Dometic changed this function on the 12 button CCC2 and the default when the valve fails is to always cool.

It's an easy fix if you are electricly savy. I had the same problem on my 2005 Kountry Star. See if you can find a used or new coil on ebay.

REVERSING VALVE The reversing valve is the heart of a heat pump. It changes the direction of the refrigerant flow through the coils, and changes the system from cooling to heating. The reversing valveís solenoid can be energized in either the heat or cool mode of operation. Duo-Therm roof top heat pumps have the solenoid energized in the cool mode. One method of checking the reversing valve is to feel the refrigerant line at the top of the inside coil. In the COOL mode, this line will be cool to the touch. In the heat mode the line will be warm or hot to the touch. If you do not feel a cold line in the cooling mode, the direction of flow is not correct. Check the solenoid coil for ohms continuity. An open circuit (no continuity) shows the solenoid is defective and must be replaced. dougrainer • View posts Carrolton, Texas Senior Member Joined: 06/11/2007 View Profile Offline Posted: 08/03/22 05:45pm Link  |  Quote  |  Print  |  Notify Moderator https://www.boatandrvaccessories.com/pro........DOlotPJHSwOFl50ApTlTdTimoJwaAsDqEALw_wcB There used to be 2 coils Dometic used, but this is the only one I can find.
