Thanks for replying Doug,
I got a no power indication at the reversing valve coil.
I checked the relay feeding the reversing valve at the inside control board. I got a no power indication at that point.
I put a jumper,(from a known good 110v power source on the compressor relay) over to the load side of the reversing valve relay to feed the reversing valve. The reversing valve clicked when energized, so I powered the unit up and and it cooled normally.
I assume at this point that the relay controlling the reversing valve is bad. The fix would be a new control board as I see it at this point.
thanks for your time, help and knowledge,
Bruce
