Panasonic Air Conditioner F97 error code

Difficulty: Hard · Cost: $200–$600 · Duration: Requires professional service

The F97 error means your Panasonic air conditioner's compressor overheating protection has activated — the compressor temperature has exceeded the safe operating limit. The compressor is the most critical and expensive component in the system. When it overheats the unit shuts down immediately to prevent permanent damage. This can be caused by insufficient refrigerant, poor ventilation, or a compressor fault. A qualified technician must inspect and resolve the issue before the unit is used again.

Common causes

Refrigerant is undercharged causing the compressor to work harder and overheat
Outdoor unit is in a poorly ventilated location causing heat buildup
Outdoor fan is not operating allowing heat to accumulate around the compressor
Compressor mechanical fault generating excessive heat

How to fix it

1

Turn off the unit at the circuit breaker immediately
2

Do not attempt to use the unit — compressor overheating can cause permanent damage
3

Contact a qualified technician to inspect the refrigerant charge, outdoor ventilation, and compressor condition
