619154 Thermocouple, 2Pcs 621737 Thermocouple Interrupter & 622746001 Gas Valve

Thermocouple, Interrupter & Gas Valve Kit

This three-piece service kit bundles 2Pcs 619154 thermocouples, a 621737 thermocouple interrupter, and a 622746001 gas valve so you can refresh the safety and ignition circuit of a gas appliance in one job.

Overview

The 619154 thermocouple, the 621737 thermocouple interrupter, and the 622746001 gas valve work together as a matched set, keeping pilot flame sensing and gas flow shutoff operating as designed. This thermocouple and gas valve kit suits service techs and handy owners repairing a gas heater, fireplace, or similar appliance that will not hold a flame. Every piece swaps in at the original mounting points for a straightforward replacement.

Built For Performance

• Two 619154 thermocouples included so a spare is on hand for the next service call
• 621737 thermocouple interrupter manages the safety circuit signal between thermocouple and valve
• 622746001 gas valve regulates flow and shuts off supply when the flame signal drops
• Threaded thermocouple fittings seat and seal at standard gas appliance connections
• Metal-bodied components built to stand up to continuous pilot heat
• Complete kit covers sensing, interruption, and valve function in one order

On-The-Job Use

• Servicing gas fireplaces and space heaters that lose the pilot flame
• Replacing a failed interrupter during routine appliance maintenance
• Rebuilding the safety circuit on older gas equipment
• Keeping spare thermocouples in a service van for quick callbacks

Specs At A Glance

Good To Know

Q: How do I know which of these parts has failed? A: A pilot that lights but will not stay lit often points to the thermocouple or interrupter, while a valve that will not open or close points to the 622746001. Test each in sequence before replacing.

Q: Can I install this kit myself? A: Gas appliance work carries safety and code requirements, so installation is best handled by a qualified technician unless you are trained for it. Shut off the gas supply before any part of the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
