Thermocouple Function in Pilot Light Systems
The thermocouple is a critical component that ensures the pilot light remains lit. It generates a small electrical current that keeps the gas valve open. If the thermocouple is dirty or faulty, it may not detect the flame, causing the gas valve to close.
-
Signs of a faulty thermocouple include inconsistent flame or frequent pilot outages.
-
Cleaning can often resolve minor issues, but replacement is necessary for severe damage.
