Malfunctioning Burners in Your Furnace
Posted On: December 6, 2024
Your furnace's burners are critical components that ensure proper heating in your home. When they malfunction, your comfort and safety can be at risk. Let’s explore what causes burner issues, how to identify them, and what you can do to address the problem.
Common Causes of Malfunctioning Burners
- Dirt and Debris Buildup: Over time, dust and grime can clog burners, preventing them from igniting or burning cleanly.
- Faulty Ignition System: A broken ignitor or pilot light failure can prevent burners from lighting.
- Gas Flow Issues: Problems with the gas valve or a disrupted supply can lead to uneven or non-functioning burners.
- Corroded or Damaged Components: Rust or wear on burners or their surrounding parts can impair performance.
Signs Your Furnace Burners Are Malfunctioning
- Delayed Ignition: A loud bang or delay when your furnace starts could indicate gas buildup caused by burner issues.
- Yellow or Flickering Flame: A healthy burner flame should be steady and blue. Yellow flames suggest incomplete combustion or ventilation problems.
- Unusual Odors: Burning smells can indicate dust or debris on the burners. A gas smell may point to a leak and requires immediate attention.
- Insufficient Heat: If your furnace struggles to reach the set temperature, the burners might not be functioning correctly.
How to Address Burner Problems
- Schedule Regular Maintenance: Annual tune-ups can prevent debris buildup and ensure burners operate efficiently.
- Clean Burners: Turn off the furnace, remove the burners, and gently clean them with a brush. Consult your owner’s manual or a technician if unsure.
- Inspect the Ignition System: Check for a working ignitor or pilot light. Replace faulty components as needed.
- Call a Professional: For gas supply issues or extensive repairs, it’s best to contact a licensed HVAC technician.
Why Timely Repairs Are Important
Ignoring malfunctioning burners can lead to:
- Higher energy bills due to inefficient heating.
- Increased risk of carbon monoxide leaks.
- Potential damage to other furnace components.
When to Replace Your Furnace
If your furnace is older (15+ years) and burner issues are recurring, replacing the unit may be a more cost-effective solution.
For reliable furnace repair and maintenance, contact a trusted HVAC professional. Taking proactive steps ensures your home stays warm and safe during the colder months.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.
The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.

Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.

This is a professional team that's easy to deal with. I would strongly recommend them

Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!
