60 Percent of Heating and Air Conditioning Repair for the Limit Switch
The limit switch, or the safety switch, is a mechanism inside the heating and air conditioning system. Its primary function is to shut off the furnace when it senses a dangerous situation. Typically, the limit switch flips when the furnace or air conditioner overheats. Once the limit switch flips, the furnace will not turn back on until the system is reset. This generally signals for heating and air conditioning repairs.
