Common Panasonic Aircon Unit Error Codes

Just like any other aircon unit brand, the aircon issues of Panasonic aircon units running into performance issues is no longer a surprise. For the most part, these aircon issues are likely to go away after doing a couple of quick troubleshooting steps. There’s turning the unit on and off, unplugging it from the socket, or just simply letting it rest for an hour or two.

But for aircon issues that are hard to figure out, you will have to check the error code to help you zero in on a specific cause and repair. Each error code has a meaning, which will allow users to understand what the aircon issue is and thereby what needs to be done to fix it.

What are error codes?

All aircon unit systems come pre-programmed with a list of error codes that display on the control panel when the unit is running a fault.


The typical error codes can display for a variety of reasons including communication faults between the outdoor and indoor units (usually due to burnt out or faulty PCB), blocked filters, or low refrigeration gas charge.

1) Using the remote control, press and hold the check button for 5 seconds

2) Press and hold the timer button

3) Press the screen button to display the error code and power indicator light

4) Once the power and aircon lights start beeping, the error code will start to appear on the display

5) To turn off the error code query mode, simply hold down the check button for 5 seconds


Panasonic Aircon Error Codes: The Complete List



What should I do when an error code pops up?


There are two main things you can do when you see the error code:

1) Reset the aircon unit to check that the error message itself is not an error. Try this only if you are confident in electrical equipment around the home. This process will delete the aircon unit on board memory, giving it a restart.


Certain faults can be caused by the weather, lightning strikes, blackouts, and brownouts, or power fluctuations. These may be the reason for your aircon unit shutting down for safety reasons.


While not always successful, it’s worth a try rather than spending money on a professional aircon servicing company


How to do it: Separate your aircon unit from its power supply. Unplug it from a powerpoint, turn off the isolator next to the outdoor unit, or shut down your house’s power from the electrical board.

Leave for 15 – 30 minutes.


During this time the onboard memory will be deleted. Turn the power back on and restart your aircon unit. If the fault requires a professional aircon servicing company’s attention, then the error code will reappear.


If troubleshooting does not work, it is recommended to get a professional aircon servicing company in to have a look. It’s safer plus you don’t want to cause any further damage to your aircon unit, leaving you with a hefty repair bill.


They will not only recommend someone to assist you, but they can also conveniently lock in an appointment with every type of aircon servicing that you need.
