Symptoms and Causes
Failure code # 03 indicates ignition failure
of the combustion device
1
In case there is no combustion and failure
code # 03 is displayed
1) Gas supply is not normal.
2) Ignition transformer is not working.
3) Space between electrodes and
discharge.

- Check supply pressure and call the gas
company if not normal.
- Check power supply from the controller to the
ignition transformer.
- If there is no power supply, replace the main
controller.
- If there is power supply but the ignition
transformer is not working properly, check for
coil short circuit. If the resistance shows an
infinite level, it is defective and needs to be
replaced.
- The secondary voltage should be 19.5kV and if
it comes out weak, the ignition transformer has
to be replaced.
- Check whether crevice between electrodes is
2~3mm and adjust accordingly.
- Check whether the electrodes are not banded in
a direction.
