Measured line voltage at the disconnect and equipment lugs to confirm stable power supply.
Tested the thermostat control circuit and low-voltage wiring for shorts, opens, or miswiring.
Evaluated contactor operation and coil voltage to ensure reliable system switching.
Checked the run capacitor values and wiring integrity for the compressor and fan circuits.
Assessed motor circuits (compressor and condenser fan) for continuity and abnormal resistance.
Inspected wiring terminations for looseness, corrosion, or arcing, and corrected as needed.
Documented findings and reviewed next-step options with the homeowner.
