ICP Gas Valve Support Bracket for RGS120LSAB0AAA | Ships Today

Overview

Note: Despite being listed under the gas valve category, OEM part #1178238 is a gas valve support bracket — a mounting bracket, not a gas valve. It is the genuine OEM metal bracket that holds the gas valve in its correct position inside the ICP / Tempstar / Heil RGS120LSAB0AAA gas furnace. The bracket keeps the valve rigidly aligned with the manifold and burners so the gas connections stay leak-free and the valve does not move under vibration.

This bracket is typically replaced when it is bent, corroded, or damaged during a prior gas valve service, or when the original is missing. A loose or damaged support bracket can stress the manifold connection and allow the valve to shift, which is a safety concern on a gas appliance.

Specifications

Compatibility

OEM support bracket for the gas valve assembly in the ICP/Tempstar/Heil RGS120LSAB0AAA and related ICP-family furnaces that used bracket 1178238. The gas valve itself is sold separately. Confirm bracket geometry against your manifold before ordering.

Installation Guide

1. Safety First – Shut off the gas supply, disconnect power, and verify zero voltage with a multimeter.
2. Access – Remove the burner-compartment service panel.
3. Document – Photograph the bracket position and valve orientation before disturbing anything.
4. Remove – Support the gas valve, then remove the fasteners holding the old/damaged bracket.
5. Install – Position the new bracket, secure the gas valve to it, and reconnect per your photos. Do not over-torque the valve body.
6. Test – Restore gas, then leak-check all joints with soap solution before restoring power and running a heat cycle.

Signs You Need a Replacement

• Bent, cracked, or corroded existing bracket.
• Gas valve shifts or vibrates because the bracket no longer holds it.
• Original bracket missing after a prior valve replacement.
