To Next PageTo Next PageWhy does my Panasonic CU-E12NKUA show F91 (Refrigeration Cycle Abnormality)?
The F91 error code on your Panasonic Air Conditioner indicates a refrigeration cycle abnormality. This could be due to a refrigerant shortage (refrigerant leakage), poor compressor performance, a closed 2/3 way valve, or a detection error from faulty indoor intake air or indoor pipe temperature sensors.
How to improve heating/cooling efficiency of my Panasonic Air Conditioner?
To improve heating/cooling efficiency of your Panasonic Air Conditioner, ensure the temperature is set correctly, all doors and windows are closed, filters are clean or replaced, air inlet and outlet vents are unobstructed, the unit is not installed at an incline, and the front panel is properly closed.
Why does the power indicator blink before the Panasonic Air Conditioner is switched on?
The POWER indicator on your Panasonic Air Conditioner blinks before the unit is switched on as a preliminary step in preparation for operation when the ON timer has been set.
Why does the indoor fan stop occasionally during heating operation in my Panasonic CU-E12NKUA?
The indoor fan in your Panasonic Air Conditioner stops occasionally during heating operation to prevent unintended cooling effect.
Why does airflow continue after operation stops on my Panasonic CU-E12NKUA Air Conditioner?
The airflow in your Panasonic Air Conditioner continues even after operation has stopped to extract any remaining heat from the indoor unit; this process takes a maximum of 30 seconds.
What causes the F98 (Input Over Current Detection) error on a Panasonic CU-E12NKUA?
The F98 error on your Panasonic Air Conditioner indicates an input over current detection. This can be caused by over-current due to compressor failure, a defective outdoor unit PCB, a defective inverter main circuit electrolytic capacitor, or excessive refrigerant.
What causes the F90 (Power Factor Correction Protection) error in my Panasonic CU-E12NKUA Air Conditioner?
The F90 error code on your Panasonic Air Conditioner indicates power factor correction protection. This can be triggered by a DC voltage peak due to a power supply surge, a DC voltage peak due to non-uniform compressor windings, or a faulty outdoor PCB.
What does H16 (Outdoor Current Transformer Open Circuit) mean on my Panasonic CU-E12NKUA?
The H16 error code on your Panasonic Air Conditioner indicates an open circuit in the outdoor current transformer. This can be caused by a defective CT, a defective outdoor PCB, or a defective compressor (low compression).
What does it mean if my Panasonic CU-E12NKUA Air Conditioner displays F99 (Output Over Current Detection)?
If your Panasonic Air Conditioner shows error code F99, it indicates an output over current detection. This can be caused by a DC peak due to compressor failure, a defective power transistor, or a defective outdoor unit PCB. Checking the power transistor is suggested.
Why does my room have a peculiar odor when using my Panasonic CU-E12NKUA?
The peculiar odor from your room while using the Panasonic Air Conditioner may be due to damp smells emitted by the wall, carpet, furniture, or clothing.
