Furnace Pilot Light Malfunctioning

If your furnace pilot light is malfunctioning, it can prevent your heating system from working effectively. Here’s a detailed guide to identify and resolve common pilot light issues:


1. Understand the Problem

The pilot light is a small flame that ignites the burners in your furnace. If it’s malfunctioning or won’t stay lit, your furnace may not generate heat.



2. Common Causes

  1. Dirty Pilot Orifice
    Dust, debris, or soot can clog the pilot orifice, reducing or extinguishing the flame.


  2. Thermocouple Issues
    The thermocouple is a safety device that shuts off the gas supply if the pilot light goes out. If it’s faulty or misaligned, the pilot may not stay lit.


  3. Drafts or Airflow Problems
    Strong drafts near the furnace can blow out the pilot light.


  4. Gas Supply Issues
    Insufficient gas pressure or a gas valve issue can prevent the pilot from staying lit.


  5. Malfunctioning Gas Control Valve
    If the gas valve is faulty, it may not release enough gas for the pilot light to ignite.



3. Troubleshooting Steps

a. Inspect the Pilot Light

  • Check if the flame is burning. A healthy pilot light should be steady and blue. If it’s yellow or flickering, it may indicate a problem with the gas mixture or airflow.

b. Relight the Pilot Light

  1. Turn off the furnace and wait for gas to dissipate (5-10 minutes).
  2. Locate the pilot light assembly and turn the gas control knob to "Pilot."
  3. Hold down the reset button and use a long lighter to ignite the flame.
  4. Release the button slowly after 30-60 seconds.

c. Clean the Pilot Orifice

  • Turn off the gas supply and use a needle or compressed air to remove debris from the pilot orifice.

d. Test the Thermocouple

  • Ensure the thermocouple is in direct contact with the flame. If misaligned, adjust its position.
  • If it’s worn out, replace the thermocouple.

e. Check for Drafts

  • Seal any openings near the furnace to prevent drafts from blowing out the flame.

f. Inspect Gas Supply

  • Verify that the gas valve is open and gas is flowing properly. Consult a professional if there’s a suspected gas pressure issue.

4. When to Call a Professional

  • If the pilot light still won’t stay lit after troubleshooting.
  • You suspect a gas leak or faulty gas valve.
  • There’s a persistent yellow or weak flame.

5. Maintenance Tips

  1. Schedule annual furnace maintenance.
  2. Keep the pilot light assembly clean.
  3. Regularly check for drafts and airflow issues.
  4. Monitor your furnace’s performance during the heating season.

Addressing a malfunctioning pilot light promptly ensures a warm and safe home. If in doubt, always consult a licensed HVAC technician.

Thanks to the guys at Twintech Heating for a great job installing a new hot water tank. They set a time and day to remove the old tank and install the new one. They were on time and had the work done quickly and cleaned up after they were finished. Excellent work and great value.

by Marilyn in Milton on Twintech Heating and Cooling

In November, we contacted Twintech for a quote on a high efficiency furnace plus installation. Dave, the sales representative for the company was very friendly and informative. Upon arrival at our home, he willingly showed us his company licenses, clearly explained the operation of a high efficiency furnace and answered all our questions to our satisfaction. As well, Dave was the only sales representative that we contacted that was willing to make the arrangements for an energy audit. For us, this was a big plus as we found the government rebate program somewhat confusing to navigate. The furnace was installed on the date that was arranged in an efficient and professional manner by Greg (the owner) and Peter. Both men worked diligently, throughout a long day to complete the job and upon finishing, left the job site immaculate. When a neighbour raised concerns about the furnace venting location, Greg located an alternative location and resolved the situation with diplomacy. We chose the Napoleon furnace for its excellent warrant;y on the heat exchanger and because it was made in Canada! In addition, to the furnace warranty, Twintech offered us a 5 year warranty on labour which speaks to the quality and pride this team has in their workmanship. It has been over a month now (with some of the coldest January days on record) since we have had the furnace installed. The furnace runs quietly and distributes heat more evenly throughout our 90 year old Toronto home. We can't speak highly enough of the Twintech team and are very satisfied with their workmanship and job ethics. We have no hesitation about recommending them.

