Chester,

Thanks again for the clarification.

I am not disputing your conclusions, but I am terribly bumfuzzled and perplexed by the situation. I am not an electrical wizard by anyone's imagination, so I am asking for help understanding this one.

What in the circuitry or the thermostat could possibly cause the compressor to only pull 4 amps? Either the relay on the board closes or doesn't close to provide electrical continuity to the compressor. It is obviously closing, since the Number one circuit provides power to either compressor attached to the number one circuit. The circuitry turns the power on or off to the compressor, there is no mechanism for limiting the current that I am aware of.
