ICP Gas Valve Support Bracket for RGS120HRBA0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP/Tempstar/Heil RGS120HRBA0AAA gas furnace. The support bracket secures the gas valve assembly to the furnace manifold and burner box, holding the valve in correct alignment with the gas train and burners. A properly mounted valve prevents stress on the gas line connections, reduces vibration, and keeps the valve at the manufacturer-specified orientation for reliable ignition and combustion. Symptoms of a damaged, corroded, or missing bracket include a gas valve that shifts or sags, rattling or buzzing during operation, strained or kinked manifold tubing, and difficulty seating the valve during a repair. Replacing a worn bracket during a gas valve service ensures the new valve is mounted safely and to OEM specification.

4. Remove — Disconnect the gas line union if required, unfasten the gas valve from the old bracket, and remove the worn bracket from the burner box.
5. Install — Mount the new 1178238 bracket, reattach the gas valve in the original orientation, and reconnect the manifold per your photos.
6. Test — Restore gas and power, leak-check all connections with soap solution, and verify normal ignition and burner operation.
