Weil McLain 381-330-026 Ignition Module

The Weil-McLain 381-330-026 Ignition Module is a critical electronic component designed for precise sequence control in high-efficiency gas-fired boilers. As the direct replacement for the 381-330-010, this United Technologies 1013-200 replacement ensures reliable intermittent pilot ignition and flame supervision. Engineered to handle the specific voltage and timing requirements of the Weil-McLain CG boilers, this module manages the gas valve, pilot flame sensing, and main burner ignition cycles. For technicians troubleshooting ignition failure or erratic flame signals, upgrading to this current OEM specification eliminates compatibility issues inherent in older revisions. The 381-330-026 ignition control is built to withstand the thermal cycling typical of commercial and residential hydronic systems, providing consistent direct spark ignition (DSI) or pilot control protocols. Utilizing high-grade circuitry for accurate flame rectification, it ensures the system shuts down safely if a flame is not detected, meeting stringent safety standards for modern HVACR applications.

• Seamless Compatibility: Serves as the factory-authorized update for the discontinued 381-330-010 module.
• Precise Flame Sensing: Advanced flame rectification technology prevents nuisance lockouts and ensures safe burner operation.
• Durable Construction: Built by United Technologies to OEM specs for long-term reliability in high-heat environments.
• Simplified Installation: Standard wiring terminals allow for quick field replacement, reducing labor time on site.

Is the 381-330-026 a drop-in replacement for the 381-330-010?

Yes, the 381-330-026 is the current OEM replacement. It follows the same wiring logic and mounting footprint as the older 010 version, making it a direct swap for field repairs.

What are the symptoms of a failing Weil-McLain ignition module?

Technicians usually identify failure through a lack of power to the gas valve, failure to generate a spark during the ignition sequence, or intermittent lockouts despite a clean flame sensor and proper grounding.

Does this module work with both propane and natural gas systems?

Yes, the module is designed to control the ignition sequence regardless of the gas type, provided the boiler is properly jetted for the fuel being used.
