Weil McLain 382-200-375 Switch Kit Furnace limit switches are safety-critical

Furnace limit switches are safety-critical components calibrated to the specific thermal limits of the heat exchanger

and 120V lighting circuits

ensuring a wide temperature operating range from -20°F to 450°F

While the formula is non-corrosive

This high-temperature limit switch ensures that if the heat exchanger encounters downstream pressure issues or combustion air disruptions

Weil McLain 382-200-375 Switch Kit Furnace limit switches are safety-criticalThe 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 350F open and 250F close setpoint,
