Robertshaw 41-407n Silicon Nitride Hot Surface Ignitor

Product Description

The ROBERTSHAW 41-407n is a silicon nitride hot surface ignitor designed for use in gas-fired heating systems. Silicon nitride ignitors are known for their durability and resistance to thermal shock compared to older silicon carbide designs. This ignitor generates the heat required to ignite the gas burner during each heating cycle. It is typically installed by a licensed HVAC technician as part of routine service or a no-heat diagnosis on a gas furnace.

This ignitor is suited for residential gas furnace applications where a hot surface ignition system is used in place of a standing pilot or spark ignition setup. It serves as a direct replacement component in systems that call for a silicon nitride ignitor. Consult the furnace manufacturer's documentation to confirm fitment before installation.

Key Features

• Silicon nitride construction offers improved thermal shock resistance compared to silicon carbide ignitors
• Designed for hot surface ignition systems in gas-fired furnaces
• OEM-style replacement form factor for straightforward serviceability
• Compatible with standard low-voltage ignition control circuits

Compatibility

Designed as an OEM-style replacement hot surface ignitor for residential gas furnaces equipped with silicon nitride ignition systems.

Installation Notes

Hot surface ignitors are installed by licensed HVAC technicians. Always disconnect power and shut off the gas supply to the furnace before servicing the ignition system. Handle silicon nitride ignitors carefully to avoid contamination from skin oils, which can shorten service life. Verify the ignitor's electrical resistance and confirm proper seating in the burner assembly before restoring power.
