A/C tripping breaker
I have a Fleetwood Expedition 36t with 30 amp service and the power management system. Up until recently I've been able to run both a/c's without any problems all day long. Now I can't run both withou...

Hey guys, I'm still fighting this one. I removed the roof cover and inside cover and cleaned both coils on both units with coil cleaner. I monitored the amp draw before and after the cleaning and saw about 1 less amp draw per a/c unit. The coils were past due for a cleaning. With absolutely nothing else running both a/c's are drawing around 28-29amps. After some time running both front and rear I'm still eventually tripping the breaker.The ECM is working as it should because if I switch the fridge on ac power it will shut off the rear compressor and indicate shed on the control panel for the rear. Last year I burnt up a start up capacitor. I know they have start up and run capacitors. Could the run capacitor be getting weak and causing more amp draw? Would a weak run capacitor be less efficient as the unit gets hotter increasing amp draw causing the breaker to trip?
