Problem
● During Heating operation, water may be produced from the out-
door unit due to the Automatic Defrosting operation.
● The room temperature sensor may be malfunctioning. Please
consult authorized service personnel.
Items to check
● Has there been a power failure
● 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
computers inside the room, or are there too many people in the
room?
If the problem persists after performing these checks, or if you notice burning smells, stop operation immediately, turn off the
electrical breaker, and consult with authorized service personnel.
