Limit Switches

High-limit furnace switches are installed on furnaces to avoid dangerous or catastrophic situations. Your home furnace combines the use of burning gas under pressure and a circulation fan that forces the warm air through the residence. If the heat generated by the combustion of fuel cannot circulate due to system failure, the temperature can rise to a potentially dangerous level and result in a fire. The high temperature limit switch will sense this and shut off the combustion components.
