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
