On the inside the fresh food section usually on the right wall there will be a model number near the top.
I took off the bottom front vent and it was full of dust and gunk so I cleaned that out hoping that would free up airflow. I didn't see the defrost timer there or in the back by the compressor. What I see is a compressor, a fan that has some kind of a power unit of the like attached to it and wires that go up into the right wall of the fridge as you face it from the rear. It has wiring like a car where a number of wires go into a single plastic clip and then into some component.
I cleaned everything out of the freezer. There was frost on the thing that goes up the middle back of the freezer and seems to cover the fan. The fan didn't look or sound as if it was running though. I cleaned that all up, replaced the food into the freezer and started the ice maker and that worked still.
Any other ideas where I might find the defrost thingy or something else to try? Would the defrost timer keep the fans off? I did find a wiring schematic when I pulled off the front vent and it has part(NNN) NNN-NNNNA on it. It has not part listed for the defrost timer, but says the part can be found on the component. Does that mean it is attached to the compressor somewhere?
is this getting cold at all at this point? let me know . Bryan
