Air Conditioners and Really Hot Weather
We have a 2009 Mandalay 43A with three rooftop air conditioners. While at the Colorado River a few weeks ago with outside temperatures exceeding 110 degrees, the air conditioners started tripping thei...

I assume you meant you are tripping branch breakers This happens for one of several reasons and .. .they may "Cascade" (that is one leads to another) As I am dealing with it as I type.. More later.
First: All my A/C's (total 4, though only 2 at any one time) if the condenser coils get clogged and air does not flow.. What you got is what I had. Now for most A/C's you go topside as the song says "Up on the roof" and remove the outer shroud. (Coleman go to "Skip)
THen you need to remove an inner cover over the Condenser. this may involve anything from a few screws (Carrier for example) to cutting some metal tape and bending tabs (Advent air.. NOTE you can only bend tabs so often).
Now if you have dainty hands like mine (XXXL) you need to remove the fan. Usually this involves a pair of common pliers and a spring ring. Sometimes screws or bolts.
(SKIP POINT)
Now you can clean the condenser (NOTE you can inspect w/o fan removal)
Also compressed air may blow it clean without fan removal (Except on Coleman)
I do not recommend water (Mell of a hess that way)
Coleman is different because though most A/C's BLOW air through the condenser. Colemans Suck it in
ON my coleman (And my Modified Advent) I remove the outer cover, peal off the cottonwood, and replace the outer cover. (The mod,,, Wheb the made in china fan turned into a china bomb and went BOOM (I do mean BOOM) I replaced with a COLEMAN fan. fits perfectly and SUCKS instead of blows WOW).
Next. A bad motor can crank up the amps
And finally.. I am told by wiser heads than mine a bad Run/Start cap can do it. Replacement on order, Install set for Week from Thursday.
Finally...
As heat builds in the system (OR for that matter outside the RV) the pressures in the system increase. as the pressure builds the compressor draws more and more power tilll........ CLICK it stops.
