A/C trips breaker - in cool weather
Ok, I am stumped. Our A/C started tripping the breaker 2 years ago intermittently and not often enough for me to start down the road of troubleshooting. Since then I have replaced the motor (because it wasn't completely smooth turning the fan vs our rear A/C unit and it was making some bearing noise). I also replaced the capacitor while I was working on the unit, thinking it had something to do with the breaker tripping.
It still would trip the breaker intermittently, so just before last summer I replaced the breaker itself, thinking it might have gotten worn out. We do run the front unit ALOT, after all.
Well now here I am out for one of our first trips of the season and it tripped again this morning. Here's the thing though - I think I can can say now after looking back at all the other circumstances, that it trips in "cool" weather. Or maybe mild weather, but nothing like a 100+ degree day.
For example, this morning (we're up in the mountains of NC) - we left the MH around 9am when it was in the low 70s outside and still below the set point of 75deg in the MH. When we came back, the rear A/C was on and the front thermostat indicated 77deg (above the set point) - and the front A/C wasn't running. Of course I go back to the panel to look and the breaker had tripped.
In contrast, a few weeks earlier we were camped by the lake just after Memorial Day (in our typical hot and humid southern weather) and no problems at all, even as the temps got in the 90s.
This has been the pattern in the past 2 years, would run fine in hot weather, but when we have mild mornings it will throw the breaker.
It's not a big deal at all to go back and flip a switch and go on with life, but now we've been leaving our (old) dog in the MH instead of taking him on hikes, and I'd rather not worry about it getting to hot here for him (we have the rear A/C going, but still)...
Anyways, after that long intro, would could be causing that? All of my searches turn up threads about A/C tripping the breaker in really hot weather, which is not the problem here.
Thanks!
