A bad capacitor can make an AC operate like Jack Nicholson had the wheel. Check starting current of BOTH the compressor AND the motor that powers the condenser and evaporator fans shaft.
Manufacturers should be FORCED TO make the so-called "Hard Start" capacitor standard equipment. OEM can buy stuff for about 20% of what we mortals are forced to pay.
Is there a way someone like me, with only a multimeter can check this and if so, how? Otherwise, should I just take it to a shop to have this checked?
The model number will tell you if it has a hard start capacitor. BUT, RVP only specs out hard start capacitors for Major OEM RV makers, when asked. Small van conversion companies or RV after market suppliers will not stock RVP AC units with the hard start capacitor. SO, you need to install one, especially if you are using a NON RV generator for power. Using the type Genset you have, the Hard Start Capacitor will make all the difference in the world on start up. As to being "forced". BS. The Non hard Start units will function just fine with the intended 120 supply either from Shore or from a RV designed Genset. THAT is the correct answer. If you USE a RV designed genset, then the Hard Start is not needed. Use another type genset or power supply, then YOU need to install the required updated Capacitors. Why should the majority have to pay extra for the small minority needed equipment?????? Doug
