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.

That's what I said yesterday. Congratulations.

John, I take it you're talking about your auto air conditioner?

What make and model?

No, Tim, it's one of these buggers: http://tinyurl.com/69jflb

The one on the trailer. Once the outside temp cooled down, in the
evening,
the AC ran fine. But during the hottest part of the day, the thing would
trip the circuit breaker no matter how we adjusted the settings. I found
a
web site, so I'll do a little research.

Call the dealer. It's got to be still covered under a warantee.


I did. In fact, I stopped by the dealer on the way back. He said if the
system showed no problems when they ran it, and the outflow was twenty
degrees cooler than the inflow, then they'd do nothing more. Needless to
say, I got a little hot.

John,

Here's what little I know about air conditioners in RV's and TT's.

On hot days, the head pressure will be highest in the compressor. If it
cycles off, then tries to start again before the head pressure bleeds off,
it can trip the breaker due to excess current draw. This is why many air
conditioners have a label indicating that you should wait 3 min. or so
before trying to restart. Some AC units, particularly central air systems
have a time delay built in to prevent the compressor from trying to restart
too soon.

If it was as hot as you indicated, the lack of insulation in your TT could
lead to the AC unit trying to restart too soon.

If the problem is due to a general voltage droop in the RV park you are in,
you can solve that with one of these:

Thanks for the info.

I guess I need to carry the multimeter in the trailer when I go out.
Didn't have it this last time, but I'll have it from now on.

My first stop will be to get a new circuit breaker.

Check for low freon, it may be freezing the coils up.

He would have little or no air flow if that happened.

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.

I think your warranty would be expected to cover that. I wouldn't start
monkeying with anything until that warranty period is up.



Let me see here. You're outside, inside a metal sardine can, in a trailer
park full of other metal sardine cans. You're all hooked up to the trailer
park's wiring, and you all have your air conditioning on. The voltage is
dropping.
Hmmm.



That's what I had happening with my old 35' Chris Craft at our marina. Too
much draw on old, corroded wiring (marina wiring that is).

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.

Entia non sunt multiplicanda praeter necessitatem.

The simplest solution is usually the best.

For a guy who claims he has an engineering background, Herring surely is
unscientific.

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.

Seems to me that when you first had this problem we talked about undersized
extension cords, undersized house wiring, defective breaker in RV, and low
voltage. As I recall, your AC started working and the issue was dropped.
Someone said head pressure will increase as ambient temp increases. That's
true. So now you have at least 5 potential reasons why you are popping the
breaker in the RV. The reason the breaker popped at the campground may be
different than why it popped at your house, but let's assume the reason is
the same.

I think I have laid out the situation properly. If not, correct me.

I know there are at least 4 or 5 guys here that would be able to put you on
the right track.

Would you like some help to resolve the problem?



The problem may have been due to the heat, but I don't remember the
temperature when I first had the problem. Most folks thought the problem
then was caused by having the trailer connected to house wiring (20 amp).
But this time I was connected to 30 amp. I'm thinking that outside temp may
be the common theme to both problems.

Sure!



I thought you were an engineer. Any graduate engineer should be able to
figure out a simple electrical problem. Even an English major grad could
do that.

No wonder we lost that war.
