My heat pump only blows cool air in heating mode. Is the reversing valve bad?

Maybe, but check the coil first. The solenoid coil slides off the valve body, is sold by itself, and fails far more often than the valve does. Pull it, ohm it, and confirm you have 24 volts at the coil when the thermostat calls for the mode that energizes it. Open coil or missing voltage means you are buying a coil, not a valve body and a day of brazing.

How do I tell a dead coil from a stuck slide?

With the system running, pull the O or B wire and see whether the valve shifts. If you hear it thunk over and the pressures move, the coil and the control wiring are fine. If the coil is energized and nothing happens, hold a strong rare earth magnet against the body and watch whether the internal slide moves not at all, partway, or all the way. That separates a mechanical problem from an electrical one.

The valve shifts, but the heat pump is weak in both modes. Now what?

Check for internal bypass. Compare temperatures hot line to hot line and cold line to cold line at the valve. More than about 3 to 5 degrees difference means refrigerant is leaking across a slide that is not seating, and the body has to come out.

Is O energized in cooling or B in heating?

Depends on the brand, and it is worth confirming before you condemn anything. Most manufacturers energize O in cooling. Some older systems energize B in heating instead. Read the diagram on the unit, not the wiring the last guy left.
