What causes the F99 (Output Over Current Detection) error in Panasonic CU-E12NKD?
The F99 error code indicates an Output Over Current Detection. This can be caused by a faulty outdoor unit PCB or a faulty compressor.
What does H99 error mean on my Panasonic CU-E12NKD Air Conditioner?
The H99 error code on your Panasonic Air Conditioner indicates an indoor freeze prevention protection during cooling or soft dry modes. This can be caused by several factors: an air short circuit at the indoor unit, a clogged air filter, dust accumulation on the heat exchanger, a closed 2/3 way valve, a faulty fan motor, refrigerant shortage (leakage), a clogged expansion valve or strainer, a faulty pipe temperature sensor, or a faulty indoor unit PCB.
What does error code F95 mean on a Panasonic CU-E12NKD Air Conditioner?
The F95 error code indicates a cooling high pressure abnormality. This could be due to an air short circuit at the indoor unit, dust accumulation on the indoor unit heat exchanger, a closed 2/3 way valve, a faulty outdoor unit fan motor, excessive refrigerant, a clogged expansion valve or strainer, a faulty outdoor pipe temperature sensor, or a faulty outdoor unit PCB.
Why does my Panasonic CU-E12NKD Air Conditioner show H12 (Indoor/Outdoor Capacity Rank Mismatched) error?
The H12 error code on your Panasonic Air Conditioner indicates a capacity rank mismatch between the indoor and outdoor units. This can occur due to wrong models being interconnected, incorrect indoor or outdoor unit PCBs being mounted, defective PCBs, or signal transmission errors caused by incorrect wiring or wire breakage.
What causes the F93 Compressor Rotation Failure in Panasonic CU-E12NKD Air Conditioner?
The F93 error code indicates a compressor rotation failure. This could be due to a disconnected compressor terminal, a faulty outdoor PCB, or a faulty compressor.
What does H32 error mean on my Panasonic Air Conditioner?
The H32 error code on your Panasonic Air Conditioner indicates an abnormality with the outdoor heat exchanger temperature sensor 2. This can be caused by a faulty connector connection, a faulty sensor, or a faulty PCB.
What does H28 error mean on my Panasonic CU-E12NKD?
The H28 error code on your Panasonic Air Conditioner indicates an abnormality with the outdoor pipe temperature sensor. This can be caused by a faulty connector connection, a faulty sensor, or a faulty PCB.
What does H27 error mean on my Panasonic CU-E12NKD Air Conditioner?
The H27 error code on your Panasonic Air Conditioner indicates an abnormality with the outdoor air temperature sensor. This can be caused by a faulty connector connection, a faulty sensor, or a faulty PCB.
What does F11 (4-way valve Abnormality) mean for Panasonic Air Conditioner?
The F11 error code indicates a 4-way valve abnormality. This can be caused by a connector in poor contact, a faulty sensor, a faulty outdoor unit PCB, or a defective 4-way valve.
What causes the F97 (Compressor Overheating) error in Panasonic CU-E12NKD?
The F97 error code indicates compressor overheating. This can be caused by a faulty compressor tank temperature sensor, a closed 2/3 way valve, refrigerant shortage (refrigerant leakage), a faulty outdoor unit PCB, or a faulty compressor.
