Do you have AGS enabled? If I have AGS enabled my AC won’t turn on but the fan will.

Not enough information about your 7k window unit on your 1966 Conestoga hooked to a 800w generator.
My 2001 Blazer dash air does just as you describe.


Tell us what and we'll tell you why.

If you have a FireFly Panel it could be firmware or a bad mainboard. I had this issue with my '20 Magnitude and it turned out to be a bad G7 Main Board.

You can try power-cycling the 12V and rebooting the system. You would need to unplug shore power (or turn off the generator) and then put the Use / Store (Main Power) switch to the Store position to turn off the 12V power (Main Power red light will be off). The display should be dead after killing the 12V.

Then turn the 12V back on by putting the Main Power switch back to the Use position. Give the A/C a try again and see what happens.

My system would work normally after rebooting the system but eventually the same things would start happening again (fan with no compressor / compressor with no fan, etc.) and the main board had to be replaced.

Sounds like you need a new capacitor.

How can anyone guess what’s wrong? We don’t know the year or model of the coach. Brand of AC. On SP or genny?
