ICP Gas Valve Support Bracket for RGS121LFBA0AAAA — OEM 1178238 | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121LFBA0AAAA gas furnace. The bracket secures the gas valve assembly to the furnace burner box, holding the valve in correct alignment with the manifold and burners. A loose, corroded, or cracked bracket lets the gas valve shift, which can stress the manifold connection, cause misaligned flames, or create a gas leak risk. Replacing a damaged bracket with the exact OEM part restores proper valve positioning and a safe, sealed gas train.

Compatibility

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 any attached wiring before disconnecting anything.
4. Remove — Loosen the manifold/valve as needed, then remove the fasteners holding the old support bracket and lift it out.
5. Install — Mount the new bracket in the same orientation, secure the gas valve, and torque the manifold connection per spec.
6. Test — Restore gas and power, then leak-test all joints with a gas-rated solution and verify normal burner operation.

Signs You Need a Replacement

• Gas valve sits loose, tilted, or shifts when touched
