I finally nailed this sucker - short story is that my fuse #5 blew:
fuse #5
The guy that helped me out pulled and replaced fuse #6 which controls the buzzer and the LCD temp among other things and just twirled #5. Got it running but later on I saw that #5 was sparking so I replaced that too.
This morning my TEMP LCD which had been faltering with the spring weather was on solid!
