Lennox 10M62 Control Limit

The Lennox 10M62 Control Limit is a critical OEM safety component designed for high-precision temperature regulation in residential and commercial HVAC systems. This limit switch, also identified by the identical part number 10M6201, functions as a primary thermal safeguard, automatically breaking the electrical circuit to heating elements if internal temperatures exceed the factory-set threshold. Engineers and field technicians rely on the Lennox 10M62 to prevent heat exchanger damage and secondary system failures in popular LGC and LGA series units. Rated as an L200-40F limit control, it ensures the equipment operates within a secure thermal envelope, maintaining narrow differentials for consistent performance. Replacing a drifted or tripped 10M6201 control limit with this genuine Lennox replacement part restores factory-spec safety protocols and prevents nuisance tripping in high-demand environments. This HVAC limit switch is built with a corrosion-resistant metal housing and a high-conductivity internal contact set to withstand the rigorous cycling of modern air handling units.

• OEM Compatibility: Seamlessly replaces legacy 10M6201 and 10M62 units in Lennox LGC060 and LGA036 models.
• Thermal Protection: Prevents critical overheating by disconnecting power at 200°F with a 40°F reset differential.
• System Reliability: Precision-calibrated bimetal disc ensures accurate response times to temperature spikes.
• Durable Construction: Engineered for industrial-grade longevity in high-cycle furnace and air handler applications.

• Is the Lennox 10M62 interchangeable with the 10M6201? Yes, these are functionally identical parts and can be used interchangeably in all supported Lennox equipment.
• What are the symptoms of a failing control limit switch? Common signs include the furnace blower running constantly while the burners remain off, or the system throwing a specific "limit open" fault code on the control board.
• Does this limit switch require a manual reset? No, this is an automatic reset limit (L200-40F), meaning it will close the circuit again once the temperature drops 40°F below the trip point.
