An HVAC control board is an intricate system that ensures your home’s heating and cooling system is operating properly and efficiently. This control board is one of the essential systems in a modern home and is crucial to your comfort. Indeed, this board is the heart of your heating and cooling system. However, many homeowners do not fully comprehend how and what an HVAC control board does. Thus, knowledge about this device will help you repair and use it in the coming years. So here are some things you should be aware of regarding your HVAC control board.

What Is an HVAC Control Board?

The HVAC control board is an electronic device that serves as the brain of your home’s climate control system. It monitors and regulates temperature sensors around the house. It also sends signals to your thermostats, fan speed controls, and air handler controls. Altogether, it runs the whole show to provide reliable, consistent heating and cooling from your furnace or AC unit. In most cases, you can find the control board on the furnace or the air handler. Sadly, like many other components of your HVAC system, the control board will also experience failure at some point.

Recognizing the Common Signs of a Failing HVAC Control Board

Overall, control boards perform very well. Have you been using your HVAC unit for a while and noticed a gradual decline in performance in some aspects? It may be time to pay closer attention to your control board. Our team of HVAC professionals at Pioneers Heating and Air listed the most common indications where a control board needs troubleshooting.

Blinking Lights

LED lights are usually indicators of a problem with the operation of your HVAC systems. The LED lights on your unit will typically blink in different patterns when something is wrong with your system. 

You can look up error codes in your user’s manual to help you identify the issue. These codes will clearly show which part of the machine is not functioning right, such as the control board. That is critical information for an HVAC repair company to know when determining where to begin diagnosing your problem.

Temperature Fluctuation

Inconsistent airflow is another indication that the control board needs to be replaced. If certain areas of your home are consistently colder or warmer than others, inspect the vents or radiators to see if they are working properly. 

Thermostats should register temperature changes continuously. However, if your thermostat is not functioning right, it could result in broken vents or radiators. If this is the case, you should immediately contact Pioneers Heating and Air for heating or air conditioning service.

Irregularities in Operation Sequence

The sequence in which your HVAC system operates is critical as it defines how efficiently the equipment works. Have you noticed anything unusual while your unit is in use? A discrepancy between what you see and what should happen before it could indicate a control board issue. 

The blower staying on, the ignition remaining locked on, or gas jets not activating when they should indicate a problem with the control board. Call a professional for HVAC repair to address any issues before they become too serious!
