I have a GE side by side model TFS28PBDA BS , serial number SZ202273 fridge.
I noticed a few days ago that the DE diagnostic light was flashing. Today, the whole fridge compartment (right side) warmed up. The freezer side is fine. I pulled the fridge away from the wall and vacuumed up. There is a fan near the bottom blowing out warm air. The freezer side makes the same noise as it always has. I hear a fan running. There is a slight fuzzy ice buid up along the back side of the freezer. I don't know how to check the freezer coii or where it is for that matter.
Thanks for reading,
