ICP Gas Valve Support Bracket for RGS121LRCB0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Heil / Tempstar RGS121LRCB0AAA gas furnace. The bracket secures the gas valve to the furnace burner assembly, holding it in the correct position and maintaining proper alignment between the manifold, burners, and valve body. A cracked, corroded, or missing bracket can let the gas valve shift, stress the manifold pipe threads, and create vibration or rattle during operation. Replacing damaged mounting hardware restores a secure, leak-resistant gas train.

Specifications

Compatibility

Designed for the ICP-family RGS121LRCB0AAA furnace and other models in the RGS gas-furnace line that share the same burner/valve assembly. Always confirm your model and serial range before ordering.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the gas valve, bracket, and manifold position before removing anything.
4. Remove — Support the gas valve, then unfasten the old bracket from the valve body and furnace frame.
5. Install — Mount the new bracket, reattach the gas valve, and torque fasteners so the valve sits square to the manifold.
6. Test — Restore gas and power, then leak-check all joints with soap solution and verify normal ignition.

Signs You Need a Replacement

• Visible cracks, rust, or distortion on the existing bracket
• Gas valve that wobbles or shifts when touched
