Coleman Mach 15 Heat Pump
Anyone ever had this problem?
My rear heat pump (Coleman Mach 15 48000 series) air conditioning won't kick on. The unit is controlled through the coach control panel (Precision Plex control system, no secondary thermostat box). The rear room temperature as measured by the system is displayed as "COLD" instead of the usual numerical temperature. I assume that some failure of the thermostat system (wiring, sensor, control board) is indicated, and that is the reason the system won't turn on the A/C compressor. If I kick on the heat, it seems to work just fine so I know the roof unit is getting power.
