  • Thermostat

    The thermostat enables you to set the air temperature in your house. When you adjust the temperature on the thermostat, it signals the control board in the furnace to initiate the heating process. This is done by activating the ignition switch.

  • Ignition Switch

    The ignition switch acts as the "trigger" to ignite the gas in the combustion chamber of your furnace. The gas is then fed into the chamber through gas jets. An older furnace will have a pilot light to ignite the gas jets, while newer furnaces have a hot surface ignitor for the same purpose.

  • Gas Valve

    Once the temperature in your home has reached the setting indicated on the thermostat, the thermostat will close the gas valve, thereby stopping the supply of warm air into the house.

    The furnace's gas valve controls the opens and closes, which allows gas to flow to the pilot light and burner(s). While the component itself if actually rather simple, this function makes the gas valve is a crucial part of your furnace.

The procedure will start again once you raise the temperature of the thermostat or the temperature in your house plummets too low and the heater activates to bring back the correct temperature based on the thermostat settings.

For your residence to be appropriately warmed, all the components in your furnace must be functioning correctly. Any single malfunctioning piece can lead to problem. Poor air circulation, blowing of cold air, and other issues are often the cause of service calls to Leonard Splaine & Co.
