Description
The York S1-025-41319-000 A/R Limit Switch is a design of a temperature-controlled secure regulator used in HVAC systems to check internal heat and control blower or burner circuit. It operates on a system of opening its electric contact at 165°F and closing it at 125°F to turn off power when the temperature is too high and reconnect it when temperatures fall back to normal. It is mounted in the air handler close to the part of the furnace that generate heat to minimise overheating and aid in controlled operation in HVAC systems.
