Question about Gibson Heating & Cooling
A technician replaced the capacitor on my air conditioner a couple of years ago but also added a 2nd capacitor connected to the fan side of the main capacitor. I am guessing he just didn't have the correct capacitor. Compressor won't start again so I want to make sure I get the right one. Currently the main capacitor is a Packard PRCFD 805 80+5 MFD with a 3 MFD added to the fan side. Is this the correct capacitor for the unit?

Obviously the 80 part of cap is for compressor if the motor was not changed it should still be a 5uf. new motor require different values.

you may have a factory defective unit that is not turning off the anti-frost heating coil (I have assumed yours contains this item based on your problem description). I would trade it in for a new unit, again assuming you have a warranty or the store offers a good in-store return policy. If this plan bombs, then open the unit and find the heating coil near the cool side of the radiator fins. then disconnect the power wires to the heater and prevent electrical short to wires with quality electrical tape.

You hear the compressor kick in (Hum) but no fan comes on? Will the fan come on when just in fan mode, not cool, or do you have that set-up?

Purple should be on "C".
The fan motor may be destroyed now. Switch the wire and see if it keeps running or not.

It sounds like the unit was miswired at the factory, since when the A/C is "off" at the thermostat, there should be no calls for cooling or for the fan to run.
You also stated the most puzzling issue, with the breaker turned "off" the same thing happens. This shouldn't happen at all, when the power breaker is turned off, there should be no power being supplied to the unit and it shouldn't be able to do anything. Very strange indeed, but likely a major error done when the RV was manufactured, or some wiring in the loom has somehow become shorted and is supplying power from another breaker/source.
I think a call to the manufacturer is in order since there is no easy solution aside from possibly rewiring the A/C circuit.
Not sure when your RV was made, but definately time to call the manufacturer and break out the wiring schematic in an attempt to isolate and resolve the problem.
Hope you find this helpful and best regards!
