Product Identity

The Robertshaw 41-406 is a 120 V AC hot surface ignitor designed as a universal replacement for gas-fired heating systems. It uses a silicon carbide heating element and installs via hardwired connections with an 11 in lead length.

What the Universal Design Changes

A flat-tip probe measuring 2 in fits a wide range of burner assemblies, reducing the need to match exact OEM part numbers. The lead insulation is rated to 392 °F, so the wiring withstands the high temperatures found inside furnace cabinets.

Who This Suits and Who It Does Not

HVAC technicians and homeowners repairing a failed ignitor on compatible 120 V equipment will find this a direct, plug-and-play solution. Buyers whose systems require a different voltage, a non-flat tip geometry, or a longer lead wire should look for a model that matches those specifications.

Questions about this item

How often does the silicon-carbide heating element need replacement?

The ignitor is a universal replacement part; silicon-carbide elements typically last several heating seasons before requiring a new unit.

What limits continuous operation first — lead-wire temperature or probe length?

Lead-wire insulation is rated to 392 Degrees F, so sustained heat at the 2 in probe usually reaches that limit before probe length becomes a factor.

Does the hard-wired 120 V AC connection run hot or noisy during all-day cycles?

The flat-tip silicon-carbide ignitor operates silently; heat is concentrated at the 2 in probe while the 11 in leads stay within the 392 Degrees F insulation rating.
