Description
The Trane IGN00005 Ignitor/Spark Plug is designed to initiate the burner part during heating operation in HVAC systems. It is used in gas furnaces, rooftop units, and packaged heating equipment where it generates the spark required to ignite the fuel-air mixture inside the burner assembly. It operates as part of the ignition sequence by working with the control board and gas valve to support a consistent burner startup. It is replaced during maintenance or repair when ignition failure, inconsistent sparking, or burner startup issues affect heating performance.
