When you are out on a call for Trane package rooftop units (RTUs) and find a cracked or failed hot surface ignitor, the Trane KIT3033 Ignitor Kit is the exact 120V OEM solution needed to restore system firing. This kit, commonly identified by its 231T ignitor stamp, is a direct drop-in replacement for residential and light commercial Trane and American Standard gas furnaces. It is functionally identical to KIT03033 and replaces older iterations like IGN00051 and IGN00052. Engineered for silicon carbide performance, this hot surface ignition (HSI) kit includes the essential gaskets, mounting screws, and bracketry required for a clean install. For technicians working on Trane YCD150, YCD170, or YCD180 models, this OEM furnace igniter ensures optimal cold-start reliability and proper current draw, typically measuring between 40 and 100 cold ohms. Maintaining HVAC burner ignition integrity with genuine parts prevents the frequent "no-heat" callbacks associated with brittle, off-brand alternatives that do not meet Trane's technical specifications. Key Benefits for the Contractor Exact Compatibility: Designed specifically for Trane package units starting with YCD15, YCD17, and YCD18 prefixes. Complete Replacement Kit: Includes the 231T element, specialized gasket, and physical mounting hardware to ensure a secure air-tight seal in the burner box. OEM Performance: Eliminates the guesswork regarding voltage and resistance, providing a stable 120V ignition cycle. Cross-Reference Ready: Serves as a 1:1 replacement for KIT03033, 30NX22, and AF3033. Common Questions & Technical Insights Can I use this in place of a KIT03033? Yes, the KIT3033 is identical in form and function to the KIT03033 and is fully interchangeable in all documented applications. Why does my ignitor keep burning out? Always handle the silicon carbide element by the ceramic base. Oils from your skin can cause localized hot spots, leading to premature fracture. Also, verify you have 120V at the lead during the ignition sequence. Does this include the connector? This kit typically features a 2-pin Molex-style plug and 5-inch wire leads, allowing for a fast furnace repair without wire stripping.
