ICP Gas Valve Support Bracket for RGS120STAA0AAA | OEM 1178238 | Ships Today

Overview

This is the OEM gas valve support bracket (part number 1178238) for the ICP/Tempstar/Heil RGS120STAA0AAA gas furnace. The bracket secures the gas valve to the burner assembly, holding it in correct alignment with the manifold and burner orifices so the gas-air mixture stays consistent. A cracked, corroded, or missing bracket lets the gas valve sag or vibrate, which can stress the manifold connection, cause noisy operation, or misalign the burners. Replacing a failed bracket with the exact OEM part restores a secure, factory-correct mount.

Compatibility

Engineered for the ICP Tempstar Heil RGS120STAA0AAA gas furnace. Verify the part number against your existing bracket before ordering, as bracket geometry varies across furnace platforms.
