Heat pump failure
Looking for information here. We have an older heat pump (Trane TRW340). The outside unit no longer has the fan running, and is running on aux heat when it is kicking in. Other than that it is only blowing ambient cool air. However, I am not sure that is the sole problem. I pulled the cover off the unit and there is a 2-pair wire that looks like it should enter into the base of a control box on the compressor that appears to be cut off/snapped. Anyone know where I can find a wiring diagram, or what this actaully does? I would like to have a better idea of what is going on before the technicians show up after the holiday weekend.

couldn't locate a wiring diagram on the unit itself. The whole unit is not functioning. When it is blowing air inside you can hear a quiet whine on the outside unit, suggesting to me the fan unit could not start, however the compressor was not running either.
