Hello,

I too am trying to go through the 3 stages of figuring out which part of my defrost system is broken. My frig is warm, the freezer is working fine. I cleaned off all of the frost behind the freezer, and it is coming back quickly so that cold air is no longer going up to the frig. Any clues about the location of the part?

I tried looking at the diagrams but still cannot figure out where it is located. I see a black box under the bottom freezer, but not sure if that is the high voltage box/condenser. Does the defrost timer look like a computer control board? The names of parts aren't consistent, so I can't tell exactly what it is called and its location. It is crazy making! What and where is it????

Thank you so much for your help.
