Weil McLain 382-200-375 Switch Kit

The Weil McLain 382-200-375 Block Temperature Switch Kit is a critical safety component designed for precise thermal monitoring in GV90+ and GV series boilers. As a veteran-grade OEM replacement part, this kit ensures the heat exchanger block operates within safe parameters, preventing catastrophic equipment failure due to localized overheating. The block temperature limit switch is engineered with a calibrated 350°F open and 250°F close setpoint, providing a reliable electrical interrupt when thermal limits are reached. This kit includes the snap-action switch and the necessary mounting bracket to maintain direct contact with the boiler block for accurate sensing.

For service technicians, installing this genuine Weil McLain kit is a standard procedure when troubleshooting boiler lockout codes or intermittent shut-offs. Proper seating of the bracket is essential to ensure responsive heat transfer and to avoid nuisance tripping. Integrating this HVAC high-limit control into the burner circuit maintains system integrity and complies with factory safety specifications for high-efficiency hydronic systems. When diagnosing Weil McLain boiler troubleshooting issues, verifying the continuity and setpoints of the block switch ensures the boiler safety controls are functioning at peak reliability.

• Precise Thermal Protection: Features a fixed 350°F open / 250°F close threshold for reliable overheat prevention.
• Application Specific: Optimized for seamless compatibility with GV90+ and GV series gas boilers.
• Complete Installation Kit: Includes the block switch and heavy-duty mounting bracket for secure placement.
• OEM Standards: Manufactured to original specifications to ensure proper electrical rating and mechanical fit.

• How do I know if my block temperature switch is faulty? Technicians should check for continuity across the switch terminals during a call for heat; if the switch remains open at room temperature or fails to reset at 250°F, replacement is required.
• Will this kit fix a flashing light lockout on my GV90+ boiler? A failing block switch is a frequent cause of safety lockouts; once the heat exchanger reaches the 350°F limit, the switch interrupts the control circuit until the system cools.
• Is the mounting bracket mandatory for installation? Yes, the bracket ensures the sensor maintains the necessary surface tension against the block for accurate temperature detection.
