Panasonic Air Conditioner F94 error code

Difficulty: Hard · Cost: $100–$400 · Duration: Requires professional service

The F94 error means your Panasonic air conditioner's compressor discharge pressure protection has activated — the pressure of the hot refrigerant gas leaving the compressor has exceeded the safe limit. This protective shutdown prevents the compressor from being damaged by excessive pressure. Common causes include a dirty condenser coil, poor ventilation around the outdoor unit, or a refrigerant overcharge. A qualified technician will need to inspect and resolve the high pressure condition.

Common causes

  • Outdoor condenser coil is dirty reducing heat dissipation and causing high discharge pressure
  • Outdoor unit is in a poorly ventilated space trapping heat
  • Refrigerant is overcharged
  • Outdoor fan is not operating correctly reducing condenser cooling

How to fix it

  1. 1

    Turn off the unit at the circuit breaker

  2. 2

    Check that the outdoor unit has adequate clearance and ventilation

  3. 3

    Contact a qualified technician to clean the condenser coil, check refrigerant charge, and inspect the outdoor fan
