How to Troubleshoot & Replace Ge AP5712604 / WR02X20092 Foam Duct

My friends think I am awesome. To them a refrigerator is complex mystery that only highly trained technicians can tackle. But really this was simple. The hardest part was removing all the food and then replacing it. I am glad I fixed it myself and saved tons of money over the cost of a new refrigerator. 

1. Locate 2 screws at the base of plastic duct that covers fan in freezer 2. Use a Phillips head screwdriver to remove the two screws, and set them aside 3. Carefully slide the duct up toward the top of the freezer (for top-freezer units) and remove by pulling toward freezer door once it is free of the brackets holding it in place. This will expose the duct foam. 4. Lift duct foam from the duct 5. Place new duct foam in the duct 6. Carefully replace the plastic duct. It should be firmly attached to the brackets in the back of the freezer, and also cover the duct foam completely. Do not use too much force, as it may damage the new foam. 7. Use the Phillips head screw driver to replace the two screws 8. Check to make sure that the plastic duct is flush with the freezer, so that the air is directed correctly.

Replaced fan and duck...I'm 90 miles from any repair service. 

I followed your repair video to pull the power plug & empty the freezer, remove the rack, remove the fan cover, also removed the foam duct behind the fan cover. Then I removed the wall back panel, also removed the fan blade clip to release the blade, disconnected the ground wire to the fan motor bracket & the two bolts holding the fan motor in place. Then disconnected the fan connector & removed the old fan motor. Then I installed the new fan motor & all parts in the reverse to a perfect install.
