Bosch 239-47954-00 Igniter 2.75 Inches

Product Description

The BOSCH 239-47954-00 is a replacement igniter designed to initiate combustion in gas heating systems. The igniter generates the heat or spark required to light the burner assembly at the start of each heating cycle. This component is a direct OEM-style replacement intended for installation by licensed HVAC technicians and qualified heating contractors performing routine service or emergency repair work. At 2.75 inches in length, it is a compact component suited for residential gas furnace applications.

This igniter is typically found in gas furnace systems where a failed or cracked igniter is causing a no-heat condition. When the control board calls for heat and the igniter fails to reach proper operating temperature or produce a reliable spark, the unit will lock out. Replacing the igniter with the correct OEM part number restores normal ignition sequencing and prevents nuisance lockouts.

Key Features

• OEM replacement igniter for BOSCH gas heating systems
• Compact 2.75-inch form factor for fitment in tight furnace cabinets
• Restores proper ignition sequencing to eliminate no-heat lockout conditions
• Direct replacement using original BOSCH part number 239-47954-00

Compatibility

Designed as an OEM-style replacement igniter for BOSCH gas furnace systems. Verify fitment against the unit model number and existing igniter part number before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off power to the furnace at the disconnect switch and turn off the gas supply before beginning any igniter service. Handle the igniter element carefully, as oils from bare skin contact can cause premature failure on silicon nitride or hot-surface igniter types. Follow all applicable local codes and the manufacturer service documentation during replacement.
