What causes error F96 on my Panasonic CS-S9NKR?
- TTravis RobinsonSep 18, 2025Error F96 on your Panasonic Air Conditioner indicates IPM overheating. This can happen because: * The IPM overheats due to a short circuit of hot discharge air flow, so investigate outdoor air flow for obstructions. * The IPM overheats due to a defective outdoor fan motor, so inspect and replace the outdoor fan motor if defective. * The IPM overheats due to defective internal circuitry of the IPM, so check and replace the IPM if defective. * The IPM overheats due to a defective IPM temperature sensor, so inspect and replace the IPM temperature sensor.
