Panasonic Air Conditioner Error Codes: Using the Self-Diagnosis Function

At Panasonic, we understand the importance of maintaining a comfortable living environment. That's why our air conditioners are built with reliability and efficiency in mind. But even the most dependable equipment can experience occasional issues. To ensure your continued comfort and minimize downtime, Panasonic air conditioners feature a built-in Self-Diagnosis Function.

What is Self-Diagnosis Function?
Self-Diagnosis Function is a valuable tool for identifying potential issues with inverter models of Panasonic air conditioners. In the event of a malfunction, the unit will automatically diagnose the problem and display a corresponding alphanumeric error code. This error code can be referenced in the user manual or provided to a service technician for quick and accurate troubleshooting. By pinpointing the issue efficiently, the Self-Diagnostic Function helps minimize repair time and ensures a smoother service experience.

What is Error Code?
An error code is a three-digit alphanumeric code displayed on the remote control or from the Panasonic Comfort Cloud App. This code indicates a potential malfunction within your Panasonic air conditioner. You can refer Error Code Table below for a basic explanation or provide it to a qualified service technician for quick and accurate troubleshooting.
