14.4.19 F95 (Cooling High Pressure Abnormality)

Malfunction Decision Conditions

During operation of cooling, when outdoor unit heat exchanger high temperature data (61°C) is detected by the
outdoor pipe temperature sensor.

Malfunction Caused

•

Outdoor pipe temperature rise due to short circuit of hot discharge air flow.

•

Outdoor pipe temperature rise due to defective of outdoor fan motor.

•

Outdoor pipe temperature rise due to defective outdoor pipe temperature sensor.

•

Outdoor pipe temperature rise due to defective outdoor unit PCB.

Troubleshooting

Is outdoor fan motor operating?

When F95 indication happens

For safety reason and to prevent component
breakdown, always switch off the power
before remove and connect the component.

Check the outdoor unit installation
condition (during cooling or soft-dry
operation

•

Replace the outdoor fan motor.

YES

Is there any improper heat radiation?

•

Replace

compressor

•

Reinstall the outdoor unit

•

Remove the obstacle(s)

•

Clean the outdoor heat exchanger

Check the outdoor pipe temperature
sensor.

Does it conform to the sensor
characteristic charts?

•

Replace outdoor unit PCB

YES
