Roof AC Quit

[Gus]

Hello everyone. Thank you all for your input on the
microwave issue. I decided to replace it with a Sharp R-1874 convection
oven and will install it when it arrives. It was $449.00 including
shipping.

My next problem is the forward roof AC. It has quit working.
I have done the following:

1)
Checked the thermostat by putting it on another unit
and it worked fine

2)
Checked the switch on the dash and it worked also

3)
Checked to make sure I was getting 110 volts at the
unit, which I was

4)
The unit quit while it was running

5)
I took the interior plastic covers off and discovered a
connection that looks like a computer cable that has green corrosion on
it. I think this is probably the culprit but not sure. Is this
cable the one that connects to the thermostat? Where can I find a
replacement cable and is it difficult to get it through the roof to the
thermostat? It looks like it could get hung up somewhere.

Any input is appreciated. Any guidance as to the
repair of replacement of unit is also appreciated.
