Lochinvar & A.O. Smith 100108267 Thermocouple

Service professionals know that a failing pilot signal is a common cause of residential water heater lockout. The Lochinvar & A.O. Smith 100108267 Thermocouple is a direct replacement 24 inch thermocouple designed to restore the millivolt signal required for gas valve operation. Built for heavy-duty cycle performance, this OEM water heater part delivers a consistent 30mV output, ensuring the pilot flame presence is accurately communicated to the control system. When you are troubleshooting LTL07575 water heater repairs, using a genuine A.O. Smith 100108267 part eliminates the common seat-depth issues found with generic 19-24 inch lead kits. This replacement thermocouple is engineered to fit Lochinvar LTL residential models and various standard power-vent or atmospheric units. Its 24-inch length provides ample reach for clean routing through the combustion chamber, preventing heat stress on the lead wire while maintaining a secure connection to the gas control valve.

• 30mV Power Output: Provides a stable millivolt signal to the gas valve, preventing nuisance shutdowns.
• OEM Compatibility: Specifically designed for Lochinvar and A.O. Smith commercial-grade residential units.
• Direct Cross-Reference: Replaces legacy part numbers including 9000056015 and 1980-024.
• Durable 24" Lead: Allows for versatile installation in large combustion chambers without stressing the wire.

What are the symptoms of a bad 100108267 thermocouple?
If the pilot light ignites but goes out immediately after releasing the control knob, the thermocouple is likely failing to generate the necessary voltage to hold the solenoid open.

Can I use this on a model other than LTL07575?
Yes, this 100108267 thermocouple is compatible with numerous Lochinvar and A.O. Smith residential water heaters, though the 24-inch length should be verified against your specific cabinet dimensions.

Does this kit include the mounting nut?
This is an OEM thermocouple assembly that typically includes the standard threaded connector for secure gas valve attachment.
