Description
The Lennox 26H66 is an automatic limit switch, which is a safety device used in many Lennox HVAC equipment such as furnaces and air handlers. It survives as a security shut-off by reducing electric current and can be established in this case to range between 145°F and 175°F. Such a shutoff is useful to avoid the overheating of the systems such as the compressors or heat exchangers and other components. Apart from protecting the equipment from overheating and subsequent failure, the Lennox automatic limit switch is a safety measure that comes in practical when ensuring that your heating and cooling lasts longer than intended.
