Lennox 38M69 Limit Switch 322838-753 Precision Calibration: Factory-set for lowThe Lennox 38M69 Limit Switch is a high limit safety component engineered for precision temperature monitoring in commercial and residential HVAC systems. This SPST (Single Pole Single Throw) switch functions as a critical safety barrier, designed to break the electrical circuit and shut down the heating element if temperatures exceed safe operational parameters. Featuring a fixed 240F out (open) and 210F in (close) thermal profile, this bimetal disc
