Robertshaw 41-203 Igniter Overview

The Robertshaw 41-203 is a 120V AC igniter designed for gas-fired heating equipment. It includes two porcelain nuts for secure mounting and features a transparent body. This component suits HVAC technicians and maintenance staff replacing a worn igniter in compatible furnaces or boilers.

Replacing Worn Igniters

The unit replaces an existing igniter that has cracked or failed to spark reliably. A jump to this model is worth it when the original part shows carbon tracking or the ceramic insulator is damaged. The 11 1/2 in lead length must match the appliance wiring harness for a direct fit.

Fit For Direct Replacement

This igniter suits buyers who need a direct replacement with the same voltage and lead length. It is not for systems requiring a different input voltage or a shorter or longer lead. Buyers who need a different mounting style or a hot-surface igniter should look at other parts.

Questions about this item

What lead length does the Robertshaw 41-203 igniter have for reaching the burner assembly?

The igniter includes an 11 1/2 in lead that connects to the 120V AC supply, giving enough reach for most furnace burner compartments without splicing.

How is the Robertshaw 41-203 igniter mounted, and what step do installers often miss?

The igniter mounts with the two included porcelain nuts; the step often missed is tightening both nuts evenly so the ceramic element stays aligned and does not crack from uneven stress.

Which component of the Robertshaw 41-203 igniter typically requires replacement after repeated heating cycles?

The ceramic igniter element itself is the wear item; it becomes brittle after many ignition cycles and should be replaced when the furnace fails to light reliably.
