      If your McQuay Air Conditioner fails to start, make sure the voltage is within +/- 10% of the rated voltage. Check for any interruptions in the power supply and ensure the control settings are correct. Verify that the air conditioner is connected to the main power source and check if the fuse is blown or the circuit breaker is off.
