Robertshaw 41-802N Hot Surface Igniter

The Robertshaw 41-802N is a silicon nitride hot surface igniter designed as an OEM replacement for gas-fired heating equipment. It operates on a 120V AC supply and features a flat blade tip style for direct burner engagement.

Verify voltage and lead length before ordering

Confirm that the appliance requires a 120V AC igniter and that the 2 1/2 inch lead length reaches the control module without splicing. The hardwired electrical connection requires secure termination inside the appliance junction area.

Silicon nitride element tolerates 392°F lead

The heating element uses silicon nitride for reliable ignition cycles while the lead wire insulation is rated to 392 degrees F. Normal operation keeps the probe at high temperature but the hardwired leads remain within their thermal limit.
