Lennox 51M75 Auto Limit Switch 95°F-125°F

The Lennox 51M75 Auto Limit Switch is an auto-protection device installed in different Lennox HVAC products such as air handlers and furnaces. It also works as a temperature control because the system is protected from high temperatures by a feature that halts the operation of the system if the temperature exceeds a certain level, which ranges from 95°F to 125°F. These help to avoid heating up and even damaging the HVAC systems to the extent that they will require complete replacement.
