    Troubleshooting Steps

    1. Check the Power Supply: Ensure the air conditioner is plugged in and the circuit breaker hasn’t tripped.
    2. Inspect the Start Capacitor: If the AC hums but doesn’t start, the start capacitor may be faulty. Replace it if needed.
    3. Test the Compressor Relay: A faulty relay can prevent the compressor from starting. Replace it if necessary.
    4. Listen for Sounds: If you hear clicking or buzzing, the compressor or relay may be failing.
    5. Check Refrigerant Levels: Low refrigerant can cause the compressor to overheat and shut off. Call a technician to recharge the refrigerant.
