Thanks for the feedback everyone.
I'm sure the coils are as clean as they can be. They weren't too bad to start with, but I used a shop vac with a brush attachment to get the few items that were large enough to see. I then soaked them with a foaming coil cleaner and finished them off with a good rinse with the water hose. I did this with both sets of coils.
I don't think it is the supplied voltage either. I have had the same issue at 2 different RV parks, using the generator, and plugged up at my home.
I'll check the amp draw using an extension cord. That should tell me something. I don't think the coach has the amp draw on the EMS, but I know where I can borrow a meter.
With the additional info you are more than likely looking at
replacing the A/C . You know its drawing excessive amps
because the new breaker trips .
You have already gotten more yrs of use than most .
Be sure the new unit will communicate with the thermostat
and the other A/C or go ahead and replace both units and
thermostat .
That's what I did , 2 new A/Cs and thermostat .
I didn't really want to spend the money but DW said I ain't
going if its hot in there . Glad I did now .
