Why is my Fujitsu AOT24RZ Air Conditioner making noise?
Your Fujitsu Air Conditioner may produce noise due to a few reasons: - You might hear the sound of water flowing in the air conditioner’s piping during and immediately after operation. - The sound of coolant flowing may be noticeable for about 2 to 3 minutes after starting operation. - During heating, a sizzling sound may occur occasionally due to automatic defrosting.
Why is my Fujitsu AOT24RZ Air Conditioner not cooling well?
Several factors can affect the cooling performance of your Fujitsu Air Conditioner. Check if the air filter is dirty or if the air intake or outlet is blocked. Also, ensure the thermostat is set correctly. Other factors include open windows or doors, direct sunlight entering the room (for cooling), or the presence of heat-generating equipment or too many people in the room during cooling operation.
What to do if my Fujitsu Air Conditioner doesn't operate at all?
If your Fujitsu Air Conditioner isn't operating, first check if the power supply plug is properly connected to the outlet. Also, verify if there has been a power failure. Check the fuse to see if it has blown or if a circuit breaker has been tripped. Lastly, make sure the timer is not in operation.
How to improve cooling performance of Fujitsu AOT24RZ?
To enhance the cooling or heating performance of your Fujitsu Air Conditioner, start by cleaning or replacing the air filter. Ensure that the air intake grille and outlet port are free from obstructions. Verify that the thermostat is set correctly. Close any open windows or doors, and if sunlight is entering the room, close the curtains. Reduce heat sources and the number of people in the room.
Why does my Fujitsu AOT24RZ Air Conditioner operate differently from the remote control unit's setting?

What to do if my Fujitsu AOT24RZ doesn't turn on?
What to do if my Fujitsu Air Conditioner doesn't turn on? First, check if the power supply plug is disconnected from its outlet. Then, verify if there has been a power failure. Also, check whether a fuse has blown out, or a circuit breaker has been tripped. Finally, ensure that the timer is not operating.
Why does my Fujitsu AOT24RZ Air Conditioner airflow become weak or stop?
There are several reasons for weak or absent airflow in your Fujitsu Air Conditioner: - 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 stops, and the indoor unit operates at a very low fan speed. Increase the thermostat setting to warm the room further. - During heating, the unit may temporarily stop for 7-15 minutes for automatic defrosting; the OPERATION indicator lamp will flash during this time. - The fan may operate at very low speed during dry operation or when the unit is monitoring the room's temperature. - In monitor AUTO operation, the fan operates at very low speed.
Why is water coming from the outdoor unit of my Fujitsu Air Conditioner?
Water production from the outdoor unit of your Fujitsu Air Conditioner during heating operation is due to the automatic defrosting operation. This is normal.
How to fix a Fujitsu AOT24RZ Air Conditioner that doesn’t operate immediately?
If the Fujitsu Air Conditioner is stopped and then immediately started again, the compressor will not operate for about 3 minutes to prevent fuse blowouts. Whenever the power supply plug is disconnected and then re-connected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.
Why is my Fujitsu AOT24RZ not cooling (or heating) properly?
Poor cooling or heating performance of your Fujitsu Air Conditioner can occur due to several reasons. Check if the air filter is dirty, or if the air conditioner's intake grille or outlet port is blocked. Make sure you've adjusted the room temperature settings (thermostat) correctly. An open window or door can also affect performance. During cooling, bright sunlight entering the room or the presence of heating apparatus, computers, or too many people can also impact cooling efficiency. Close curtains to block sunlight.
