No, I doubt its a problem with the plug. I don't want to direct you into the wiring so lets try this . Rotate the thermostat control or if buttons alternately press the on and off buttons several times. If its a dial turn turn it several times then stop at lowest temp setting. Do the same to all the controls. This helps to clean the contacts on the controls. I don't know of any air conditioner that has a reset or breaker incorporated in its electrical.Takthere is any humming. The Fan should at least turn. If not, then someone will need to check to see where the power ends. Try the control cleaning a few times. Let me know if you will please. One more thing, Pull on the power cord and see if it is securely held in place, if not, Look closely where it passes through the cabinet to detect if the cord was pulled on. then check for any signs of kinking or crimping. The power cord itself may have been damaged somehow. Make sure all the prongs are tight . It has happened wher the cord on a unit being carried got caught on something and having hands full, It was jerked on to free it. Can't rule that out.. Good luck and stay in touch.
