Description
The Weil McLain 383-600-300 is an OEM replacement flame sensor kit designed for use with compatible Weil McLain boilers. This complete kit includes the flame sensor, gasket set (GSKTS), and mounting screws — everything needed for a straightforward, leak-free installation right out of the box.
The flame sensor is a critical safety component in your boiler’s burner control system. It detects the presence of a burner flame and sends a signal to the ignition control module to confirm ignition. If the sensor fails or becomes contaminated, the control board will shut down the burner as a safety precaution, resulting in a no-heat condition. Replacing a worn or faulty sensor with a genuine Weil McLain part restores proper flame detection and reliable boiler operation.
