Hi,
I went out into the yard this evening and heard my air conditioner humming. The unit hasnt worked properly since we had a major power outage and so the only way to turn it on or off is at the breaker. I removed the wires going into the breaker but the unit is still humming. I openned the unit and the only power wires I can see are the black/white/ground. It is a very old sears model and I cant find any other shut off switch. What's going on!! Should I be concerned about the humming and if so, how can I completely remove the power to the unit without getting an electrician involved. I even tried going breaker by breaker to see if there was a wire touching but nothing stopped the humming
Thanks
