AC startup problem diagnosis
No-start repair sequence

- Verify thermostat settings, batteries, wiring, and cooling call.
- Confirm breaker, disconnect, fuse, float switch, and low-voltage power.
- Test contactor, capacitor, fan motor, transformer, control board, and compressor circuit.
- Check for water overflow, frozen coil conditions, locked rotor symptoms, or repeated trip history.
