ICP Gas Valve Support Bracket for RGS120SFBA0AGAA — OEM Part 1178238 | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP/Tempstar/Heil RGS120SFBA0AGAA gas furnace. The bracket secures the gas valve to the burner assembly and manifold, holding it in correct alignment so the valve, manifold, and burner orifices stay properly positioned during operation. A loose, corroded, or bent bracket lets the gas valve shift, which can stress the manifold connections, create gas-line strain, and produce rattling or vibration during ignition and burner operation. Replacing a damaged bracket restores a rigid, factory-correct mount and protects the more expensive gas valve from movement-related fatigue.

Specifications

Compatibility

Designed for the ICP RGS120SFBA0AGAA furnace and shared-platform Tempstar, Heil, and Comfortmaker models that use the same burner/manifold assembly. Always confirm your gas valve and manifold layout match before ordering.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power to the furnace. Verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the gas valve, bracket, and manifold orientation before removing anything.
4. Remove — Loosen the gas valve mounting screws, then remove the fasteners holding the old support bracket. Do not over-stress the gas line.
5. Install — Position the new 1178238 bracket, fasten it, and re-secure the gas valve in its original alignment per your photo.
6. Test — Restore gas and power, then leak-check all gas connections with soap solution and verify normal burner ignition.

Signs You Need a Replacement

• Gas valve moves, sags, or rattles during operation
