Bard 8402-031 Limit Switch this thermal link interrupts theThe Bard 8402 031 Limit Switch is a critical safety component designed for high limit temperature regulation in Bard HVAC systems and wall mount units. Engineered for precise thermal monitoring, this OEM replacement limit switch features a fixed set point that shuts down the heating circuit when internal temperatures reach 155F (Open), preventing heat exchanger damage and system overheating. Once the unit cools to 130F (Closed), the switch resets the
