.
What was super successful was using hot glue from a hot glue gun! Worker perfectly. I only needed it to last a few days until the damper assembly arrived. I glued the pin to the door and built up the sides of the break with more hot glue. A bit like adding a weld on top. I made sure the door and female pin connection allowed for enough clearance to put the door back in. Didn't do this the first time. Reassembled the damper door and put everything back together. That top air conductor that I mentioned earlier was a bear. I just couldn't get it to slide in or connect in the same way I took it out. Bloody of a time it was. The damper was still working correctly when the new part arrived. I kept the repaired part just in case. Everything work great. Fridge is keeping at 36-38 degrees ( yea, I know, opening to door too much for those cold ones).
What I really liked about AppliancePartsPro was the model applicability app on the order page. I keyed in my model number and was assured that the part I was about to order would work. Sets one's mind at ease. Just perfect.
