Jack & Janet, and Mike,
I stand corrected. We have owned ]3] Hi Lo's and everyone of them had to be plugged in at the rear. I was unaware that there are some that are hard-wired.
That being the case, DaKaZ should thoroughly check his AC Circuit Panel. If he/she is unfamiliar with the way circuit breakers reset, I would suggest they find the AC circuit that is designated AC or Air Conditioner; if the circuit has blown, they must reset it. This is accomplished by moving the circuit breaker switch one way or the other [depending on if it is located on the left or right side of the panel], then move it in the opposite direction to reset it. It will have a clicking sound like cocking a pistol once it has been reset.
Good luck.
