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 i...

Things to check
I've found many RVers have a few screws loose.. With shore power OFF and Generator OFF grab a flashlight and a Screwdriver.. Most likely a #2 Square. and tighten every screw in the breaker box/power distribution panel.
One of mine took 3 1/2 turns
Another RVer found a wire-nutted connection likely at the A/C's junction box that needed to be re-done. I'm not a big fan of wire nuts in RV's.
if it runs for a bit THEN trips the branch breaker..
I have the ability to easily monitor overall current (Branch current too if I need to but not as easily)
As the unit runs the idea is to pump refrigerant into the condenser where it sheds heat to the airpassing through and is "Condensed" but if the condenser is all clogged with stuff like Cotton wood Cotton or other **** that's in the air then air does not flow fast enough to cool and heat builds up. pressure builds up The Compressor works harder and as it slows down current goes up (That's a college course to explain) and CLICK goes your breaker.
Most (Other than Coleman) the crud is on the fan side where you can't see it (Coleman sucks air in via the condenser)
There are other possible issues as well.
