Thermostat set on auto ac turns off?

I have a 2001 Dutchmen 31S class C. My over ac works great but lately I've been having an issue. Whether I'm on the generator or plugged in my ac while in auto mode will turn off if u turn a light on. It's almost like its reached its temp and shuts down. It will turn back on after a few min. If I have it on regular mode not auto it's not an issue. Maybe thermostat or inverter problem? Anyone had this issue before?

It's most likely not in the inverter. So you can avoid having to look there. You would not have enough battery power to run your A/C off the inverter.

More likely it's a low (12 volt) issue and I would start there. Most of the lights in your rig would be run off a 12 volt circuit. If you can determine if all lights are causing the same problem then its most likely the thermostat not getting enough current when a light is turned on. Might be as simple as dedicating a circuit just to the thermostat or maybe your batteries are getting old enough that they need to be replaced. Have you replaced your "house battery" since you have owned the 12 year old unit?

Yes, it only has one Optimo blue top battery and its less than a yr old. This just started few weeks ago. As cheap as thermostats are maybe ill go that route. It's the original style prob 12yrs old
