Panasonic Air Conditioner F96 error code

Difficulty: Hard · Cost: $150–$400 · Duration: Requires professional service

A qualified technician will need to inspect the cooling of the transistor module and the outdoor unit.

Common causes

Outdoor unit heat sink is dirty reducing cooling efficiency
Outdoor unit is in a poorly ventilated enclosed space
Outdoor unit cooling fan is not operating correctly
Power transistor module has developed a fault

How to fix it

1

2

Check that the outdoor unit has adequate clearance and ventilation
3

Contact a qualified technician to clean the heat sink, inspect the transistor module, and check the outdoor fan
