Description

This thermocouple is a replacement flame-sensing probe that detects the burner/pilot flame so the gas valve operates correctly, helping restore reliable ignition and safer operation for compatible gas ovens and ranges. What it does:

• Senses presence of the burner/pilot flame and signals the gas valve to stay open.
• Stops gas flow when a flame is not detected, helping prevent unburned gas buildup.
• Replaces a failed probe that can cause the oven or range not to light or the flame to go out unexpectedly.
• Resolves intermittent ignition or no-heat symptoms related to a faulty flame sensor.

What's included: Includes: one thermocouple probe. Install notes:

• Turn off both the gas supply and electrical power before starting work.
• Verify correct probe orientation and secure connections; do not bend or kink the sensor.
• Tighten fittings to manufacturer torque; avoid overtightening which can damage the probe.
• After installation, check gas connections for leaks and test ignition.
