The Hobart 11335 Coaxial Thermopile 36″ 250-750 MV is a flame-sensing component used in gas-powered commercial cooking equipment to support proper ignition and burner control. Installed in the pilot or burner assembly, it generates a small electrical voltage when heated by the pilot flame; this signal is used by the appliance’s control system to confirm flame presence and allow the gas valve to stay open during normal operation. By converting heat into a measurable electrical output, the thermopile helps prevent unlit gas flow and contributes to consistent burner performance. It is common in grills, fryers, and similar appliances where accurate flame detection is required.
