Temp does have something to do with it. At higher outside temps ac runs
higher pressures. Takes more current to start the compressor. AC
copmpressors have to start under a load so they need a lot of current
initially. First make sure you have the correct circuit breaker. Then
replace if it's old it cause when they get old they blow at lower than
rated. Voltage brownout will do it as well. Check and tighten all the
connections. None of that works call the service guy cause you're
probably not qualified to go any deeper.


Exactly. The problem with these rigs when used in travel trailers is the
poor insulation of the trailer itself. On hot days the temperature can rise
back up over the thermostat setpoint before the head pressure bleeds off.

But, I am willing to be his problem was low RV park voltage.

I'm hoping you're correct!

But, I'll probably never know for sure. Maybe the dealer will find a
bad capacitor or something. But I'm going to change the circuit
breaker first.

Easter egg hunting is not a good troubleshooting method, and it could
get costly.

You need a good multimeter that is capable of reading at least 30 amps
AC and AC volts. Keep in mind amps are read in series. Meaning you have
to break open a circuit or use a clamp on pickup or if the Air
Conditioner unit plugs into an outlet, instead of being hardwired, you
can use an adapter with the clamp on pickup or a killowatt type of
device to take readings.
