Step 1
①Check if power comes on.
②Check if any Sparks are coming from the Electrode.
Step 2
①If there are no Sparks, Check the Electrode & Spark module wiring.
②Check the Electrode wire for signs of melting or other damage.
③Check the Electrode fastening clip and Electrode fixed state.
④Make sure there are no movements of the Electrode
(In the case of Wire melting, sparks will come out of the melted area and
it will fail to ignite)
Check Point “Electrode wire and fastening Clip conditions” inspection.
Tip 1-1. Electrode Inspection
