Description
The S1-025-38951-000 is a genuine OEM ignitor assembly (spark ignitor) produced by York for use in gas-fired furnaces and HVAC heating systems. This ignitor — with its 34-inch lead wire — is responsible for generating the spark that ignites the gas/air mixture inside the furnace burner. When the furnace calls for heat, the ignitor produces the high-voltage spark needed to start combustion, allowing the burners to light and the furnace to begin producing heat.
Key Features
- Lead Length: 34 inches — gives flexibility for installation and wiring when replacing older ignitors.
- Function: Produces the high-voltage spark necessary to ignite the gas/air mixture in a furnace burner — initiates safe combustion.
- Compatibility: Designed to fit compatible York-brand gas furnaces that accept this ignitor — intended as a direct replacement without modifications.
- Use Case: Ideal when the existing ignitor is cracked, broken, failing to spark, or in maintenance/replacement scenarios where ignition performance is compromised.
