Intermittent sparking following ignition on any activated burner.
POTENTIAL CAUSES
Air drafts alter the flame shape pushing the
flame away from electrode. Momentary
loss of flame occurs and sparking is
initiated until flame is sensed again.
Foreign materials on the insulator of
electrodes cause undesirable leakage
currents effects, reducing the detected
flame strength.
Change in the relative position of the
electrode in the flame.
Dirty Burner Assembly
ACTION
7.1.1 Check surrounding environment for excessive drafts and minimize large drafts.
7.2.1 Check electrode for dirt, grease. Clean
7.2.2 Check environment for potential of condensation on electrode. Attempt to reduce effect.
7.2.3 Check electrode for fatigue, aging ( small cracks ) which make leakage current effects worse.
Replace electrode
7.3.1 Check position of the electrode relative to requirements of drawings, igniter electrode
height change during cooktop re-assembly and spark gap distance change.
7.3.2 Check gas regulator for problems reducing the pressure. Lower pressure results in smaller flame
which moves away from the detection electrode..
7.3.3 Check gas pressure to the regulator is within lower limit
7.3.4 Check gas lines to burners for any blockages, particularly on the simmer setting
7.3.5 Check gas-tap for any reduction of gas flow in the simmer setting. This setting is most prone to
intermittent sparking problem.
7.3.6 Check gas valve for blockages that can reduce gas pressure, gas flow
7.3.7 Check burner assembly for correct assembly of all components. Any misalignment could affect
flame shape and flame detection level.
7.4.1 Check cleanliness of burner assembly components. Any resides that add electrical resistance of
burner assembly to earthed chassis, reduces the flame strength and increase the intermittent
spark effect.
