The X-13 is a programmed electronically commutated motor that maintains a constant torque across changing static pressure, delivering quieter, more efficient airflow than a traditional PSC blower. The control reads low-voltage tap signals from the system board to select the programmed airflow profile for heating, cooling, and continuous-fan operation. When this module fails, the blower may not run at all, run on a single speed, surge or hunt, or shut down on internal overload. Because the motor and electronics form an integrated assembly, a failed control typically stops airflow entirely — causing no heat, no cool, or high-limit trips. Installing the correct OEM control preserves the factory airflow programming for this 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\u003eWJA342000K000A1\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 WJA342000K000A1 and the matching 1\/2 HP blower assemblies used across equivalent Tempstar, Heil, and Comfortmaker air handlers and furnaces.
