Sorry, just couldn't resist
Your top minds should have told me to first unplug the fridge, don't touch the compressor shell which is very hot and keep my fingers out of fan blades which are invisible because they are spinning.
The very flexible and very sticky black rubber fitting that transitions from a round opening (to mate with a tube) to a slot opening was clogged and the drain pan had similar looking particles in it.
It looked like the drain fitting for auto air conditioners.
The tube that feeds this fitting may also have been clogged but forcing air into it eventually gave a bubbling sound from within the fridge, so I guess it is now clear.
I'll know in a week or so if you guys have saved me big bucks.
In any case, muchas gracias!
