HVAC - No Compressor run
The Coleman Mach 3 13.5 BTU HVAC has worked perfectly from 2008 until now. Troubleshooting my RV HVAC unit. The thermostat says COOLING ON. I have fan control from the thermostat, but no compress...

A new thermostat arrived today and I installed it. The new one is similar but not the same as the older unit. I now have B+Voltage on the cooling request line but now it's the board that is not functioning correctly. Just ordered a new board and it should arrive in the next week or so. Might even get an RV trip in after the HVAC is running again. Wouldn't that be nice?
