Description
The Robertshaw 41-403 Hot Surface Ignitor 5-1/2″ 271M is an essential ignition component used in gas-fired equipment to initiate combustion in commercial heating systems. It generates heat when electrical current is applied, allowing gas burners in furnaces and heating components to ignite safely without a standing pilot light. The ignitor is installed within the burner assembly and operates as part of the ignition system sequence, controlled by the furnace control board of HVAC systems. It supports accurate system startup and consistent operation in the temperature-controlled indoor environments within systems.
