Description

This thermocouple is a flame-sensing safety device for gas ranges and ovens that helps confirm the pilot or burner flame is present so the appliance can operate safely. It replaces a worn or faulty sensor to restore reliable flame detection. What it does:

• Detects the presence of a pilot or burner flame and signals the gas valve to stay open
• Commonly used in gas ovens and ranges as the flame safety sensor
• May be replaced if appliance won't light, flame won't stay lit, or oven/burner won't heat reliably
• Works as part of the gas safety system to help prevent unlit gas flow

What's included:

• One thermocouple flame sensor

Install notes:

• Disconnect power and turn off the gas supply before starting any service
• Handle fittings carefully; do not kink or excessively bend the sensor probe
• Tighten gas connections to manufacturer torque specs and test for leaks after installation
