What Does Error F98 Mean?

The Panasonic Air Conditioner error code F98 signifies a communication failure between the indoor and outdoor units, triggered by an over-current protection mechanism due to abnormally high current draw. This results in the unit ceasing operation and the error code flashing on the display, leading to a loss of cooling or heating functions. Addressing this issue promptly is crucial to restoring proper performance.

Common Symptoms:

  • Unit stops running when F98 appears
  • Timer or error LED flashing when F98 is displayed
  • Loss of cooling/heating function when protection triggers

Possible Causes

  • Abnormal high current draw detected (high)
  • Compressor failure or overload (medium)
  • Outdoor unit PCB/inverter or power module faults (medium)
  • Excessive refrigerant or refrigerant system issues increasing load (medium)

How to Fix Error F98

DIY Fix Basic checks and safe reset attempt

  1. Turn off the air conditioner and disconnect from power at the breaker or plug.
  2. Wait at least 3–5 minutes to allow internal circuits to discharge.
  3. Ensure outdoor unit is free of obstructions and debris for proper airflow.
  4. Restart the unit and observe if F98 reappears.

Technician Only Professional diagnosis and repair

  1. Measure operating current and compare against rated values using clamp meter.
  2. Inspect compressor load characteristics and evaluate potential compressor damage.
  3. Examine outdoor unit PCB, inverter power electronics, and current sensor circuits for faults.
  4. Check refrigerant charge level and circuit for blockages or abnormalities.
  5. Verify proper supply voltage and wiring integrity.

Parts needed: Clamp current meter for testing, Compressor motor and internal components, Outdoor unit PCB / inverter module, Current sensing components, Refrigerant pressure and charging tools

🛑 When to Call a Pro:
