ICP Gas Valve Support Bracket for RGS121HFCA0AAA – OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP Tempstar Heil RGS121HFCA0AAA gas furnace. The support bracket holds the gas valve and manifold assembly in its correct, rigid position so the burners line up properly and the gas piping is not stressed. A bent, cracked, or missing bracket allows the valve and manifold to sag or shift, which can misalign the burner flames, strain the gas line connection, and create vibration or rattling during operation. This OEM bracket restores factory mounting geometry and is a direct bolt-in replacement.

Specifications

Compatibility

Engineered for the ICP Tempstar Heil RGS121HFCA0AAA and related ICP-family gas furnaces that use OEM part 1178238. Verify the part number and bracket shape against your existing component before ordering, as manifold and valve geometry varies across furnace platforms.

2. Access – Remove the furnace burner-compartment service panel.
3. Document – Photograph the valve, manifold, and bracket positions before removing anything.
