OK... so the air conditioning stopped - but you still has power for other 110v things (microwave, TV, etc)...
I am assuming only one A/C unit in the rig?
If plugged into the pedestal - the breakers on the generator aren't in play
If only the A/C is not working - I would start with the thermostat. As you slide the temp gauge down - you should hear it click on.. (Note that many thermostats have a delay that once the A/C is on - and turned off - it won't turn back on for 2 min. This is to protect the compressor which can be damaged applying power while still under pressure from previous run.)
Does the A/C fan work? (just not cooling? or nothing?)
Should help point us down the right direction...
