ICP Gas Valve Support Bracket for RGS120LDAA0AAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket (Part No. 1178238) is the steel mounting bracket that secures the gas valve assembly inside your ICP / Tempstar / Heil RGS120LDAA0AAA gas furnace. It holds the valve in its correct position and orientation relative to the manifold and burners, isolating it from vibration and maintaining proper alignment of the gas piping. While the bracket itself rarely fails electrically, it can corrode, bend, or break during service or transit, and a damaged or missing bracket can leave the gas valve unsupported and stress the manifold connections. Replacing the bracket restores secure, correctly aligned mounting of the gas valve.
