Panasonic air conditioners are hailed for their superior quality and durability for their price range, but your air conditioner may still encounter problems from time to time. Most of these problems can be solved by doing a couple of quick troubleshooting steps: turning the unit on and off, unplugging it from the socket, or just simply letting it rest for an hour or two.

The error code displayed on the remote control, indoor, or outdoor unit of your air conditioner indicates the problem with your unit. Always refer back to your owner's manual for troubleshooting steps, or check our Panasonic AC troubleshooting guide.
