· About 3 minutes delay is applied to protect compressor from frequenty
on/off.|
Does not cool or heat effectively.| · Is the air filter dirty? See air filter
cleaning instructions.| 23-25
· Has the temperature been set correctly?| 12, 15
· Are the indoor unit’s air inlet or outlet vents obstructed?|
The air conditioner operation is noisy.| · For a noise that sounds like water
flowing. -This is the sound of refrigerant flowing inside the air conditioner
unit.
· For a noise that sounds like the compressed air releasing into atmosphere.
-This is the sound of the dehumidifying water being processed inside the air conditioning unit.|
Remote Controller display is faint, or no display at all.| · Are the
batteries depleted?
· Are the batteries inserted in the opposite (+) and (-) directions?| 9
Crack sound is heard.| · This sound is generated by the
