Has a fuse blown out, or a circuit breaker been tripped?
Is the timer operating?
Is the air filter dirty?
Are the air conditioner’s intake grille or outlet port blocked?
Did you adjust the room temperature settings (thermostat) cor-
rectly?
Is there a window or door open?
In the case of Cooling operation, is a window allowing bright sun-
light to enter? (Close the curtains.)
In the case of Cooling operation, are there heating apparatus and
