Hi Jim,
It sounds like they are talking about the high voltage line as being disconnected.
At the unit the 220 line connects to the line side of the contactor.
Can you verify that you have a 220 line out there ?
Typically you will see a disconnect box located outside on the wall near the unit. The wires from indoors ( breaker panel ) run there first and can be fused or non fused but it should have a pull out disconnect.
The only real way to do this is to verify that the 220 line is ran from the breaker panel all the way through the disconnect and on to the contactor poles in the unit.
Would it be possible to post any photos of the situation ?
If so, I can probably be of more help to find where the break in the circuit.
Thanks
Mark
Thanks Mark:
A 5' section of power line has been removed (threaded connector at one end). I should have noticed this first but then I wouldn't need you (ha-ha). In your opinion, should I call and a/c tech or an electrician.
Hi,
If that was right at the unit they call that the "whip",
This is not hard to do if you are somewhat handy but if you aren't comfortable with electrical work I would call someone to do it. It sounds like it was disconnected in order for some other work to be done around the house maybe. That is the usual reason for a disconnection of that line. Its usually drain work being done or some kind of dig.
Basically it needs to reconnect and the two colored wire swill go the contcator line side terminals and the green wire goes to the ground lug. You should have at a minimum a voltage meter to attempt this.
