Description
The Weil McLain 383-900-094 is an OEM replacement flame sensor designed for use with compatible Weil McLain boiler systems. Flame sensors play a critical role in safe burner operation — they detect the presence of a burner flame and send a signal to the ignition control module to confirm combustion. If no flame is detected within the trial-for-ignition period, the control will lock out the burner, preventing unburned fuel from accumulating and creating a hazardous condition.
Key Features
- OEM replacement flame sensor for compatible Weil McLain boiler models
- Ensures accurate flame detection for safe, reliable burner operation
- Helps prevent nuisance lockouts caused by a failed or degraded sensor
- Direct factory replacement for simplified installation
- Supports proper communication with the ignition control module
Application
- Designed for use with compatible Weil McLain boiler systems
- Ideal for service technicians performing routine maintenance or troubleshooting ignition lockout issues
Why Replace Your Flame Sensor?
Over time, flame sensors can accumulate oxidation or carbon buildup on the sensing rod, reducing their ability to accurately detect a flame signal. A weak or failed flame sensor is one of the most common causes of boiler lockout. Replacing the sensor with a genuine Weil McLain part restores proper system function and helps extend the life of your boiler’s ignition system.
