It steps the 208\/230V line voltage down to the 24V control circuit that powers the contactor coil, thermostat, and safety switches. Rated at 40VA, it supplies the steady, regulated low-voltage current your system needs to energize controls reliably on every call for cooling. This listing includes both the transformer (OEM part 1173691, TRANS 208\/230\u0026gt;24 40VA) and the 24V barrier (OEM part 1176032) that isolates and protects the line- and low-voltage terminals. When a control transformer fails, the entire 24V circuit goes dead — the contactor won't pull in, the unit won't start, and the thermostat may appear unpowered. Common failure causes include a shorted thermostat wire, an overloaded control circuit, voltage spikes, or simple age-related winding breakdown.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1173691 (transformer), 1176032 (24V barrier)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eControl \/ step-down transformer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP (Tempstar \/ Heil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRating\u003c\/td\u003e\n\u003ctd\u003e40 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e208\/230V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary Voltage\u003c\/td\u003e\n\u003ctd\u003e24V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM direct replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDirect OEM-fit replacement for the ICP WJA360000K000B1 condensing unit and its sibling builds across the ICP family of brands, including Tempstar, Heil, Comfortmaker, and Arcoaire models that share the same 208\/230V control platform.
