Robertshaw 41-410n Silicon Nitride Hot Surface Ignitor

Product Description

The ROBERTSHAW 41-410n is a silicon nitride hot surface ignitor designed to provide reliable ignition in gas-fired heating systems. Unlike older carbide-style ignitors, silicon nitride construction offers improved resistance to thermal shock and mechanical stress, making it a durable choice for residential and light commercial furnace applications. Licensed HVAC technicians install this ignitor as a direct replacement during heating season service calls or when diagnosing a no-heat condition caused by ignition failure.

The 41-410n is suited for use in gas furnaces where hot surface ignition is the specified ignition method. It fits into the burner assembly ignition circuit and operates on line voltage supplied through the furnace control board. This ignitor is typically installed during routine maintenance, equipment failure diagnostics, or as part of a heat exchanger or burner section service.

Key Features

• Silicon nitride construction provides superior resistance to thermal shock compared to silicon carbide ignitors
• Designed for gas-fired forced-air furnace ignition systems
• OEM-style replacement form factor for straightforward field installation
• Durable material reduces the risk of breakage during handling and installation

Compatibility

Designed as an OEM-style replacement hot surface ignitor for residential and light commercial gas furnaces that utilize a silicon nitride ignition element.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable local codes and the equipment manufacturer's service documentation. Always disconnect power to the furnace and shut off the gas supply before removing the existing ignitor. Handle silicon nitride ignitors with care to avoid cracking the element, and avoid touching the ignitor tip with bare hands as skin oils can affect performance. Verify correct ignitor positioning and secure mounting before restoring power and confirming ignition operation.
