I recently purchased a 2015 Coachmen Leprechaun about a month ago. When I took it home, I plugged the power cable into my house and ran everything including the A/C and it worked fine. Today I went to do a few projects on it, so I fired up the generator and attempted to turn on the A/C, and nothing happened. I tried all the thermostat settings (fan, A/C, heater) and nothing turned on. I couldnโt even hear anything trying to activate. Any suggestions? I appreciate any help.
