ICP Gas Valve Support Bracket for RGS121HSAA0AAAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (OEM part 1178238) secures and stabilizes the gas valve and manifold assembly inside your ICP RGS121HSAA0AAAA furnace. The bracket holds the valve in proper alignment with the burner manifold so the gas orifices stay correctly positioned over the burners, and it prevents stress on the gas piping and valve body from vibration during operation. A bent, corroded, or missing bracket can allow the valve to sag or shift, leading to misaligned burners, gas line strain, and noisy operation. Replacing it with the correct OEM bracket restores a secure, factory-spec mount.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power, and verify zero voltage with a multimeter.

3. Document — Photo the bracket, valve, and manifold orientation before disturbing anything.
4. Remove — Support the gas valve, remove the bracket fasteners, and lift out the old bracket. Do not let the valve hang from the gas line.
5. Install — Position the new bracket, fasten it to the cabinet and valve, and confirm the manifold and orifices align over the burners.
6. Test — Restore gas and power, leak-check all joints with soapy solution, and run a heat cycle to verify proper burner operation.
