Starting to sound like either a loose wire, or a dead compressor motor. I have plugged in my Seneca to the house on a 15 amp circuit with adapters from my 50 amp to a regular 50 foot extension cord (12 gauge, I think). The AC will start, and the compressor will run, but when I measure the voltage at other 115vac outlets in the coach, it reads 98 volts. That is MUCH too low, and I won't run it that way. When the voltage drops, the motor begins to draw more current. Too low, and the current goes higher than the motor can handle, and it overheats. That destroys motors very quickly. It is possible the power pole from which you disconnected was running your compressor at a very low voltage, and killed the motor. It is also possible you have a bad connection, bad fuse, or circuit breaker tripped. I doubt the fan and the compressor would be on two separate breakers, but it's possible I suppose. Try those first, and if you find nothing odd, I would have a tech look into it and troubleshoot. Could even be a bad thermostat. That would be a lucky break.
