Lennox 93J39 Limit Switch Designed to deliver 15KV toThe Lennox 93J39 limit switch is a critical safety component designed for precise thermal management in high efficiency HVAC systems. This 210F CO auto limit switch acts as a primary safety boundary, effectively breaking the electrical circuit when the heat exchanger plenum reaches the designated 210 degree Fahrenheit threshold. Engineered for seamless field replacement, the 93J39 is identical to 93J3901, ensuring zero latency compatibility for
