How to Troubleshoot & Replace Ge AP4363289 / WR17X12490 Cover Evap Asm Ff

Changed cover / evaporator unit (could have salvaged the old one but it had a lot of black mold and not worth effort. Replaced drip pan (Note: going forward I will do preventive maintenance and replace this every 3-4 years whether it needs it or not) Took apart other parts with mold and cleaned/replaced 

Purchased a relativly new ge stainless profile fridge from crisis list. Was having problems with it cooling. Found out someone had replaced the fan with a pc fan that didn't fit and the coils were freezing over. To make matters worse rust from the fan clogged the evap drain. Purchased replacement part from here and was able to easily replace everything with just a screwdriver. Very easy to fix and the fridge is now problem free. 

I replaced the cover w/fan that is over the condenser coils and drain pan underneath that structure. 

The trough drain was rusted through and the Styrofoam on the evaporator was moldy. So, I replaced the entire cover and trough. I unscrewed the three screws on the cover. Unplugged the fan and removed the cover. Three are two more screws holding the trough and evaporator, I unscrewed them and removed the trough. The hardest part was cleaning up all the rust. Once it's clean, put it all back together. I was easier than I expected.
