2017 Thor 37RB, front air conditioner won't turn on
So just verifying.... you have the FireFly panel?
Will the fan for that A/C unit manually if you try?
Reason I am asking if you have the FireFly panel is I just went through a bunch of A/C control issues with my two A/C units. It was an issue with the FireFly system and the dealer replaced the main board and the touch panel.
Here is something to try to eliminate it being a multiplex control issue. If you are on shore power, turn off the breaker to your converter. Then put the Use / Store switch into the Store position to kill the 12v power to the coach. This will reboot the system. Then put the Use / Store switch back to Use and turn on the breaker to your converter. Then try the A/C unit.
When I had control issues with the A/C happen intermittent, rebooting the system fixed it every time.... albeit temporarily until it eventually happened again.
