Question about Carrier 38CKC042 Air Conditioner
The contactor needs 2 power sources. 22ov sitting there waiting, and then 24v to close it. The 24v is referred tcoil wires. The 24 comes from the thermostat to the air handler inside, then leapfrogs outdoors to the condenser. Once in thecondenser it can run through low pressure switch also. The goal is to see where the 24v stops. Remove the 2strand wire from the unit (NOT the 220v) and see if 24v there. If not go back towards furnace...if it is there move on into the unit....if 24v is at contactor coil and it is not closed, then the contactor itself is bad.
