What to do if my Fujitsu ART doesn't operate at all?
If your Fujitsu Air Conditioner doesn’t operate, check if the circuit breaker has been turned off or if there has been a power failure. Also, verify whether a fuse has blown out, or a circuit breaker has been tripped. Finally, ensure that the timer is not operating.
Why is the airflow weak or stopping on my Fujitsu ART Air Conditioner?
There are several reasons why the airflow from 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 exceeds the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at a very low fan speed. The unit may also temporarily stop during heating for automatic defrosting (4-15 minutes). The fan may operate at very low speed during dry operation or when monitoring the room's temperature. If it is a multi-type unit, operation may stop if multiple units are operating in different modes. During QUIET operation or monitor AUTO operation, the fan will operate at a very low speed.
Why is there noise coming from my Fujitsu ART Air Conditioner?
During operation, you may hear the sound of water flowing in the Fujitsu Air Conditioner's piping, especially right after starting or stopping the unit. Also, noise may be noticeable for 2-3 minutes after starting due to coolant flow. During heating, a sizzling sound might occur occasionally due to automatic defrosting.
Why is air flow stopped in my Fujitsu ART?
There are several reasons why the air flow might stop in your Fujitsu Air Conditioner: * When Heating operation starts, the fan will not operate or it will operate at a very low speed to allow the internal parts to warm up. * During Heating operation, if the room temperature rises above the thermostat setting, the indoor and the outdoor unit will stop. To continue warming the room, set the thermostat to a higher setting. * During Heating operation, the unit will temporarily stop operation (between 2 and 16 minutes) as the Automatic Defrosting mode operates. * The fan may stop or operate at a very low speed when the unit is monitoring the room’s temperature.
Why does my Fujitsu ART smell?
A smell might be emitted from your Fujitsu Air Conditioner's indoor unit because room odors (from furniture, tobacco, etc.) have been drawn into the system.
