If you're experiencing a Wired Remote Controller Communication Error with your Fujitsu Air Conditioner, check the voltage. If it's DC12V, the remote control has failed and should be replaced. If it's DC 0V, the Controller PCB has failed and should be replaced after rechecking the remote control.
What to do if my Fujitsu Air Conditioner has a drainage error?
If your Fujitsu Air Conditioner is experiencing drainage issues, start by inspecting the float switch for proper operation using a meter to check its on/off switching. If the float switch is defective, replace it. Also, examine the drain hose for any clogs and clear them if necessary. If these steps don't resolve the issue, consider replacing the controller PCB.
How to fix a Fujitsu ASU12RLS2 indoor unit fan motor error?
If you're encountering an indoor unit fan motor error with your Fujitsu Air Conditioner, check first the fan and bearing. If either is damaged, replace them. If the motor itself is faulty, replace the indoor unit fan motor. If these steps do not resolve the issue, replace the controller PCB.
What to do if my Fujitsu Air Conditioner shows an indoor room thermistor error?
If your Fujitsu Air Conditioner displays an indoor room thermistor error, begin by checking the connector to ensure it is securely attached and properly connected, and verify that the thermistor cable is not open. If the thermistor is either open or shorted, replace it and then reset the power.
How to troubleshoot an Indoor Unit Model Information Error on my Fujitsu ASU12RLS2?
If your Fujitsu Air Conditioner is showing an Indoor Unit Model Information Error, check for external causes such as noise and ensure the ground connection is properly connected. Also, inspect all connectors for looseness or incorrect wiring, and check the PCB for any shorts or corrosion. If the problem persists, consider replacing the Controller PCB.
What does an Indoor Unit Capacity Error mean on my Fujitsu Air Conditioner?
If your Fujitsu Air Conditioner is showing an Indoor Unit Capacity Error, first verify the total capacity of the connected indoor units. If an abnormal condition is found, correct it by referring to the Installation Manual or Design & Technical Manual. If the problem persists, replace the Main PCB of the Outdoor unit.
How to fix a Serial Communication Error (Serial Reverse Transfer Error) on a Fujitsu Air Conditioner?
If your Fujitsu Air Conditioner displays a Serial Communication Error (Serial Reverse Transfer Error), check all connection lines between the indoor and outdoor units for any looseness or disconnections, referring to the Installation Manual or Data & Technical Manual for correction. Also, check the voltage of the power supply, ensuring it appears at the outdoor unit terminal L1 - L2 within the range of AC187V - 253V. Check that the indicated value swings between AC90V and AC270V at outdoor unit terminal 1 - 3. If the outdoor fan motor, active filter module, or IPM is abnormal, replace the corresponding part. If all parts are normal, replace the Main PCB.
How to resolve a Damper (Open/Close) simultaneous detection Limit switch error on a Fujitsu ASU12RLS2?
If your Fujitsu Air Conditioner displays a Damper(Open/Close) simultaneous detection Limit switch error, replace the limit switch if it is defective. If the problem persists, replace the Controller PCB.
