Lennox 36M62 Limit Switch
The Lennox 36M62 Limit Switch is a high-limit safety component engineered for precision thermal monitoring in residential and light commercial furnace repair applications. This OEM Lennox limit switch is factory-calibrated to a 150°F cut-out temperature, functioning as a critical manual-reset high limit switch to prevent heat exchanger damage or unsafe operating conditions. With a fixed 40°F reset point, the 36M62 ensures the burner circuit is interrupted immediately if the internal plenum temperature exceeds safe parameters. This HVAC replacement part is built with a standard snap-disc surface mount for rapid response to thermal fluctuations. When diagnosing a furnace not heating or a system that trips before completing a cycle, replacing a fatigued or failed limit switch with this genuine Lennox 36M62 150-40 maintains the original safety logic of your HVAC system.
Key Benefits:- Critical Safety Protection: Protects against overheating by interrupting power to the burner at 150°F.
- Manual Reset Function: Requires technician intervention after a trip, ensuring a thorough system inspection.
- Broad Compatibility: Serves as a direct replacement for part numbers 36M6201, 20054605, and R20001108.
- OEM Reliability: Designed to meet exact specifications for Lennox, Armstrong, and Ducane heating units.
- What causes the 36M62 limit switch to trip? Typically, restricted airflow from a dirty filter, failing blower motor, or blocked ductwork causes the plenum to overheat.
- Is the Lennox 36M62 an automatic or manual reset? This specific model is a manual-reset switch, requiring the red button to be depressed once the temperature drops below 40°F.
- How do I verify if this limit switch is bad? Use a multimeter to check for continuity across the terminals; if the switch is open while the furnace is cool, it needs replacement.
