Its main function is to detect the pilot flame and allow the gas to flow while it remains lit, ensuring the safe operation of the heating or hot water system. If the thermocouple fails, the boiler shuts off to prevent gas leaks. What problem does this replacement part solve? The boiler does not keep the pilot flame lit. The burner constantly shuts off during operation.
