He has an 06 Travel Supreme which I believe has a 5 button thermostat unless it's
all been changed.

There used to be 2 coils Dometic used, but this is the only one I can find. Doug

9. 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.

If all your settings are correct, then the AC/Heatpump solenoid COIL is defective. 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.
Siggy

Need more info, but if you have the 5 button wall tstat, the most common cause is the Reversing valve has failed or there is NO power to the reversing valve. Dometic changed this function on the 12 button CCC2 and the default when the valve fails is to always cool. Doug
