- Inspect the disconnect box: The disconnect box, usually located near the outdoor unit, houses a switch that isolates the unit from the power supply. Make sure the switch is in the "on" position.
- Test the outlet (if applicable): Some window AC units plug into an outlet. Use a different appliance to test the outlet to ensure it’s providing power.
- Examine the wiring: Look for any loose or damaged wiring at the circuit breaker, disconnect box, and the AC unit itself. However, if you are not comfortable working with electrical components, it’s best to call a qualified HVAC technician.

- Troubleshooting:
- Check the batteries: Replace the batteries in your thermostat, as low batteries are a frequent cause of thermostat malfunctions.
- Verify the settings: Make sure the thermostat is set to "cool" mode and that the temperature is set lower than the current room temperature.
- Check the wiring: If you’re comfortable, you can carefully check the thermostat wiring for loose connections. However, it’s often best to leave this to a professional.
