ICP ECM X-13 Fan Motor Control for WAHA30114A1 — 1/3 HP | Ships Today

Overview

This is the genuine OEM ECM X-13 motor control (part number 1185274), a 1/3 HP constant-torque variable-speed blower motor used in ICP, Tempstar, and Heil air handlers and fan coils. The X-13 platform delivers programmed constant airflow across changing static pressure, improving comfort and efficiency over a traditional PSC motor. When this motor or its integrated control fails, the blower may run intermittently, fail to start, hum without spinning, or trip on thermal overload. Replacing it with the correct OEM 1/3 HP X-13 control restores proper airflow staging and quiet operation.

Specifications

Compatibility

Designed as the OEM blower motor control for the ICP / Tempstar / Heil WAHA30114A1 air handler. It also fits the WAHA series of fan coils that originally shipped with the 1185274 X-13 control. Always confirm your existing motor part number and HP before ordering.
