02 suncruiser,
Did they tell you which reversing valve is bad? There is one for each compressor.
If one is bad, (stuck in cooling mode), you should be able to run on the other one. Just trip the breaker for the unit which is bad.
If they are saying both reversing valves are bad I would look more at the PC board relay as being the culprit, or the tstat.
Hard for me to believe that both reversing valves would go bad at the same time on a unit that new.
