Description

This ignition transformer converts the appliance's supply to the high-voltage pulse needed to create sparks for gas burners or oven igniters, restoring reliable spark generation when the original unit fails. What it does:

• Generates the high-voltage ignition spark for surface burners or oven ignition systems.
• Replaces a failed or weak ignition transformer that causes no spark or intermittent sparking.
• Stops continuous clicking without ignition and helps ensure proper burner lighting.
• Works as the electrical interface between the appliance control and the spark electrodes.

What's included: One ignition transformer (part number 00631974). Install notes:

• Disconnect electrical power and shut off the gas supply before starting work.
• Label and photograph wire connections before removing the old transformer to ensure correct reassembly.
• Handle terminals and wiring carefully; avoid shorting high-voltage connections.
• After installation, restore power and test all burners/igniters for consistent spark and proper operation.
