ICP Gas Valve Support Bracket for RGS121HSBB0AAAA — OEM Mounting Bracket | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121HSBB0AAAA furnace. The bracket mounts and stabilizes the gas valve inside the burner compartment, holding it in correct alignment with the manifold and burner assembly so the gas train remains rigid through years of thermal cycling. A loose, cracked, or corroded bracket lets the gas valve sag or vibrate, which can stress the manifold connection, cause noisy operation, and in severe cases create a leak path at the threaded joints. Replacing a damaged bracket restores a secure, factory-spec mount.

Specifications

Compatibility

Designed as a direct-fit replacement for the ICP / Tempstar / Heil RGS121HSBB0AAAA gas furnace and other models in the same family that share the 1178238 bracket. Always confirm the OEM part number stamped on your existing bracket before ordering.

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/burner service panel.
3. Document — Photograph the gas valve, bracket position, and all wiring before disconnecting anything.
4. Remove — Disconnect the gas valve from the manifold and unbolt the old support bracket from the furnace chassis.
5. Install — Fasten the new bracket, remount the gas valve, and reconnect the manifold using fresh thread sealant rated for gas.
6. Test — Restore gas and power, leak-test all joints with soap solution, and verify normal ignition and operation.

Signs You Need a Replacement

• Visible cracks, bends, or corrosion on the existing bracket
• Gas valve sags, shifts, or vibrates audibly during operation
