On my newer CrapAir unit, it appears the reversing valve is stuck. It will operate and blow heat like I've died and gone to hell, but it won't go the other direction and cool. Condensing unit runs, but just won't push the gas back the other way. Unit was new in December 2007, so I think it might still be under warranty, but I can't find a competent CruisAir-approved technician for warranty work in Miami. I've asked CruisAir for advice, but I'm still waiting on a response. Do you guys have any clue as to how I can fix this myself? The magnetic coil in the solenoid valve wasn't working, and I've just put a new one on there...still no joy.

Whatever happened to "quality"? My 29 year old CruisAir units look great and run like Olympic champions - the new CruisAir stuff is crap and has brought me nothing but torture and grief.
