ICP Gas Valve Support Bracket for RGS120LFCA0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part #1178238) for the ICP/Tempstar/Heil RGS120LFCA0AAA gas furnace. The bracket rigidly mounts and supports the gas valve and manifold assembly inside the burner compartment, holding the valve in correct alignment with the manifold and burners so the gas connection stays leak-free and the burners fire evenly. A bent, corroded, or cracked bracket can let the valve and manifold shift, stressing the gas piping and threatening the seal at the valve connections. This stamped-steel replacement restores proper, secure mounting of the gas valve.

2. Access — Remove the burner compartment service panel.
3. Document — Photograph the gas valve, manifold, and bracket positions before disturbing anything.
4. Remove — Detach the gas valve/manifold as needed, then unbolt the old bracket from the cabinet.
5. Install — Fasten the new bracket, remount the valve/manifold, and reconnect the gas line with fresh approved sealant.
6. Test — Restore gas and power, then leak-check every joint with soap solution and confirm a clean burner light-off.
