The indicator LED is a small light that provides visual status information for your boiler or burner system. Whether it signals power, operation, or fault conditions, a working LED is important for monitoring system health. If the original LED burns out or becomes dim, replacing it restores clear indication and helps with troubleshooting. This component is a common spare part for heating equipment, easy to install and compatible with many control panels.
