Function & Application

This thermocouple generates a small electrical signal when heated by the pilot flame. That signal keeps the gas valve open. If the pilot goes out, the thermocouple cools and shuts off gas flow to prevent unsafe conditions.

A failing thermocouple can cause:

• Pilot not staying lit

• Furnace not firing

• Intermittent heating

• Pilot outages during windy or cold conditions

Replacing it restores reliable pilot operation.
