ICP Gas Valve Support Bracket for RGS121HSCA0AAA — OEM Furnace Mounting | Ships Today

Overview

This OEM gas valve support bracket (part number 1178238) is the factory mounting hardware that secures the gas valve assembly inside your ICP / Tempstar / Heil RGS121HSCA0AAA gas furnace. The bracket holds the valve in correct alignment with the manifold and burner inlet so the gas train stays rigid under vibration and thermal cycling. A bent, corroded, or missing bracket lets the valve sag, which can stress the gas line connections, cause manifold misalignment, and create the conditions for a gas leak. This is a direct-fit replacement that matches the original geometry exactly.

Specifications

Compatibility

Engineered for the ICP-family RGS121HSCA0AAA gas furnace and the shared Tempstar, Heil, and Comfortmaker platforms that use the same gas train layout. Always confirm your model and serial tag 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.
3. Document — Photograph the gas valve, bracket, and tubing routing before disconnecting anything.
4. Remove — Loosen the gas valve from the old bracket, remove the mounting screws, and lift out the worn bracket.
5. Install — Mount the new bracket in the factory position, reseat the gas valve, and torque all fasteners per the photo.
6. Test — Restore gas and power, then leak-check every joint with soap solution and confirm a clean burner ignition.

Signs You Need a Replacement

• Gas valve sagging, loose, or vibrating in the cabinet
• Visible rust, cracks, or deformation on the bracket
