Speedey, we have been living here for 11 months the house is fairly new and the wiring is all new and I do agree, I should't be doing this myself but I am here to learn not hurt myself. Yoyizit, I have nothing else on that outlet except the A/C and I don't have a meter. How can I tell if it is the unit itself. The first two weeks I had it, everything was running fine.
Without a meter I guess you could plug in a load equivalent to that of the AC in the AC outlet and see if the symptom repeats. Each 100w incand. bulb = 0.83 A. What's written on the nameplate for the AC? It might only pull 4A or so.
You could also Google your make and model along with the exact phrase
I assume you mean your panel breaker and not the button on the huge fat plug that ACs now have.
if it was a cheap a/c, you could be having comp problems already. seen it happen many times. myself included. had one last about a month.
i would check for loose connections from breaker to receptacle.
