What does serial reverse transfer error during the operation mean for Fujitsu ASYA09LCC Air Conditioner?
If your Fujitsu Air Conditioner displays a serial reverse transfer error during operation, it means the indoor unit isn't receiving a signal for 10 seconds. Check the indoor/outdoor cable connection. If the wiring is normal, measure the voltage of the outdoor unit terminals and diagnose the defective location.
Why Fujitsu Air Conditioner has power supply frequency detection error?
If your Fujitsu Air Conditioner displays a power supply frequency detection error, it means the power supply frequency cannot be recognized after 4 seconds of power ON. The Controller PCB might be defective.
What does forced auto switch error mean on Fujitsu ASYA09LCC?
If your Fujitsu Air Conditioner displays a forced auto switch error, it means the forced auto switch has been ON for 30 consecutive seconds. Check if the forced auto switch is kept pressed. The forced auto switch might be defective or the Controller PCB might be defective.
What to do if my Fujitsu ASYA09LCC Air Conditioner shows outdoor temperature thermistor error?
If your Fujitsu Air Conditioner displays an outdoor temperature thermistor error, it means the detection value of the outdoor temperature thermistor is either open or shorted. Check the thermistor resistance value. The controller PCB might be defective.
What to do if my Fujitsu ASYA09LCC shows discharge thermistor error?
If your Fujitsu Air Conditioner displays a discharge thermistor error, it means the detection value of the discharge thermistor is either open or shorted. Check the thermistor resistance value. The controller PCB might be defective.
What does outdoor heat exchanger thermistor error mean for Fujitsu ASYA09LCC Air Conditioner?
If your Fujitsu Air Conditioner displays an outdoor heat exchanger thermistor error, it means the detection value of the outdoor heat exchanger thermistor is either open or shorted. Check the thermistor resistance value. The controller PCB might be defective.
What causes Indoor heat exchanger thermistor error in Fujitsu ASYA09LCC?
If your Fujitsu Air Conditioner shows an indoor heat exchanger thermistor error, it means the detection value of the indoor heat exchanger thermistor is either open or shorted when the power is ON. Check the thermistor resistance value. The controller PCB might be defective.
What does serial forward transfer error during the operation mean for Fujitsu ASYA09LCC Air Conditioner?
If your Fujitsu Air Conditioner displays a serial forward transfer error during operation, it means the outdoor unit isn't receiving a signal for 10 seconds. Check the indoor/outdoor cable connection. If the wiring is normal, measure the voltage of the outdoor unit terminals and diagnose the defective location.
Why Fujitsu ASYA09LCC Air Conditioner shows serial forward transfer error at starting up operation?
If your Fujitsu Air Conditioner displays a serial forward transfer error at startup, it means the outdoor unit isn't receiving a signal for 10 seconds after the power relay turns on. Check the indoor/outdoor cable connection. If the wiring is normal, measure the voltage of the outdoor unit terminals and diagnose the defective location.
Why my Fujitsu Air Conditioner does not operate at all?
If your Fujitsu Air Conditioner isn't operating, and the Operation Lamp and Timer Lamp aren't lit, you should check a few things: * Ensure the input power voltage from the exclusive circuit AC outlet is normal. * Make sure the AC plug is securely inserted into the AC outlet and isn't loose. * Verify that any connected cables are wired correctly. * Confirm that each connector is securely inserted.
