Giersch 44-90-20636 cable for RG30

This ignition cable, listed under the Giersch brand with manufacturer codes 44-90-20636 and 507.298.002, is designated for the RG30 application and belongs to the ignition cables and connectors category. Ignition cables of this type carry the high-voltage output from the ignition transformer to the spark electrode. They are silicone-insulated to withstand the heat and voltage present in the burner environment. A damaged or aged cable—hardened, cracked, or with compromised insulation—can leak current to ground, which mimics a failing transformer and prevents reliable ignition. When selecting a replacement, the cable must match the connector pattern at both the transformer terminal and the electrode end. The length and the terminal type (e.g., spade, ring, or plug) must be appropriate for the physical layout. Always inspect the old cable for signs of brittleness or tracking marks; if the insulation is degraded, replace it regardless of whether a fault is currently present. The cable itself has no operational settings—it simply conducts the ignition spark—so the primary selection criteria are compatibility with the transformer and electrode connection, and adequate insulation condition.
