I have a mach 8000 series when I'm driving my motor home

Customer Question

I have a Coleman mach 8000 series when I'm driving my motor home with my genset running my rooftop ac blow warm air. But cold when parked? Every thing is clean and running properly. Which way should the fan be drawing air through the condenser coil? In from the back or in from the sides out the back?

If I understand you, if your run the generator while driving you get warm air. If you park and plug in its cold?

Customer: replied 1 year ago.
that is correct. But when I'm parked even with genset it's cold. Always cold parked shore power or genset?
