Urgency

Likely causes

1. Compressor motor or bearings are failing or locked
2. Inverter drive is not controlling compressor speed correctly
3. Refrigerant pressure or airflow problem is overloading the compressor
4. Power-supply or outdoor control-board fault

Homeowner fix

Turn the system off and power cycle once if safe. Do not open the outdoor unit or attempt compressor or inverter work.

When to call a pro

Call an authorized Panasonic dealer if F 93 returns. Tell them Panasonic lists F 93 as outdoor compressor abnormal revolution.
