Common Panasonic Air Conditioner Fault Codes (Split & Ducted Systems)

Common Panasonic Air Conditioner Fault Codes – Wall Split & Reverse-Cycle Ducted Systems

When your Panasonic air conditioner stops working as it should, it often displays a fault code to indicate what’s gone wrong. Knowing how to interpret these codes can help you understand whether it’s a minor issue or time to call a professional Canberra local technician.

In this guide, the team at Air Turners has outlined the most common Panasonic fault codes for both wall-mounted split systems and reverse-cycle ducted systems used throughout Canberra and Queanbeyan.

⚠️ Important: While these codes are helpful for initial diagnosis, most faults should only be handled by a licensed technician. Call (02) 6294 4443 or book a service online if you need professional support.


🌬️ Panasonic Wall Split System Fault Codes

These codes usually appear on the indoor unit display or can be extracted using a remote control diagnostic function (depending on the model).

Common Panasonic Wall Split Fault Codes

  • H11: Communication failure between indoor and outdoor units
  • H14: Indoor temperature sensor failure
  • H97: Outdoor fan motor fault
  • H98: High discharge temperature (possible gas shortage or airflow issue)
  • H99: Indoor coil freeze prevention activated
  • F11: Outdoor temperature sensor fault
  • F90: Compressor start-up failure
  • F93: Abnormal compressor speed detection (may indicate a seized or faulty compressor)

What Should You Do?

  1. Turn off the system at the isolator switch for 3–5 minutes
  2. Restart the unit and monitor for the recurrence of the fault
  3. If the code returns, book a technician to investigate further

Panasonic splits are efficient and reliable, but these error codes usually indicate an issue that requires licensed support, especially those involving sensors, fans, or refrigerant.


🏠 Panasonic Reverse-Cycle Ducted System Fault Codes

Panasonic ducted systems in Canberra homes commonly use a central controller (wired wall unit) to manage zones and display fault codes. These systems are reverse-cycle (cooling + heating) and rely on indoor and outdoor unit communication.

Common Ducted System Fault Codes

  • H11: Communication error between indoor and outdoor units
  • H16: Current overload (typically in the compressor circuit)
  • H19: Indoor fan motor fault
  • H62: Indoor heat exchanger sensor fault
  • F91: Low refrigerant or cooling capacity dropped
  • F93: Compressor speed mismatch
  • F94: Discharge pipe temperature is too high
  • H99: Indoor coil frosting issue

Zone System Issues

Some Panasonic ducted systems are integrated with aftermarket zone control systems (e.g. iZone, AirTouch, or MyAir). While these don’t show Panasonic codes, communication issues between the two systems can cause performance failures.

When to Call a Ducted System Specialist

If your Panasonic ducted unit is not heating or cooling correctly, or is displaying any of the above fault codes, it may indicate:

  • Fan motor or sensor failure
  • Low refrigerant or gas leak
  • Compressor protection mode activation
  • PCB (Printed Circuit Board) fault

These systems should only be inspected and serviced by licensed technicians. We’re fully ARCtick certified and experienced with Panasonic ducted diagnostics and repairs across the ACT and Queanbeyan region.
