What Does a Flashing Green Light on Furnace Mean?

Out of sight, out of mind is what applies to most furnaces in Toronto. Typically most homeowners place them in basements to automatically supply heat to the rest parts of the home. However, if you take a look at your furnace, you’ll notice lights blinking. In this post, we’re going to learn about what the green light means, what to do if you see flashing green lights on your furnace, and the consequences of ignoring the green issue. Let’s delve in.

Light Flashing in a Sequence

When the green light is flashing in a sequence, it shows that your furnace has issues that require the attention of a professional. If the light flashes two, five, or six flashes, it means that your unit has exceeded the number of times it requires to start. The feature will prevent your furnace from starting whenever there is a problem. At A Plus Quality, addressing your Heating and Cooling needs, we provide furnace installation Toronto and the GTA so you’ll rest assured that your furnace is offering the comfort you deserve.

Slow Blinking Light

If your furnace displays a green light blinking slowly, it’s a sign that your furnace is on with no request for heat. If you notice a flashing green light on a furnace, then there’s an issue with your IFC circuit board. The solution, in this case, is replacing your circuit board.

What To Do If Your Furnace Has a Green Flashing Light

If you notice a green flashing light, it’s time to call for A-Plus Quality for furnace repair in Toronto. A professional HVAC contractor will inspect the issue and take appropriate steps to repair your furnace to ensure it is working as it should.

Consequences of Ignoring the Flashing Green Light

The circuit board controls the operations of your furnace. It also integrates with AC controls to ensure you achieve maximum indoor comfort. If the green light keeps flashing, it’s more likely you’re going to experience more issues with your comfort. A faulty ICF board can cause excessive noises, or the blower may fail to run.

  • On July 8, 2021, A Plus Quality Inc installed a boiler in my house. The company did a great job. The manager, Shak, came to give me a very detailed estimate. He also followed up every steps. He had a good team to come to do the installation. After installation, they check and explaining to me everything before leaving. I am really impressed. Besides, the office manager, Sandi, was very helpful too. I would like to recommend A Plus Quality Inc to my friends.

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • Why is there ice building up on the copper pipes?
