This is what Im getting at. Its really odd that if I have all the
wires out, it still hums. So Im wondering whether there would be a
separate power source for the fan on the unit that is giving power to
the thing. In fact, I had bees living underneath the unit this summer
and had them killed off. Last night when I went out to look at the
contactor, there were small worms crawling on the points - still alive,
so there wasnt much power going to them but I wonder if they have
shorted something.

Im off to get my palm read and maybe that'll help.

Thanks

Mano
