Lennox 44L65 Limit Switch R-22 ensuring the diaphragm and snap-actingThe Lennox 44L65 Limit Switch is a critical safety component designed for precise thermal regulation within residential gas furnaces and air handlers. Engineered as a 160 185F AUTO limit switch, this normally closed (NC) thermal sensor monitors heat exchanger temperatures to prevent overheating and potential component failure. Functioning as a high limit safety cut out, the 44L65 features an automatic reset mechanism that restores the circuit once
