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 to do if my Fujitsu ASYA09LCC Air Conditioner shows excessive high pressure protection on cooling?
If your Fujitsu Air Conditioner is showing an excessive high pressure protection error during cooling, check the following: * Ensure that heat radiation is not blocked at the inlet or outlet. * Verify that the outdoor fan is functioning correctly and rotating. * Check for any issues with the refrigeration cycle.
What causes IPM protection in my Fujitsu Air Conditioner?
If your Fujitsu Air Conditioner is showing IPM protection, it indicates that an abnormal current value has been detected. Here's what you should check: * Ensure that heat radiation is not blocked at the inlet or outlet. * Verify that the outdoor fan is functioning correctly and rotating. * The controller PCB might be defective.
What to do if my Fujitsu Air Conditioner has indoor fan lock error?
If your Fujitsu Air Conditioner displays an indoor fan lock error, it means the indoor fan speed is 0 rpm after 56 seconds from starting or changing the fan mode. Here’s what to check: * Check the fan motor connector for looseness or defective contact. * The fan motor might be defective. * The controller PCB might be defective.
What to do if my Fujitsu ASYA09LCC Air Conditioner has indoor fan speed error?
If your Fujitsu Air Conditioner displays an indoor fan speed error, it means the indoor fan speed is 1/3 of the target frequency after 56 seconds from starting or changing the fan mode. Here’s what to check: * Check the fan motor connector for looseness or defective contact. * The fan motor might be defective. * The controller PCB might be defective.
What causes a room temperature thermistor defective in Fujitsu ASYA09LCC Air Conditioner?
If your Fujitsu Air Conditioner shows a room temperature thermistor defect, it means the thermistor detected an abnormal temperature when the power was turned on. Check the thermistor resistance value. The controller PCB might be defective.
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 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 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.
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.
