Since the AC is not tripping the breaker off - I'm assuming that the compressor is stopping (the fan continues to run correct).

Sounds like it may be stopping because the internal overload (safety) has opened. If this is the case you can prove/disprove it by feeling of the compressor.

If it is kicking off on the overload it (compressor) will be 'hot to the touch.' - and will not come back on until the it (the compressor) has cooled down.

The reason for this is usually because the compressor is breaking down 'electrically,' and there is not much you can do besides replacing the compressor or the entire AC.

However, there is a chance that it's something minor like a capacitor (run or start) that is bad or the refrigerant charge is not correct.

A bad capactior will usually show a 'bulge' (but not always) - in which case if you were mechanically inclined you could (after making sure all voltage is off) remove the bad capictor (be sure you mark the wires) and take it to a Air Conditioning Supply House and buy a new one and re-install it.

As for the refrigerant charge being incorrect - you will need a Service Tech to check this out.

good luck!

RV air conditioner. Compressor running, fan stops before cool


The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.
