Master Ignition cable 09CA036130

Master Ignition cable 09CA036130 is a silicone-insulated ignition cable designed for use in Master burners and boilers. It connects the ignition transformer to the ignition electrode, carrying the high-voltage pulse that creates the spark to ignite the fuel-air mixture. This cable is compatible with Master models 4110.490, BV110, BV170, BV290, B230, and B360. The OEM equivalent part number is 4110.490.

When selecting a replacement ignition cable of this type, ensure the connector pattern at both ends matches the transformer output and electrode boot. The cable length must correspond to the original run. Always inspect the insulation condition during service; replace if stiffness, cracks, or carbon tracking are present.

Failure of ignition cables typically manifests as a hardened or cracked insulation, allowing the spark to leak to earth. This can mimic a failing ignition transformer and cause nuisance lockouts. Degraded insulation may compromise spark energy, delay flame establishment, and lead to burner control lockout. If the cable is suspect, replace it before diagnosing the transformer.
