Some Reasons Why a High-Efficiency Furnace Keeps Stopping




Understanding Your High Efficiency Furnace

Having a high-efficiency furnace is the ideal way to keep your home warm during cold Kansas winters. But while these popular high-efficiency furnaces are reliable systems, problems can still happen. One of the problems that can happen is when a high efficiency main burner shuts off shorting after ignition.

A high-efficiency furnace has an AFUE rating of 90 or higher. That AFUE number means that these heaters can convert at least 90% of the energy it uses to run into heat that disperses through your house.

Furnace Burners 101

Furnace burners are a main component to the combustion process within your furnace. Their job is to ignite and burn the fuel (which is usually natural gas or propane) to generate heat. Burners are inside the combustion chamber of your furnace. This is where air and fuel mix, ignite, and create the heated air that circulates through your home.

You will have either a single or dual burner. Which one you have will depend on how big your furnace is.

There are several types of burners. More modern, high-efficiency furnaces typically have an Inshot Burner that has a blower which moves air through the ignition chamber and heat exchanger.

The Role of Furnace Burners in High-Efficiency Furnaces

High-efficiency furnaces are designed to maximize the amount of heat generated from the fuel while minimizing waste. Furnace burners play a crucial role in achieving this goal. Here’s how:

  1. Many high-efficiency furnaces are equipped with condensing technology. This means that they recover and utilize the heat from the combustion process more effectively. The burner’s design is optimized to create a hotter flame, which results in more efficient heat transfer.
  2. Some high-efficiency furnaces feature modulating burners. Instead of running at full blast and then shutting off, modulating burners can operate at varying levels of intensity, ensuring a more consistent and efficient heating experience.
  3. Advanced burners are often used in zoned heating systems. The precise control offered by these burners ensures that you only heat the areas you need, further improving efficiency.


Furnace Burners at Work

  1. First your HVAC system will detect there is need for heating up the air once the temperature is lower than the desired setting on your thermostat.
  2. Then the combustion process starts. A fuel valve opens which releases fuel for the furnace burner. At the same time, the air intake system is allowing fresh air to come in.
  3. Next your heater’s ignition system ignites the fuel-air mixture and creates a controlled flame. While older furnaces may use a pilot light, nearly all modern furnaces use electronic ignition.
  4. Now the burner is lit. Warm air will blow throughout your home’s ductwork and out your vents. Your furnace will run continuously to reach the thermostat temperature setting.

Problems with Older Furnace Burners

Since it is regularly exposed to high temperatures, an older burner is more prone to cracking.

Another issue with burners on older furnaces is rust and deterioration. This problem can be prevented by having professional maintenance done regularly on your home heating system.

A professional HVAC technician will ensure your furnace is clean and will be able to identify signs of aging or wear. They can often replace damaged parts before they cause bigger problems that can cause a heating system to entirely break down.
