Arrived onsite for no AC service call. Had customer turn on thermostat yo cool. Inside air handler began blowing. Went outside and the condenser did not come on. Performed diagnostic. Measured signal to the Contactor but no measurement in the common side. Checked and confirmed low and high pressure switches are closed and passing voltage. Checked air handler and confirmed cooling signal to condenser. Confirmed signal from condenser board to Contactor but no common signal back to the board. Confirmed fault in voltage distribution system. Also measure low 410a coolant. Homeowner elected bandaid repair.
