This 7-inch furnace high limit switch is a vital safety component designed for residential HVAC systems and gas furnaces. Functioning as a high limit control, this sensor monitors the temperature within the heat exchanger to prevent overheating. If the furnace reach an unsafe temperature, the switch automatically opens the electrical circuit to shut down the heating element or gas valve, protecting the appliance from damage and ensuring home safety. Featuring an auto-reset design, the switch will automatically close and restore operation once the internal temperature drops by 30 degrees Fahrenheit. This part is a common solution for furnaces that are short-cycling or failing to maintain a consistent heating cycle.
