Control Boards for HVAC Equipment

What is HVAC control board?

 Heating, ventilation and air conditioning (HVAC) control panels are systems that manage the temperature and air in a given environment. They are suitable for commercial, residential, public or industrial usage. the control board to act as the brains of the  HVAC with the electric ignition or the air filter. Your control board serves several purposes in your furnace and air handler unit. One of its primary functions is to receive input from your thermostat and furnace sensors, make decisions based on that data, and then distribute messages to other components in the system. Without a properly functioning control board, elements such as your igniter may never receive instructions to turn on.The control board is more than just a dumb relay, however. Furnace manufacturers design modern control boards to monitor sensor input for signs of trouble. This role helps your furnace to operate safely. For example, the control board can use data from the flame sensor to prevent your gas valve from remaining open if the igniter has failed.

Where is the hvac control board

The HVAC control board is where the thermostat wires connect to your heating and cooling system. In most cases the control board can be found at your furnace or air handler. If you’re unable to locate your HVAC control board or are uncomfortable doing so, please contact a certified HVAC technician in your area for additional assistance. 

What causes HVAC control board failure?and How do I know if my HVAC control board is bad?

Given its importance to the proper functioning of your HVAC system, a faulty control board can lead to many issues. If your control board is not receiving power or it fails to properly output power, then your furnace may not function at all. A faulty control board can also lead to issues at your thermostats.
In some cases, problems that seem to originate with the control board are power faults. If the furnace's transformer fails, then it may not output the correct voltage to the transformer. Without 24V power at the control board, your furnace will not function. Likewise, your furnace includes a fuse to protect the igniter and blower motor. If this fuse blows, then your igniter and blower will not operate.
When the control board itself fails, it's typically due to an aging component on the board, such as a transistor or relay. Although these components can withstand relatively high temperatures, years of heating and cooling cycles can wear them out. Issues with your home's electrical wiring or even a clogged filter can sometimes result in excessive wear on control board components.

How to Repaire a Faulty Control Board

If you can track a problem with your control board down to a faulty transformer or fuse, then you can usually replace these individual components to get your furnace working again. When the failure is on the control board, replacing the whole board is typically the only option. Since you will be dealing with delicate wires and household voltage, you should trust this work to an HVAC professional.

How much does it cost to replace an AC control board?

Each part has a special place in your system, and your control board is the brains of the operation. So when you’re looking for the right candidate for the job, don’t skimp on the details: you’ll want to choose the best control board for your unit. However, each HVAC unit is different, which means the cost can vary — the part itself often costs somewhere between $150 and $500 dollars.
