ICP Furnace Control Board Kit for RGS214LEAA0AAAA — OEM | Ships Today

Overview

This OEM control board kit (part #1183618) is the brain of the ICP / Tempstar / Heil RGS214LEAA0AAAA furnace. It manages the entire heating sequence — inducer startup, igniter warm-up, gas valve timing, flame sensing, and blower fan control — while monitoring safety limits and pressure switches. When the board fails, the furnace may short cycle, fail to ignite, leave the blower running constantly, or flash diagnostic fault codes. Sold as a complete kit, it ships with the mounting hardware and instructions needed for a clean swap, restoring proper ignition timing and safe, reliable operation.

Specifications

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil RGS214LEAA0AAAA and related RGS214 series gas furnaces. Confirm the part number against your existing board before ordering, as control boards are model-specific. The kit replaces the original integrated furnace control.

Installation Guide

1. Safety First — Disconnect electrical power and shut off gas, then verify zero voltage with a multimeter.
2. Access — Remove the furnace control-compartment door.
3. Document — Photograph every wire harness and connector position on the old board before unplugging anything.
4. Remove — Unplug each connector, release the mounting standoffs or screws, and lift out the old board.
5. Install — Mount the new board on the same standoffs and reconnect every harness to its matching terminal per your photos.
6. Test — Restore gas and power, run a full heat cycle, and confirm correct ignition, flame sensing, and blower timing with no fault codes.

Signs You Need a Replacement

• Furnace short cycles or will not begin the ignition sequence
• Blower runs continuously or never starts
• Diagnostic LED flashes a hard-fault or board failure code
