Customer Questions and Answers for Orifice Holder (G4) by Whirlpool

This G4 orifice holder mounts beneath the cooktop to secure the burner orifice and route gas from the valve to the burner head. Replacing a damaged holder helps restore proper gas flow and consistent burner performance.

• Holds and aligns the orifice for the G4-designated surface burner
• Channels metered gas from the valve to the burner head
• Supports stable, even flame and reliable ignition at that burner
• A worn, cracked, or stripped holder may cause weak/uneven flame, delayed ignition, or a gas odor near the burner

• Disconnect power and shut off the gas supply before servicing; allow the appliance to cool
• Remove burner caps/heads and access the holder
• Transfer the existing orifice spud if reusing, or install the correct orifice specified for your gas type
• Tighten fittings to spec and leak-test all gas connections with an approved solution before restoring service
