I have forced air AC with a condenser outside. The problem is that I have no power at Y on the control board output to the condenser. Does the wall thermostat control this function? The transformer is good as it tests 24 volts at R on the control board. I already replaced the control board, and the new board also shows 0 volts at Y, just like the old board did, so I am inclined to think that the board is not the problem.
The coil/relay contacter in the consenser housing is not hooked up, as I am replacing it with a new one. Even so, I don't see how it not being hooked up would limit the Y voltage to 0 on the control board. But I am a total rube in this area, and could be 180 wrong.
