The HVAC control board is where the thermostat wires connect to the heating and cooling system. In most cases, the control panel can be found on your oven or air handler. I have a Bryant 310AAV gas oven and am trying to locate the control panel. The manual hasn't been very useful in helping me try to locate this.
Is it inside that metal box on the bottom with the big yellow circle? Its control panel serves several purposes in your oven and air handling unit. One of its main functions is to receive information from the thermostat and oven sensors, make decisions based on that data, and then distribute messages to other components of the system. Without a properly functioning control board, items such as the cigarette lighter may never be instructed to ignite. For example, some codes may show a low voltage, which would mean there is a problem with the control board.
The real secret to troubleshooting the control board is that there is no official test to prove that the control board is bad. However, since your HVAC system works almost constantly, you tend to develop occasional problems. For example, the control panel may use data from the flame sensor to prevent the gas valve from remaining open if the igniter has failed.

It is difficult, if not impossible, to tell if a control board is bad if you do not know how the system to which it is connected works. If you can trace a problem with your control board to a faulty transformer or fuse, you can usually replace these individual components to get your oven working again.
The control panel doesn't break that often and it's certainly not the first item you should consider. Many control boards can store error codes when a sensor reports erroneous data or sensor data indicates a possible fault. Given its importance to the proper functioning of your HVAC system, a faulty control board can cause many problems. In these cases, you can usually retrieve the error code by comparing a blinking LED on the control panel with a list of possible errors found in the oven's user manual.
Too often the dashboard is blamed for being the problem when in reality, there is a problem with another component. It is of utmost importance to have a proper solder connection, as this is one of the most common problems when it comes to control boards. When the control board itself fails, it is usually due to an aging component on the board, such as a transistor or relay.
