Panasonic F 98 error code

What it means

Panasonic lists F 98 as total running current protection. The unit has detected a current-protection condition.

Urgency

Likely causes

1. Outdoor unit is overloading from restricted airflow or a dirty coil
2. Compressor, fan motor, or inverter is drawing abnormal current
3. Low/high supply voltage or an electrical supply problem
4. Outdoor control board or current sensor fault

Homeowner fix

Turn the system off and power cycle once if safe. If the breaker trips or the code returns, do not keep resetting it.

When to call a pro

Call an authorized Panasonic dealer if F 98 returns. Tell them Panasonic lists F 98 as total running current protection.

Repair vs replace

Current-protection faults may involve power, boards, fan, or compressor diagnosis; compare major electrical/compressor repair with replacement on older systems.
