OK. If it is getting power, all the other suggestions are moot. The air conditioner is broken.
RE: the converter question - my advice is based on the assumption you have a popup (this question is in the folding trailer sub-forum) but that doesn't appear to be the case. I'm not familiar with the wiring of a bigger rig, but the concept is the same. On a popup, the converter provides a space for the 110VAC breaker panel. From the breakers, the power is distributed to the camper AND routed to the INPUT of the converter. The converter takes the 110VAC and makes 12VDC. The 12VDC OUTPUT of the converter is protected by fuses.
So even though the breakers are physically located on the converter panel, they are not part of the converter's function (other than providing input power to the converter).
