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.

FAQ

  • What are mini-split advantages?

    Just as the name implies, a “mini-split” system is a “split system” however available in smaller capacities, for single room to whole house conditioning. Mini-split systems may range from as small as 9,000 BTUh per hour, comparable to say, a small window AC unit, for individual room use, up to 4 and 5 ton capacities for “Room By Room” (also known as “Zoning”) and whole house conditioning. With near universal design, mini-splits are “heat pumps” which provide both heating and cooling for a home. Here are key advantages when compared to traditional split systems:

    Efficiency- Mini-splits are highly engineered systems which offer attractive operating efficiencies, in many instances, eligible for utility company rebates.
    Heat Pump- Most mini-split systems are heat pumps, providing year-round comfort.
    Solar friendly- Due to very low power requirements, mini-splits are an ideal complement to “Net Zero Energy” homes, or any home using renewable power.
    Carbon footprint- Mini-splits are 100% electric, with zero operating emissions of any type.
    Zoning- Most mini-split manufacturers offer systems capable of room-by-room “zoning”, to account for peak demands of a room based upon construction type, exposure orientation and usage.
    Variable capacity- Mini-splits are typically DC inverter driven. That is, a variable speed compressor which modulates in proportion to instantaneous demand. Most conventional split systems, by comparison, operate with an ON-OFF strategy. (Would you use an ON-OFF switch as the accelerator in your vehicle?)
    Location, Location, Location!- Mini-split outdoor units are compact; they can be located far away from noise-sensitive areas, such as bedrooms and home offices. Mini-split indoor units have the ability to be installed where conventional systems cannot.
    They’re perfect for additions and remodels where access to current HVAC system is difficult to access.
    Modern mini-split systems are remarkably quiet; in fact, many times their operation is unnoticed by the end user.

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

    There can be many reasons why the refrigerant pipes are freezing up but the most common issue is low refrigerant levels. If your AC unit has ice buildup turn off the unit for at least 4 hours and call us at 416-410-0337

  • How do I know what size unit I need?
    If you have any problems with your system, you should contact the contractor who installed the units. All our systems are covered by a 5 year parts, 7 year compressor limited warranty
     
  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.
