Chris, I can't get to the "Tech - Tune Up Your Rooftop A-C" article. Is that still available?
Kind of- http://blog.goodsam.com/?p=1160, but they took my name off it, and didn't move the pictures.
The blog has been a mess for a while- I believe they are trying to clean it up a bit.
Back to the OP, the reason I say upper circuit board is that the compressor keeps running until he shuts the breaker off- classic sign of a compressor relay with the contacts welded closed.
Not that cleaning is ever out of order :).
