It steps the incoming 208\/230V line down to the 24V control signal that operates the contactor coil, reversing valve, defrost board, and thermostat circuit. Rated at \u003cstrong\u003e40VA\u003c\/strong\u003e, it includes OEM part \u003cstrong\u003e1173691 (TRANS 208\/230\u0026gt;24 40VA)\u003c\/strong\u003e and the matching \u003cstrong\u003e1176148 terminal barrier (BARRIER 24V 42-60)\u003c\/strong\u003e that protects the low-voltage terminals. When a transformer fails the entire control circuit goes dead — the unit will not energize the contactor, the air handler stays off, and the thermostat display may go blank. A buzzing transformer, a tripped low-voltage fuse, or scorched secondary terminals are all signs of a failing unit.\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\u003eOEM Part Numbers\u003c\/td\u003e\n\u003ctd\u003e1173691, 1176148\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eStep-down control 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\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\u003eRating\u003c\/td\u003e\n\u003ctd\u003e40VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003ctd\u003e24V terminal barrier (42-60)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eEngineered as a direct-fit replacement for the ICP \/ Tempstar \/ Heil \/ Comfortmaker \u003cstrong\u003eWPA3424000RKC1\u003c\/strong\u003e condenser.
