The X-13 is a programmed electronically commutated motor that holds a constant torque across a range of static pressures, delivering quieter, more efficient airflow than a traditional PSC blower. The control accepts low-voltage tap signals from the system board to select the programmed airflow profile for heating, cooling, and fan-only operation. When this module fails, the blower may not run, run only on one speed, surge or hunt, or shut down on internal overload. Because the motor and electronics are an integrated assembly, a failed control module typically means the blower stops moving air entirely — leading to no heat, no cool, or a system that trips on high limit. Replacing with the correct OEM control preserves the factory airflow programming for the cabinet.\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 Number\u003c\/td\u003e\n\u003ctd\u003e1185846\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eECM X-13 Constant-Torque Motor Control\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\u003eHorsepower\u003c\/td\u003e\n\u003ctd\u003e1\/2 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eFurnace \/ Air Handler Blower\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFits Model\u003c\/td\u003e\n\u003ctd\u003eWJA342000K000A2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eThis X-13 control is the OEM blower motor module for the ICP WJA342000K000A2 and the matching 1\/2 HP blower assemblies used across equivalent Tempstar, Heil, and Comfortmaker air handlers and furnaces.
