For some, that first time you turn your furnace on for the season can have you holding your breath. No one wants to have problems with their furnace. However, there are a number of things that can go wrong when it comes to the furnace in your home. One part of your furnace that is integral to it working and functioning properly is the control board. If this part isn’t working, there are going to be a host of issues that you run into. Ambient Heating & Air Conditioning is here to talk about the control board and explain what control board issues might look like.
What is the HVAC Control Board?
If you don’t have much experience with furnaces, you may not know what the control board looks like or even does in your system. The control board is just what it sounds like; it is the part that is the brain of your furnace. It tells all the parts when they come on and for how long. It is filled with fuses and wires that plug into it and is essential to your furnace operation.
How Do You Diagnose HVAC Control Board Failure?
When there are problems with your control board, you will more than likely know it. The control board isn’t a part that frequently goes out on people, but you can definitely have problems with it. Usually, if the control board isn’t working, it is because it sustained damage somehow. For instance, if there was water on the unit during the summer months because the condensate drain wasn’t working properly, it can easily cause damage that you wouldn’t realize what there until you turned your furnace on for the winter. Here’s some signs that there is an issue with your control board.
– Indoor Discomfort: The control board tells your furnace when to stay on and for how long. If this part is malfunctioning, you will more than likely have uneven temperatures. You may find that sometimes your home gets too hot while other times it isn’t getting warm enough.
– Furnace Lights Blinking: There are lights on furnaces that tell you when there is a problem that needs to be addressed. If you are having an issue with your control board, you will more than likely see some indicator lights that are letting you know that someone needs to look at the system.
– Interruption of Furnace Operation: Your furnace turns on in a sequence of events. When the sequence is thrown off, you will more than likely know it because the furnace will sound different. It may try to start up over and over again or there may be parts that are turning on when they shouldn’t. If you notice that it isn’t sounding normal, turn it off and call the pros.
