ICP Gas Valve Support Bracket for RGS120HDAB0AGAA Furnace | Ships Today

Overview

This OEM gas valve support bracket (part #1178238) is the mounting bracket that secures the gas valve and manifold assembly inside the ICP / Tempstar / Heil RGS120HDAB0AGAA gas furnace. It holds the valve rigidly in position so the burner manifold stays aligned and the gas-line connections aren't stressed by vibration or handling. A bent, corroded, or missing support bracket lets the gas valve and manifold flex, which can misalign the burner orifices, strain the pipe threads, and create the conditions for a gas leak. Replacing a damaged bracket restores proper valve support and correct burner alignment.

Specifications

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power; verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the bracket, valve orientation, and manifold position before disturbing anything.
4. Remove — Support the gas valve, remove the fasteners holding the old bracket, and take the damaged bracket out.
5. Install — Position the new bracket, fasten it securely, and confirm the gas valve and manifold sit in their original alignment.
6. Test — Restore gas and power, leak-check every joint with soap solution, and run a heat cycle to confirm correct burner operation.

Signs You Need a Replacement
