Why is my Fujitsu Inverter Halcyon 9374379378 Air Conditioner making noise?
Your Fujitsu Air Conditioner may be making noise due to several reasons: * You might hear water flowing in the air conditioner’s piping during or immediately after operation. * You might hear the sound of coolant flowing, especially noticeable for about 2 to 3 minutes after starting operation. * During heating, a sizzling sound may occur due to the automatic defrosting operation.
Why is the airflow weak or stopping in my Fujitsu Inverter Halcyon 9374379378 Air Conditioner?
There are several reasons why the airflow in your Fujitsu Air Conditioner might be weak or stop: * When heating starts, the fan speed is temporarily very low to allow internal parts to warm up. * During heating, if the room temperature rises above the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at a very low fan speed. * During heating, the unit will temporarily stop operation (between 4 and 15 minutes) as the automatic defrosting mode operates. * The fan may operate at a very low speed during dry operation or when the unit is monitoring the room’s temperature. * During QUIET operation, the fan will operate at a very low speed. * In monitor AUTO operation, the fan will operate at a very low speed.
Why is my Fujitsu Inverter Halcyon 9374379378 emitting mist or steam?
The emission of mist or steam from your Fujitsu Air Conditioner can occur due to: * During cooling or dry operation, a thin mist may be seen because of the sudden cooling of room air, resulting in condensation. * During heating, the outdoor unit’s fan may stop, and steam may rise from the unit due to the automatic defrosting operation.
What to do if Fujitsu Inverter Halcyon 9374379378 doesn’t operate immediately?
