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 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.
Why is water coming from the outdoor unit of my Fujitsu 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 ART Air Conditioner not cooling well?
If your Fujitsu Air Conditioner isn't cooling effectively, consider these possible causes: * Check if the air filter is dirty. * Ensure that the air conditioner's intake grille or outlet port are not blocked. * Verify that you've adjusted the room temperature settings (thermostat) correctly. * Make sure no windows or doors are open. * In Cooling operation, close the curtains if bright sunlight is entering the room. * In Cooling operation, consider whether there are heating apparatus and computers inside the room, or too many people.
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 doesn't my Fujitsu ART operate immediately?
Your Fujitsu Air Conditioner might not operate immediately because: * If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes to prevent fuse blowouts. * Whenever the electrical breaker is turned off then on again, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.
What to do if thermo sensor display on my Fujitsu Air Conditioner remote controller is flashing?
The room temperature sensor may be malfunctioning. Please consult authorized service personnel.
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.
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.
