When your Panasonic air conditioner starts acting up, the first thing you should do is check if it’s displaying any error codes on its screen. These codes are a direct way for the unit to communicate what kind of issue it’s encountering. However, understanding what each code means can be a challenge if you’re not familiar with them.
At codigodeerror.com, we want to make your life easier. That’s why we’ve put together a comprehensive table of the most common error codes that might appear on your Panasonic air conditioner, along with a description of each issue, its likely cause, and suggested solutions. Before we dive into the table, let’s clarify some concepts that might be useful for you.
Error codes: These are specific sequences of numbers and/or letters that the air conditioner displays when it detects an internal problem. Each code is associated with a specific type of failure.
Compressor: This is the heart of the air conditioning system, responsible for moving the refrigerant through the system to cool or heat your space.
Temperature sensor: Devices that detect the temperature of the air or certain parts of the air conditioner and send this information to the control unit.
Printed circuit: Boards that contain the electrical pathways and components that allow the air conditioner to operate.
With these concepts in mind, let’s look at the error code table:
| Error | Description | Cause | Solution |
|---|---|---|---|
| F11 | Failure in the cold/heat cycle change | – 4-way valve – Coil of the 4-way valve | |
| F90 | Failure of the Power Factor Correction (PFC) circuit | – Voltage of the Power Factor Correction (PFC) circuit | |
| F91 | Failure in the refrigeration circuit | – Poor refrigerant circulation (Valve closed, obstruction) | |
| F93 | Abnormal rotation of the compressor | – Compressor – Printed circuit of the outdoor unit | |
| F95 | High pressure protection in the outdoor unit (cooling) | – Dirty outdoor unit – Air recirculation ud. Exterior | |
| F96 | Overheating protection of the transistor module | – Excess refrigerant – Poor heat dissipation – Power transistor module. | |
| F97 | Overheating protection of the compressor | – Lack of refrigerant – Compressor | |
| F98 | Total consumption protection | – Excess refrigerant – Poor temperature dissipation | |
| F99 | CC peak intensity protection in the outdoor unit | – Printed circuit of the outdoor unit – Power transistor module – Compressor | |
| H11 | Communication error between units | – Interconnection cable – Printed circuit interior/exterior | |
| H14 | Failure of the indoor air temperature sensor | – Defective or disconnected air temperature sensor | |
| H15 | Failure of the compressor temperature sensor | – Defective or disconnected compressor temperature sensor | |
| H16 | Consumption detector (C.T.) of the outdoor unit in open circuit | – Exterior printed circuit – Power transistor module | |
| H19 | Indoor fan blocked | – Interior printed circuit – Fan motor | |
| H23 | Failure of the indoor heat exchanger temperature sensor | – Defective or disconnected temperature sensor | |
| H26 | Ionizer failure | – Ionizer connection in open circuit or short circuit | |
| H27 | Failure of the outdoor air temperature sensor | – Defective or disconnected air temperature sensor | |
| H28 | Failure of the outdoor heat exchanger temperature sensor | – Defective or disconnected temperature sensor | |
| H33 | Interior/Exterior connection error | – Interior/Exterior power supply voltage | |
| H98 | High pressure protection in the indoor unit (heating) | – Dirty air filter – Air recirculation ud. interior | |
| H99 | Anti-freezing protection in the indoor unit | – Lack of refrigerant – Dirty air filter |
Our advice
Before attempting any repairs on your own, it’s crucial to carefully read the description and suggested solution for the error code you’re facing. Some solutions might be simple and safe to perform by yourself, like cleaning a dirty air filter. However, others may require the intervention of a specialized technician, especially if they involve electrical components or the refrigerant system. Remember, safety first.
