Dave G Rigby , ID February 02, 2024 Appliance: General Electric Refrigerator GSH25JFXBBB Ge Refrigerator Gsh25jfxbbb: Refrigerator was 20 degrees. How to replace Refrigerator Damper Cover Assembly. The old damper cover assembly was a non-motorized mylar plastic damper flap. It would not close with the new control board and new evaporator fan motor. Installed new damper cover assembly with a motorized damper. So the damper closes at preset fridge temperature. Now the fridge works like it is BRAND NEW!!
