619154 621737 622746001 Thermocouple & Gas Valve 2Pcs Replacement Kit

Product Overview

This aftermarket replacement thermocouple set includes two 619154 thermocouples, a 621737 thermocouple interrupter, and a 622746001 gas valve. A thermocouple generates a small voltage when heated so a gas control system can sense whether a pilot flame is present, while the interrupter works with that signal and the gas valve controls gas flow to the burner. The supplied part numbers 619154, 621737, and 622746001 are provided for reference when matching existing components.

Key Features & Performance

• Thermocouples sense flame presence and provide a small signal to the gas control system so it can determine whether the pilot is lit.
• A thermocouple interrupter works within the safety circuit to interrupt the gas supply when the flame signal is lost.
• The gas valve regulates the flow of gas to the burner in response to the control system.
• Cross-references part numbers 619154, 621737, and 622746001 for comparison with the numbers on the existing components.
• Sold as a set with two thermocouples, one interrupter, and one gas valve as named in the title.

Common Uses

• Replacing a worn, damaged, or malfunctioning thermocouple, interrupter, or gas valve in a gas appliance.
• Servicing the flame-sensing and gas control circuit during routine maintenance or repair.
• Restoring normal gas control function after the original components have failed.

Frequently Asked Questions

Q: What does a thermocouple do in a gas appliance? A: A thermocouple generates a small voltage when it is heated by a pilot flame, and the gas control system uses that signal to determine whether the flame is present and to keep the gas supply open.

Q: How should fitment be verified? A: Compare the complete part numbers on the existing components, including 619154, 621737, and 622746001, and confirm they match the numbers on the replacement parts before purchase.
