ICP X-13 ECM Fan Motor Control for WJA342000K000B1 — 1/2 HP | Ships Today

Overview

The OEM ICP part 1185846 is an X-13 ECM motor control module rated at 1/2 HP, serving as the constant-torque blower drive on ICP/Heil/Tempstar gas furnaces and air handlers including model WJA342000K000B1. The X-13 is a programmed-tap ECM that maintains steady torque as static pressure changes, giving quieter airflow and lower power consumption than a legacy PSC motor. Failure symptoms include a blower that won't start, runs at a single fixed speed, surges, or faults out at the control board. This is a direct factory replacement preset to the original airflow taps.
