ICP Gas Valve Support Bracket for RGS121LFAB0AAAA — OEM 1178238 | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121LFAB0AAAA gas furnace. The bracket anchors the gas valve to the furnace burner box, keeping the valve aligned with the manifold and burners. When the bracket corrodes, cracks, or loosens, the gas valve can shift and stress the manifold connection — causing uneven flames or, in the worst case, a gas leak. Installing the exact OEM bracket restores correct valve positioning and a sealed, safe gas train.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect electrical power. Verify zero voltage with a multimeter.
2. Access — Remove the furnace front service panel to expose the burner box and gas valve.
3. Document — Photograph the bracket orientation, gas valve, and wiring before disconnecting anything.
4. Remove — Loosen the manifold/valve as needed, remove the fasteners holding the old bracket, and lift it out.
5. Install — Mount the new bracket in the same orientation, secure the gas valve, and torque the manifold connection to spec.
6. Test — Restore gas and power, leak-test every joint with a gas-rated solution, and verify normal burner operation.

Signs You Need a Replacement
