Why is water produced from the outdoor unit of my Fujitsu ART Air Conditioner?
During Heating operation, water may be produced from the outdoor unit of your Fujitsu Air Conditioner due to the Automatic Defrosting operation.
Why is my Fujitsu Air Conditioner cooling or heating poorly?
Several factors can cause poor cooling or heating performance in your Fujitsu Air Conditioner. Check if the air filter is dirty, or if the air conditioner’s intake grille or outlet port is blocked. Make sure the room temperature settings (thermostat) are correctly adjusted and that no windows or doors are open. For cooling, check if sunlight is entering the room (close the curtains) or if there are heat-generating appliances or too many people in the room. Finally, verify that the unit is not set to QUIET operation.

How to improve cooling performance of my Fujitsu ART?
If your Fujitsu Air Conditioner isn't cooling effectively, there are several potential causes and solutions: * Ensure the air filter is clean; if it's dirty, clean or replace it. * Make sure the air conditioner's intake grille and outlet port are free from obstructions. * Verify that the thermostat settings are correctly adjusted. * Close any open windows or doors. * Close curtains to block bright sunlight. * Reduce heat sources and the number of people in the room. * Check if the unit is set to QUIET operation; if so, change the operation mode if better performance is needed.
What to do if my Fujitsu Air Conditioner doesn’t operate at all?
If your Fujitsu Air Conditioner doesn't operate, verify that the circuit breaker hasn't been turned off, that there hasn't been a power failure, or that a fuse hasn't blown or the circuit breaker tripped. Also, check if the timer is operating.
Why does my Fujitsu ART Air Conditioner airflow is weak?
Weak airflow in your Fujitsu Air Conditioner can occur for several reasons: * When heating starts, the fan speed is temporarily low to warm internal parts. * The outdoor unit stops when the room temperature exceeds the thermostat setting; increase the thermostat setting. * The unit temporarily stops (4-15 minutes) for Automatic Defrosting during heating. * The fan operates at very low speed during Dry operation or while monitoring room temperature. * The fan operates at very low speed during QUIET operation. * The fan operates at very low speed during monitor AUTO operation.
Why is my Fujitsu Air Conditioner emitting mist or steam?
Mist or steam from your Fujitsu Air Conditioner can occur due to: * Sudden cooling of room air, leading to condensation during Cooling or Dry operation. * Automatic Defrosting operation during Heating, which may cause the outdoor unit’s fan to stop and steam to rise.
Why does Fujitsu ART doesn’t operate immediately?
Your Fujitsu Air Conditioner might not start immediately due to: * A 3-minute delay for the compressor to prevent fuse blowouts. If stopped and restarted, wait 3 minutes. * A 3-minute protection circuit operation after turning the electrical breaker off and on.
What causes noise from my Fujitsu Air Conditioner?
Noises from your Fujitsu Air Conditioner can be due to: * The sound of water flowing in the air conditioner’s piping during operation, which is normal. * Noticeable noise for 2-3 minutes after starting, possibly coolant flowing. * A sizzling sound from Automatic Defrosting during Heating operation.
