ICP Gas Valve Support Bracket for RGS121SRCB0AAA — OEM Mounting Bracket | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121SRCB0AAA gas furnace. The bracket is the formed-metal support that rigidly mounts the gas valve assembly inside the furnace, holding it in correct alignment with the manifold and burner orifices. Proper support prevents the gas valve from sagging or shifting, which can strain the inlet/outlet gas connections and the manifold gas-tight joints. A bent, corroded, or missing bracket can allow movement that stresses pipe threads and risks a gas leak. Replacing it with the exact OEM bracket restores correct valve positioning during furnace service or a gas valve swap.

Specifications

Compatibility

Built for the ICP-family RGS121SRCB0AAA and shared across many Tempstar, Heil, Comfortmaker, and ICP gas furnaces that use the same gas valve and manifold layout. Confirm the bracket part number against your unit before ordering.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect electrical power; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel to reach the gas valve and manifold.
3. Document — Photograph the bracket position and gas valve orientation before removal.
4. Remove — Support the gas valve, then unfasten the old bracket from the chassis.
5. Install — Mount the new bracket, secure the gas valve to it, and confirm proper manifold alignment.
6. Test — Restore gas and power, then leak-test all gas joints with soap solution and confirm normal ignition.

Signs You Need a Replacement
