Be
a responsible person! One way to be truly responsible homeowner is to
familiarize yourself with the major systems and appliances in your home. By
having some understanding of how, say, your refrigerator or toilet work, you
gain understanding of how to use them efficiently and detect when something
goes wrong. The same is true of your ac unit, which can appear to be a
complicated piece of machinery. In order to help you get acquainted with your air
conditioning unit, we will discuss one of its main control components, the fan
blower control board.
As
the name suggests, fan blower control board is responsible for governing the
operation of the blower in air conditioning unit. At a minimum, a simple fan
blower control board will control the blower igniter, the gas valve and the ac
thermocouple. More complex fan blower control board will also have control over
blowers and/or built-in diagnostic system. To simplify things, you can think of
the fan blower control board as being a driver and the fan blower as its car. Just
as the driver oversees all the functions and operation of the car from ignition
to shutting off the engine likewise the fan blower control board did the same
for the ac unit.
A typical operation sequence for a
fan blower control board goes something like this:
- The fan blower control board receives a signal from the thermostat that the temperature is too low
- It starts the ignition system, whether that be a spark generator, glow coil or pilot light
- Once the igniter is hot, the fan blower control board initiates the flow of cooling gas through blowers
- The fan blower control board keeps the furnace running until it is signaled by the thermostat that the temperature is now high enough, or until it detects something is wrong.
Fan
blower control board is an essential part of your home’s HVAC system. And now,
as a responsible homeowner, you know just how important. If suspect you have a
problem with your furnace, give AC
Parts Distributors a call.
