Technology pervades every aspect of human life now. In fact, you might be surprised at just how many things have a little bit of technology in them. Take your home's furnace or heating appliance, for example. It does not matter what kind of heating appliance you have; it has some technology built into it. Almost every home heating appliance contains a circuit board now. Here is what those circuit boards are doing in there, and why you may eventually need them replaced or fixed. 

The Circuit Board's Role in Modern Heating Appliances

If you were to pop open the control panel on any modern heating appliance, you would spot the circuit board almost immediately. It is unmistakable in appearance, looking very much like it belongs in a computer rather than in your furnace or boiler. However, the circuit board plays a major role in how your heating appliance is able to keep your home toasty. 

The thermostat in the house sends electrical signals to the circuit board in your heating appliance. The circuit board interprets those signals and then sends its own signal to the fuel burner or electrical heating coil and ignition button. The signals sent by the circuit board tell the other parts of the furnace that A) you want the heat to be working, and B) you want the heater to heat your home to a specified temperature on the thermostat. The heater complies until the thermostat registers that your home is sufficiently heated to the correct and requested temperature. 

Why You Might Need the Board Fixed or Replaced in the Future

Because of its vital role in starting the heater/furnace/boiler, the circuit board is one component that will cause the entire system to fail if the circuit board does not work. You will lose heat, and no new heat will be generated during the time that the circuit board is not working. An HVAC technician supplying heating services to your residence or business will need to get in there and check the circuit board.

It could be something as simple as a disconnected wire or something as complex as a fried circuit board. The former issue only requires a little solder and a few minutes. The latter requires a complete replacement of the circuit board, which the technician may or may not have on hand. It may take a couple of hours to complete a full circuit board replacement.
