Mark,
The runs and the connectors for the compressors are the weak link. A couple of us have installed super heavy duty relays externally to carry the current using the original output from the board to trigger the relays. When you get the board checked out, we could walk you through the upgrade. It's killing a fly with a tank but I don't worry about the board any longer.
I know your an astute guy cause I've looked at pics of your work. You can do a quick check on the board yourself by simply using the voltmeter to check continuity from the connector connection for the compressor to the back of relay. It's pretty straight forward looking at the trace (run) on the back of the board. If those traces have continuity, then its likely one or both relays on the board are kaput. But's that's guessing without some diagnostic with the Voltmeter.
