ICP Gas Valve Support Bracket for RGS121LRAB0AAAA — OEM | Ships Today

Overview

This OEM ICP gas valve support bracket (part number 1178238) is the mounting bracket that holds the gas valve and manifold assembly securely in position within the RGS121LRAB0AAAA furnace. A rigid, correctly aligned bracket keeps the valve, manifold, and burner orifices in proper relationship so gas is delivered cleanly to each burner. A corroded, cracked, or bent bracket allows the manifold to sag or shift, which can misalign the burners, stress the gas-line connections, and cause noisy or uneven ignition. Replacing the bracket with the exact OEM part restores correct manifold geometry and a safe, secure mount.
