Hello again, If the contractor is an Air conditioning contractor he should have no problem sorting out what the problem is. So far it sounds like the unit is not getting 230 volts, if the contactor is pulled in and the fan on the unit is not running, then the chances are in the 99% range that the disconnect switch is off or it is not wired properly or has a bad wire connection somewhere in the circuit... this should not be difficult for the HVAC contractor to locate and repair. Tell me in detail how it has gone with him so far.We can go from there.
