Lennox 86H72 Limit Switch 160°F-190°F

The Lennox 86H72 160-190F Limit Switch is a safety device used on HVAC systems, more so in furnaces and heating units. This limit switch ensures that the temperature in the system does not go high which is harmful. If the temperature rises beyond this set temperature range of 160-190°F, the switch turns off the system immediately to prevent high temperature and perhaps damaged equipment. The 86H72 Limit Switch utilized in Lennox furnaces and other heating apparatuses ensures the secure working system by not allowing high heat to set a fire or damage equipment.
