ICP Gas Valve Support Bracket for RGS120SEAB0AAA – OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket, factory part number 1178238, for ICP/Tempstar/Heil gas furnaces. It is the formed sheet-metal mount that holds the gas valve and manifold assembly rigidly in position inside the burner compartment. It is not the gas valve itself — it is the structural bracket the valve bolts to. A bent, corroded, or cracked bracket can let the valve and manifold shift, misaligning the burners and orifices, which leads to poor flame, ignition complaints, or rattling during operation. Replace the bracket when it's damaged or when a previous valve service left the mount distorted.

Specifications

Compatibility

Direct fit for ICP, Tempstar, Heil, and Comfortmaker gas furnaces including model RGS120SEAB0AAA. Confirm the bracket profile against your existing mount before ordering, as manifold layouts vary by furnace family.

Installation Guide

1. Safety First – Shut off the gas supply and disconnect electrical power; verify zero voltage with a multimeter.
2. Access – Remove the burner compartment service panel.
3. Document – Photograph the valve, manifold, and bracket orientation before disturbing anything.
4. Remove – Disconnect the gas line union and manifold as needed, then unbolt the old bracket from the cabinet.
5. Install – Bolt in the new bracket, remount the gas valve/manifold, and reconnect the gas line.
6. Test – Restore gas and power, leak-check all joints with soap solution, and verify a clean burner ignition.
