    If the compressor started 7 min after the condenser fan then the compressor is at fault. What is the amp draw of the compressor running? Also does it make any noises before it starts, if it does whats the amp draw. Sounds like it maybe a no pumper if the pressures stay equal.

    Also, no king valves, just regular. The unit would not pull down below 60,with the high side shut. Both valves were fully open to start.

    Also is this a heat pump, if so remove the O wire and see what the pressures do maybe the reversing valve is not all the way in cool mode

    I didn't do an amp draw after the behavior of the compressor. Sounded fairly normal on start-up. I did an amp draw before the compressor came on and it was .09, for the fan.
