The transformer steps line voltage down to a clean 24 VAC so the thermostat, contactor coil, and reversing-valve solenoid all operate reliably. Rated at 40VA, it provides enough capacity to hold these control loads in simultaneously without overheating. When the transformer fails, the entire low-voltage side goes dead: the thermostat screen may go blank, the contactor will not pull in, and in heat-pump mode the reversing valve will not shift. Common failure causes are a shorted thermostat wire, a stuck 24V relay or solenoid drawing excess current, or simple age and heat fatigue.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\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\u003eType\u003c\/td\u003e\n\u003ctd\u003eControl \/ Class 2 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\u003eSecondary Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VAC\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 \/ 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelated 24V Parts\u003c\/td\u003e\n\u003ctd\u003e1176148, 1172619, 1176137, 1173708\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eReplacement 24V control transformer for the ICP \/ Tempstar \/ Heil WPH3362000RKA1 heat pump and the 24V control circuit that drives its reversing valve coil, control relay, and barrier components.
