Confirm the air conditioner is plugged in and there is power at the wall receptacle. If the wall receptacle is 120 volts, you can plug another small appliance into the receptacle to confirm there is power. For 220 volt units you will need to use a multimeter. If there is no power, confirm the circuit breaker has not tripped. Most air conditioners will have a separate breaker on the power cord plug. Confirm this breaker is not tripped. If the blower motor is working then the unit has power.
