• A sound like a “GURGLE” can sometimes be heard during operation or when the unit stops.
- It is the sound of the refrigerant flowing through the unit.
• Bad smells can come from the unit.
- Smells such as smoke or cosmetics can accumulate while room air circulates through the unit.
- Cleaning the filters will reduce this problem.
• The outdoor fan does not rotate during heating operation.
- The unit is in defrost mode.
• UNIT ON lamp on the indoor unit display flashes and no air comes from the unit.
- It indicates malfunction of the unit and the compressor will stop operating.
