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

My furnace has a seperate breaker, and on the furnace is the
'controler'. Since I have a heatpump/AC unit, I would guess in your
situation, the controler is activating solenoids and relays, and
that's what is humming.

Get a professional, you might find someone to help real cheap by
networking. Check with your church members, coworkers, etc.

Good luck,
