Modine 5H0673640001 Limit Switch

The Modine 5H0673640001 is a high-limit security component engineered for precise thermal management in commercial heating units and industrial HVAC applications. This 210F CO M/R limit switch (Cut-Off, Manual Reset) is designed to interrupt the electrical circuit when internal plenum temperatures exceed 210°F, providing critical overheat protection to safeguard heat exchangers and surrounding equipment. As the designated direct replacement for 5H67364-1, this OEM component ensures drop-in compatibility and maintains the original safety certification of your Modine unit.

For service technicians performing routine maintenance or emergency repairs, the manual reset functionality is an essential diagnostic feature, requiring a physical inspection of the system before resuming operation. This helps prevent cycling on high limit, which can lead to premature component failure. This HVAC limit control is built to withstand the high-cycle demands of industrial environments, offering reliable temperature monitoring and circuit interruption to ensure system longevity and operational safety.

• Direct OEM Replacement: Engineering-matched for Modine systems, specifically replacing the legacy 5H67364-1 part number.
• Critical Safety Cut-Off: Triggers at a fixed 210°F temperature limit to prevent thermal damage to heating components.
• Manual Reset Feature: Ensures a technician identifies the root cause of overheating before the system is re-energized.
• Rugged Construction: Designed for high-temperature stability and long-term reliability in specialized industrial heating applications.

• Can I use an auto-reset switch to replace this 210F CO M/R limit switch? No. Manual reset switches are safety-critical components; replacing them with auto-reset versions can bypass necessary safety inspections.
• Is the Modine 5H0673640001 compatible with my existing wiring? This part is the direct replacement for 5H67364-1 and typically utilizes standard spade terminals for seamless integration into existing Modine heating units.
• Why is my limit switch tripping frequently? Persistent tripping at 210°F usually indicates restricted airflow, a failing blower motor, or a cracked heat exchanger that must be inspected immediately.
