On the Temperature switch, The wire that got hot is 120 volts, I put the meter to this wire (RED WIRE) with the temp switch OFF there is 120 volts on the red wire, OK I turn the temp switch until it clicks, There should be 120 volts on both wires and there is not anything, No Power what so ever, What would cause this.
I don't think it's that there's no power on the switch. I think it's your method of trying to figure out if the switch is bad.
Disconnect the switch, take it out of the system entirely. Put the meter on continuity check or ohms check. With the switch off, should be wide open, maximum resistance. With the switch on, should be continuity (beeping or whatever on the meter), or really close to zero ohms. Make sure to take a read of the meter leads resistance and subtract that from the reading of the switch itself.
If the switch and wires got hot once, the contacts inside the switch are probably burned up or bent/warped a bit.
And if that end of the wires got hot, I'd imagine the other end of the wires probably got hot too, ya know, buried deep within the A/C unit itself where it's almost impossible to reach :) Might have rotten connections at BOTH ends of the thermostat wires.
I wish I was down there. We'd have this problem licked in no time flat...if not sooner...
