Panasonic AC Error Code List
Air conditioners, especially smart ones like those from Panasonic, come with built-in diagnostics that make identifying issues much easier. These diagnostics show error codes on the unit or remote, signaling specific problems. However, if you don’t know what these codes mean, they can be pretty confusing. Don’t worry, though! In this guide, we’ll explain each error code in simple terms, provide the possible reasons for the error, and offer solutions that you can try.
What Are Panasonic AC Error Codes?
When your Panasonic AC detects something wrong, it triggers an error code on the display panel or remote control. These codes are designed to help technicians or users troubleshoot the issue without having to guess what’s wrong.
Some errors are minor and easy to fix, while others require professional intervention. Let’s dive into the most common codes, what they mean, and what you can do about them.
Common Panasonic AC Error Codes
Here’s a breakdown of the most frequent error codes, organized into categories for easier navigation.
Error Codes Related to Communication Problems
H11 – Communication Failure Between Indoor and Outdoor Units
- Reason: The indoor and outdoor units aren’t able to “talk” to each other. This is often due to faulty wiring or loose connections.
- Possible Causes:
- Damaged or disconnected communication wire
- Control board failure
- Solution:
- Check the wiring between the indoor and outdoor units.
- Tighten or replace any loose or damaged connectors.
- If the issue persists, consult a technician to inspect the control boards.
| Error Code | Description | Cause | Solution |
|---|---|---|---|
| H11 | Communication failure | Wiring issue | Check and secure connections |
| Control board failure | Replace faulty control boards |
Error Codes Related to Sensor Issues
H14 – Indoor Intake Air Temperature Sensor Malfunction
- Reason: The air intake sensor isn’t working properly.
- Possible Causes:
- Sensor is disconnected or damaged.
- Sensor circuit shorted or open.
- Solution:
- Inspect the air intake temperature sensor for continuity.
- If the sensor is defective, replace it.
| Error Code | Description | Possible Cause | Solution |
| H14 | Intake air sensor malfunction | Disconnected or shorted sensor | Inspect and replace sensor |
| Faulty wiring | Check and fix wiring |
H23 – Indoor Heat Exchanger Sensor Error
- Reason: The sensor monitoring the heat exchanger is faulty.
- Possible Causes:
- Sensor is damaged or disconnected.
- Internal wiring issues.
- Solution:
- Inspect the heat exchanger sensor for damage or disconnection.
- Replace the sensor if necessary.
Error Codes Related to Compressor Problems
H15 – Compressor Temperature Sensor Malfunction
- Reason: The sensor monitoring the compressor temperature is not functioning properly.
- Possible Causes:
- The sensor is disconnected, shorted, or damaged.
- Compressor overheating.
- Solution:
- Check the temperature sensor for proper connectivity.
- Ensure there’s no obstruction in the airflow.
- Replace the sensor if it’s defective.
| Error Code | Description | Cause | Solution |
| H15 | Compressor temperature sensor | Damaged or disconnected sensor | Check sensor connectivity |
| Overheating compressor | Ensure airflow is unobstructed |
Error Codes Related to Fan Motor and Airflow
H19 – Indoor Fan Motor Mechanism Locked
- Reason: The fan motor isn’t turning, possibly due to a mechanical blockage or electrical failure.
- Possible Causes:
- Jammed motor or foreign objects inside.
- Faulty motor circuit or control board.
- Solution:
- Turn off the AC and inspect the fan motor.
- Remove any debris obstructing the motor.
- Replace the fan motor if it’s faulty.
Critical Error Codes
F93 – Abnormal Compressor Revolution
- Reason: The compressor isn’t running at the correct speed.
- Possible Causes:
- Defective inverter board.
- Compressor motor issue.
- Solution:
- Check the inverter board for defects.
- Inspect the compressor motor and wiring.
- Replace faulty components if necessary.
| Error Code | Description | Possible Cause | Solution |
| F93 | Abnormal compressor revolution | Inverter board failure | Inspect and replace components |
| Damaged compressor motor | Check and repair motor |
High-Pressure and Overheating Protection Codes
H98 – Indoor High-Pressure Protection
- Reason: The system is detecting high pressure inside the indoor unit.
- Possible Causes:
- Blocked air filter or restricted airflow.
- Refrigerant overcharge.
- Solution:
- Clean or replace the air filter.
- Check refrigerant levels and adjust if needed.
F97 – Compressor Overheating Protection
- Reason: The compressor is overheating due to excessive load or lack of refrigerant.
- Possible Causes:
- Insufficient refrigerant.
- Defective compressor motor.
- Solution:
- Verify refrigerant levels and top up if required.
- Inspect the compressor motor for issues and replace if necessary.
Maintenance Tips to Prevent Error Codes
While some error codes are unavoidable, regular maintenance can significantly reduce the chances of encountering many of these problems.
Here are a few tips to keep your Panasonic AC in top shape:
- Clean or Replace Filters Regularly: Dirty filters restrict airflow, leading to overheating and high-pressure errors.
- Inspect Wiring and Connections: Loose or damaged connections are a common cause of communication errors.
- Check for Obstructions: Ensure that both indoor and outdoor units have adequate clearance and that fans are not obstructed.
- Monitor Refrigerant Levels: Low or excessive refrigerant levels can cause various issues, including overheating and abnormal compressor performance.
Quick Reference Table for Error Codes
| Error Code | Description | Possible Causes | Solution |
| H11 | Communication failure | Wiring issue | Check and secure connections |
| H14 | Intake air sensor malfunction | Sensor damage or disconnection | Inspect and replace sensor |
| H15 | Compressor temperature sensor error | Overheating or faulty sensor | Check airflow and sensor |
| H19 | Indoor fan motor lock | Jammed motor or faulty wiring | Remove debris, inspect motor |
| F93 | Abnormal compressor revolution | Inverter board failure | Check and replace components |
| H98 | High-pressure protection | Dirty filter or airflow block | Clean filter, ensure airflow |
| F97 | Compressor overheating | Low refrigerant or motor issue | Top up refrigerant, inspect motor |
When to Call a Technician
Some issues can be resolved by performing simple checks and maintenance tasks. However, if you encounter complex problems like compressor failure (F93) or inverter board defects, it’s best to call a certified HVAC technician. Attempting to fix these problems on your own can lead to further damage or void the warranty.
Conclusion
Panasonic AC error codes may seem intimidating at first, but with this guide, you now have a clear understanding of what each code means and how to resolve it. Regular maintenance, including cleaning filters and checking refrigerant levels, can help prevent many common issues. For major errors, don’t hesitate to contact a professional.
