This thermopile is used in commercial gas cooking equipment to generate electrical power from a pilot flame. The 24-inch assembly has a two-lead design with spade terminals and is made for two-screw mounting applications. It works with compatible gas valves and pilot systems in fryers, griddles, and other commercial kitchen equipment. Thermopiles are commonly found in restaurants, concession equipment, and commercial foodservice kitchens using standing pilot systems. The component helps keep the gas valve open while the pilot flame is active. If the thermopile becomes weak or damaged, the pilot may not stay lit, or the burners may not operate correctly. Replacing the thermopile can help restore normal heating and ignition function.

Equipment Compatibility:
Commonly used in Avantco commercial gas fryers, griddles, and pilot-operated cooking equipment. This 24" Thermopile 2-Lead 177400043 is compatible with equipment from brands such as American Range, APW Wyott, and Avantco, where pilot flame power is used for gas valve operation.

Brand Compatibility:
Replaces multiple part numbers across various commercial gas cooking equipment brands, including American Range, APW Wyott, and Avantco. Refer to the “Replaces Parts” section for complete cross-reference details.
