Overview
This is the OEM ECM X-13 motor control module for the ICP / Tempstar / Heil WJA342000KTP0B1, OEM part number 1185846 (ECM X-13 MTR CONTROL 1/2 HP). The X-13 is a constant-torque electronically commutated motor (ECM) control rated at 1/2 HP that drives the indoor blower at programmed speed taps. It is far more efficient than a legacy PSC motor and holds airflow steady against changing static pressure. The control module is the electronics end of the ECM assembly — when it fails the blower runs erratically, sticks on one speed, or stops entirely, producing weak airflow, no-heat / no-cool comfort complaints, or blower-fault codes at the furnace control board.

Compatibility
Direct OEM replacement for the ICP / Tempstar / Heil model WJA342000KTP0B1. The 1/2 HP ECM X-13 control is used across numerous ICP-family furnaces and air handlers built on the X-13 blower platform. Confirm horsepower, the X-13 designation, and the speed-tap configuration against your existing module before ordering.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before touching the motor.
- Access — Remove the blower-compartment service panel and slide out the blower assembly if needed.
- Document — Photograph the high-voltage harness and the low-voltage speed-tap plug positions before disconnecting.
- Remove — Unplug the power and control connectors, then separate the failed control module from the motor end shield.
- Install — Fit the new X-13 control to the motor, reconnect the power harness and speed-tap plug exactly per your photo.
- Test — Restore power and confirm the blower ramps to the correct speed on a heat and cool call.
Signs You Need a Replacement
- Blower runs intermittently, surges, or will not start.
- Weak or no airflow despite a clean filter and open registers.
- Blower stuck on a single speed regardless of heat/cool demand.
- Furnace control board reporting a blower or motor fault code.
