ICP X-13 ECM Fan Motor Control for WJA342000KTP0A1 — 1/2 HP | Ships Today

Overview

The OEM ICP part 1185846 is an X-13 ECM motor control module rated at 1/2 HP, used as the constant-torque blower drive on ICP/Heil/Tempstar gas furnaces and air handlers including model WJA342000KTP0A1. Unlike a standard PSC motor, the X-13 is a programmed-tap ECM that holds steady torque across changing static pressure, delivering quieter operation and lower electricity draw. When this control fails you typically see a blower that won't start, runs at one fixed speed, hunts up and down, or trips on the control board. This is a direct factory replacement preset to the original equipment airflow taps.
