Lennox 92L15 Limit Switch L160°F-40°F

The Lennox 92L15 is a limit switch which is a safety device that is used in many HVAC appliances such as furnaces, air conditioners and heat pumps. It works as a protective device in that it cuts off the circuit when the temperature goes high, usually between 1600F and 40F in the case of the 92L15. This automatic shutoff helps avoid overheat and possible failure of some of the system’s major components, such as compressors, heat exchangers, and electrical wiring. Controlled by changes in temperature and switching off the circuit in order to avoid further operation, the Lennox 92L15 limit switch is an indispensable component of HVAC devices.
