OP - You say you "pulled out and plugged in my power cord." Does that mean this is one of the RV's where the genset powers an outlet that you plug your campground hookup cable into? Basically your genset creates a portable power pedestal?
Or, do you have an Automatic Transfer Switch/ATS as described by WyoTraveler above? Much simpler to troubleshoot with the outlet vs. the ATS.
My '94 Minnie Winnie has an Automatic Transfer Switch. I had this problem once before. I had a guy fix it. When I asked him what he did he said he replaced a part under the dinette seat. When I asked more, he was VERY vague. I don't think he did what he said he did. When he drove it back to me the generator was running and the A/C was blowing cold. The next day cranked up the generator, then turned on the A/C.
A week later (last weekend) we went camping. We got to the camp site and plugged into a 30 amp plug. We ran the A/C that evening.
Now, another week later, I start up the generator, then turn on the A/C. It doesn't come on. I turned off the generator, pulled out the power cord and plugged into a 30 amp outlet at my house. The A/C came on.
