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.



Heh .... I drafted a post for John, describing the old Navy "Easter
Egging" technique of troubleshooting,
and recommended he do a more logical series of tests, but then I
realized that people need to do what they need to do, so I deleted
the post.

I doubt very much his circuit breaker is bad. Could be wrong, but
there are other things I'd check first.

But, I have a feeling he's going to claim the problem as being fixed
after he replaces it. For a while. Then, sometime in the future
when conditions are similar to that he wrote about, the problem will
return.

Give me a break! I don't usually make a lot of claims that aren't
true. Perhaps you're confusing me with someone else.

The new circuit breaker costs $12 bucks. I won't know if that's the
problem until we get another 95 degree day. If the problem returns,
then I'll know it wasn't the circuit breaker.
Unlike some other folks, I have no problem with being wrong. If the
problem reoccurs, I'll let you know.

I think he meant because of cooler weather, you will think it is cured.


Herring was an injineeeear but doesn't know anything about electricity?

Goodandplenty, goodandplenty, goodandplenty. WOOOOO- Wooooooo!

Yep, he was an engineer, alright.
