Robertshaw HVAC Thermal Coupling - 1970-024

Restore reliable pilot flame sensing with this Robertshaw HVAC Thermal Coupling - 1970-024. This thermocouple sits in the pilot flame and generates the signal needed to keep the gas valve open during normal operation.

1970-024 is a gas-appliance thermocouple chosen by length, tip style, and connection size. It is commonly replaced when the pilot lights but will not stay lit or when the original sensing tube is worn, kinked, or heat-damaged.

Compatibility: Match this service part by the exact gas-appliance application, fuel type, control style, dimensions, and connector configuration.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Pilot flame will not stay lit, intermittent burner operation, or repeated relighting.
• Visible/Sensory Cues: Burned tip, kinked tube, loose connection, or visible corrosion around the thermocouple and pilot area.

Pro Tip: Do not overtighten the gas-valve connection. Route the replacement thermocouple the same way as the original so it stays fully in the pilot flame.
