ICP Gas Valve Support Bracket for RGS121SFCA0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121SFCA0AAA gas furnace. The bracket secures the gas valve assembly inside the burner compartment, holding it in correct alignment with the manifold and burners so the valve seats properly and does not vibrate loose during ignition cycles. A cracked, corroded, or missing bracket lets the gas valve shift, which can stress the manifold connection, cause flame instability, or trigger nuisance lockouts. This stamped-steel bracket is a direct-fit replacement that mounts in the original location with the original fasteners.

Installation Guide

1. Safety First — Shut off gas at the manual shutoff, disconnect electrical power, and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the gas valve, bracket position, and any attached wiring before disconnecting.
4. Remove — Loosen the gas line union and manifold fasteners as needed, then unbolt the old bracket from the cabinet and free the gas valve.
5. Install — Mount the new bracket in the original location, reattach the gas valve and manifold, and torque fasteners snugly.
6. Test — Restore gas and power, leak-check all joints with soap solution, and verify a clean ignition and steady flame.
