ICP X-13 Control Board for WTA3422000RKA1 — Furnace/Air Handler Circuit Board | Ships Today

Overview

This OEM X-13 control board (part #1173692) manages the X-13 ECM blower motor and core control logic on your ICP/Tempstar/Heil WTA3422000RKA1 system. The board sequences blower speed taps, processes thermostat demand signals, and protects the motor circuit. A failed control board commonly produces no blower operation, erratic or stuck-speed blower behavior, blown control fuses, or a system that ignores thermostat calls. Because it directs the X-13 ECM motor, board faults often mimic motor failures — confirm board voltage outputs before condemning the motor.

Specifications

Compatibility

Direct OEM replacement for the ICP/Tempstar/Heil WTA3422000RKA1 air handler/furnace. Also used across ICP-family equipment built around the X-13 ECM blower platform. Match the board's part number and connector layout to your existing board before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter.
2. Access — Remove the blower compartment service panel.
3. Document — Photograph every plug, terminal, and speed-tap connection before disconnecting.
4. Remove — Unplug all harness connectors and low-voltage leads, then remove the board mounting screws/standoffs.
5. Install — Mount the new board, transfer each connector to the matching position per your photo, ensuring the X-13 motor harness is seated fully.
6. Test — Restore power and verify the blower starts and ramps correctly on a call for heat/cool.

Signs You Need a Replacement

• Blower will not run despite a valid thermostat call
• Blower stuck at one speed or cycling erratically
• Repeatedly blown low-voltage control fuse
• No 24V output to the motor or contactor from the board
