Well, I pulled the refrig out and I may have resolved the problem.
First thing I found was that 25cent piece of cardboard with the 3cents worth of insulation that covers the section where the compressor and coils and fan are (that they want $72 to replace!!!!!!!!!!!!) wasn't attached.
Then I took a vacuum and tried cleaning the coils which is just about impossible, especially the MIDDLE row. I finally took my compressed air blower and just hit it with all it had. Even with that it still wasn't able to full clear the middle row of coils but I got 90% of all the gunk from under the refrig (which is now blowing all over the house!) and it looks like new

It seems right now that the hot spot is mostly gone. I THINK it was more from the lack of the $72 cardboard cover (worth 28cents or less) not keeping the fan air circulation under the refrig circulating.
We'll see how it goes in a few hours.
How do you get the condensation drip pan out of this thing? I'd like to clean it out. I can't figure a way to remove it either from the front or back.
Thanks to everyone for all your help.
