Why Fujitsu AOYR07LCC Air Conditioner shows serial reverse transfer error at starting up operation?
If your Fujitsu Air Conditioner displays a serial reverse transfer error at startup, it means the indoor 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.
What does main relay error mean on Fujitsu AOYR07LCC?
If your Fujitsu Air Conditioner displays a main relay error, it means that after 2 minutes 20 seconds of stopping operation, the signal from the outdoor unit is received even though the main relay is OFF. The main relay might be defective or the Controller PCB might be defective.
What causes a room temperature thermistor defective in Fujitsu AOYR07LCC?
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.
What to do if my Fujitsu 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 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 causes IPM protection in my Fujitsu AOYR07LCC 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 AOYR07LCC 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.
