On many RV's the thermostats on fridge, furnace/ac are run off 12v.
Yes you tested the 12v with the light coming on but the thermostats need a full charged 12v to operate, light do not they will come on with a low battery until the battery dies.
Check the output of your converter AND check your coach battery at the battery. Any type of 'low' voltage will cause the thermostats not to work.
The heat and ac will come on but when it hits the temp set and turns off it will not come back on if low voltage is present.
Also, if you have been "flicking the on off switch on the thermostat" trying to get it to work you've put it in between the delay mode and it will appear it is not working.
1.Step away from the thermostat,
2.quit flicking the on off switch,
3.put it on the ac mode,
4.set the temp for a temp where you know it 'will' come on depending on temps where you are located right now.
5. and WAIT...for the delay to cycle.
My delay is pretty long or so it seems like it. And to this day many times when I turn it on, I still get that panic feeling that my ac is broke when it doesn't come on immediately.
