ICP Gas Valve Support Bracket for RGS121HSBA0AAAA — OEM Mounting Bracket | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121HSBA0AAAA furnace. The bracket mounts and stabilizes the gas valve inside the burner compartment, keeping it aligned with the manifold and burner assembly so the gas train stays rigid through repeated heat cycling. A bent, cracked, or corroded bracket allows the gas valve to sag or vibrate, stressing the manifold connection, creating noise, and in worst cases opening a leak path at the threaded joints. Installing a fresh bracket restores a secure, factory-spec mount.

Specifications

Compatibility

Designed as a direct-fit replacement for the ICP / Tempstar / Heil RGS121HSBA0AAAA 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 gas-rated thread sealant.
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
• Stress or gas odor at the manifold-to-valve connection
