Typical Wiring Diagram For Oil Fired Forced Air Furnace

By | August 14, 2022



As the weather starts to cool, many people across the country start to think about their home's heating system. Oil fired forced air furnaces are a popular and efficient way to keep homes warm in the winter months. For those who are unfamiliar with this type of furnace, understanding the typical wiring diagram is essential for operating it safely and correctly.

The wiring diagram for an oil fired forced air furnace is fairly straightforward. It consists of three main components: the power supply, the control board, and the thermostat. The power supply is typically connected to the furnace's main panel, while the control board and thermostat are connected to the furnace itself. Once the power supply, control board, and thermostat are connected, the furnace will be ready to operate.

The control board is responsible for controlling when the furnace turns on and off. The thermostat is responsible for controlling the temperature of the furnace. When the thermostat detects that the temperature has dropped below the desired setting, it sends a signal to the control board, which then turns on the furnace. The furnace will then run until the desired temperature is reached, at which point the control board will turn off the furnace.

Understanding the typical wiring diagram for an oil fired forced air furnace is essential for ensuring that it is operated correctly and safely. With the right information, users can easily install, maintain, and repair their furnace, all while keeping their home warm throughout the winter months.
