Upon arrival found system refrigerant levels low on 410A. No signs of leak at condenser unit. Once I got into attic I noticed both primary and secondary drain pans full with condensation causing safety device to stop system operation reason for service call. I Blew out and shop vac both drain pans. Then Checked for leak at evap coil, leak detector, detector went off at fins along bottom of evap coil.