by Barry in Toronto on Twintech Heating and Cooling

What more could you ask for! Grant and Greg Dainty provided a professional,diligent and thorough approach to the installation of my furnace. I would highly recommend there services.

by Hector in Scarborough on Twintech Heating and Cooling

Last week our Furnace failed overnight. We called Twintech to help us get it running again. They did a really thorough check on it, and got it running in less than an hour. Given that it was an old Furnace (+20 years old), we were giving two options: repair it or replace it. Instead of doing a repair on it that could break in a week or two, they recommended us to change it. I like that they were honest on the recommendation, not forcing a new furnace on us. At the end we went with a new Furnace. Twintech solutions service & salesman gave us recommendation on the size of the unit and many options that could work for our home. They ended up doing an excellent work in our furnace, replacing the filter to a better option and replacing some pieces that had water damage. They cleaned after themselves and leave everything even better than what they found. They even went far and beyond tiding up the hose connections that we had on the basement.

by Ryan Doherty in Whitby on Twintech Heating and Cooling

I am in the process of finishing my basement and wanted to make sure I got the low hanging duct work fixed in advance. After reviewing 5 quotes I selected Twintech to award the contract to. The price was competitive however what won me over was Grant's (co-owner) attention to detail and his ability to focus on what my goals and priorities were for the project. His team completed the job over 3 days as there was significant duct work changes and the relocation of all of the equipment. They also completed the job with little downtime so we weren't left overnight without heat during freezing winter temperatures.

by Private User from Oshawa on Twintech Heating and Cooling

My father woke up to no heat one Saturday morning. We had a few names that friends had recommended but while checking out the companies' ratings on HomeStars, we found Twintech with great ratings too. The other companies either didn't get back to us or didn't have time to come at such short notice. TwinTech made the time in their schedule for what they judged to be an emergency: no heat in the home of an elderly person. At no extra fee for a short notice, weekend visit. They recommended an upgraded furnace unit and explained that we would qualify for a rebate that would bring the price down to that of a lower model. They set us up with the rep from the MNR that covers the rebate so that we didn't have to deal with the paperwork & phone calls ourselves. Installation was quick, efficient, & smooth. We were so pleased with their service we ordered a new water heater too. Both are working great (efficient & quiet!) & my father is safe & comfortable. We can't say enough about how pleased we are with their service. We have already recommended them to others.

Twintech Heating & Cooling. I just want to say thanks for helping me . My Furnace stopped working. And l phone Dave Getgley he set me up with Greg. What an amazing team they did a great job in setting me up with a new Furnace. Anyone that needed a new Furnace these are the guys to call. Thanks again for a job well done.

by Peter from Ajax on Twintech Heating and Cooling

Our home has had poor heating and air conditioning the past couple of years. Dave recommended a Goodman solution with more power than we had. Grant and Greg installed the units in late November. Heating is better than ever. We have a warm home again and look forward to the winter. Can't wait to see how the AC runs in 2018. Job was super clean and professionally done. Highly recommended.

by iqster in Toronto on Twintech Heating and Cooling

Received a new range and needed someone to disconnect the old range and connect the new gas range. They did a thorough job and were kind enough to remove the old range from the house. Thank you!

by AJM in Pickering on Twintech Heating and Cooling

Very satisfied with this company! Salesperson Dave was very good, very knowledgeable and gave me the impression that he wanted to sell me what I needed rather than what would put the most money in the company's pocket. He also called back after the installation to see if I was satisfied with the result. The installation crew of Greg, Grant and Peter did a great job. They arrived on time, completed the job quickly, answered all my questions and thoroughly cleaned up. They told me to call if I had any further questions. They left me with the impression that they really cared about their work and my satisfaction and that it wasn't " just a job". Prior to researching for a new furnace, I had never heard of this company but I'm glad that I did and would highly recommend them to anyone looking for a new furnace or air conditioning unit. They may be small but they do a great job!!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all!

I definitely recommend TwinTech!
