When the error code 'F9' appears, you can do the following to fix the problem:
- Check whether the resistance of sensor is normal, otherwise you'll need to replace it.
- Check whether the sensor wire is short circuit or open circuit, whether the plug is well contacted, whether there is welding off or rosin on the electric control board. If any of the following is true, you'll need to repair it.
- If everything (above) is okay and the problem is still occurring that indicates that the components or integrated circuit is damaged. This means you'll need to get a new electric control board.
