    Welcome to the Portal from South Carolina. It may need the Freon checked, at its age.

    It can be several things. First it needs power from the thermostat (the dial). Next it checks that there is freon pressure (very low pressure it will not turn on) via a low pressure switch. If pressure is above some low threshold it sends power to the compressor and cap. Can you hear the compressor kicking on?

    The capacitors would be the first thing I would check.

    Can you hear the compressor kicking on?? If it kicking on an stays on its mostlikly low freon.

    Most RV AC units do not have ports to check the refrigerant.

    RV systems do now have charge ports. No way of knowing how much refrigerant is in the system. Ports can be added. Neither do they have low or high pressure cutoff's.
    Can you hear the compressor kicking on? or running? Might be worth having someone who does HAVAC look at it
