Nordyne 626224R Limit Switch

The Nordyne 626224R Limit Switch is a critical safety component designed for high-performance furnace and air handler applications. As a double stack limit switch, this OEM replacement part provides dual-point thermal monitoring, ensuring the system shuts down immediately if internal temperatures at either sensing location exceed safe operating parameters. This Double Stack Limit is the engineered successor and direct replacement for the legacy Nordyne 626224 and 6262240 models, common in Intertherm, Miller, and Nortek gas and electric furnaces. This DPST limit switch features a 160-degree (L160F) trip point, offering robust protection against heat exchanger failure and blower malfunctions. For technicians servicing mobile home furnaces or residential split systems, the Nordyne 626224R provides exact fitment and factory-spec calibration to maintain system integrity and prevent short-cycling caused by airflow restrictions or clogged filtration.

• Dual-Point Detection: The Double Stack Limit design monitors two unique zones, providing a higher level of safety than standard single-point sensors.
• Direct OEM Replacement: Replaces Nordyne 626224 and 6262240 without the need for mounting modifications or terminal rewiring.
• Precise Thermal Response: Factory-calibrated for an L160F opening, ensuring rapid circuit interruption during overheating events.
• System Compatibility: Extensively used across Nortek, Miller, and Intertherm brands for consistent performance in high-static environments.

• Will the Nordyne 626224R fix an 'Open Limit' fault code? If your diagnostic LED indicates an open limit and there is no continuity across the terminals when cool, this replacement limit switch is the required fix.
• Is this part compatible with my electric furnace? Yes, this double stack limit control is frequently utilized in electric furnace heating assemblies to prevent element burnout.
• Does this switch require a manual reset? No, the 626224R is typically an automatic reset control that restores the circuit once the plenum temperature drops below the differential threshold.
