If you notice a small blinking light on your furnace's circuit board, you may wonder what the light means and if it's something you should worry about. Most modern-day furnaces come equipped with a special circuit board and a LED light attached to it. The LED light will blink or flash whenever something bad happens to your furnace. Learn more about the flashing LED light on your furnace and how it can help a repair technician repair your furnace today.
What's the Purpose of a LED Light?
Furnaces can experience numerous problems with their blowers and other equipment over time. LED lights help you and HVAC technicians troubleshoot, find, and fix furnace problems before they get out of hand. If there's a specific problem (or problems) with your furnace, the LED light will alert you by blinking multiple times or in different colors. Sometimes the light will shut off completely.
The code sheet on your furnace's circuit board or door panel should tell you exactly what the flashing light means. But if you're not able to decipher the codes properly, you may not be able to locate the problem with your furnace in a timely manner. You may also cross up or decipher the codes incorrectly. The best way to decode the flashing light on your furnace is to have a heating repair technician do it for you.
How Do You Stop the Blinking LED Light?
Furnace codes can be difficult to decipher without the proper steps. In order to determine why the LED light on your furnace is flashing, a technician will need to do the following things first:
- count the number of times the LED light flashes
- determine the color of the flashing LED light
- decipher the code or codes associated with the flashing LED light
After an HVAC contractor establishes the criteria above, they can repair your heater. The repairs can range anywhere from oiling the blower motor fan to replacing the burners in the combustion chamber. If there's a significant problem with your furnace, such as a broken blower wheel or squirrel cage, a technician may replace it.
A technician can also help you understand and read the codes on your furnace's circuit board. The information can help you repair small problems on your own in the future.
