Keeping your home warm during Canada’s long, frigid winters depends heavily on your furnace working properly. But if the pilot light suddenly goes out, your furnace won’t deliver the heat you rely on. Many homeowners panic when this happens—but the good news is that it’s often fixable with the right steps.
In this guide, we’ll cover everything you need to know about Steps to Take When Your Pilot Light Goes Out: Detailed Instructions. You’ll learn why the pilot light is so important, common causes of it going out, safety precautions, how to relight it properly, troubleshooting tips, and when to call professionals like GM HEATING AND COOLING INC for expert help.
What Is a Pilot Light, and Why Does It Matter?
The pilot light is a small flame inside your gas furnace that acts as the ignition source for the burners. Whenever your thermostat signals the need for heat, this flame lights the burners, allowing the furnace to produce warm air.
When the furnace pilot light is out, the system simply cannot run. Without it, you’re left with cold air blowing through your vents—or worse, no airflow at all. That’s why understanding the steps to take when your pilot light goes out: detailed instructions is so essential for Canadian homeowners.
Common Reasons the Furnace Pilot Light Goes Out
If you notice that your furnace isn’t heating, the first thing to check is whether the pilot light is burning. Several factors may cause it to go out:
- Drafts or Ventilation Issues – Sudden drafts near the furnace can blow out the flame. This is especially common in basements or utility rooms with poor insulation.
- Dirty Pilot Assembly – Dust and debris buildup can block the flame, making it unstable. Regular cleaning prevents this.
- Faulty Thermocouple – This safety device shuts off the gas if it senses the pilot flame isn’t present. If it’s dirty, bent, or broken, it may shut off the gas incorrectly.
- Gas Supply Problems – Low gas pressure or a malfunctioning valve can cause weak or inconsistent flames.
- Aging Furnace Components – Over time, the pilot orifice or burner parts may wear out, leading to repeated outages.
Understanding the root cause is the first step in furnace troubleshooting.
Safety First: Precautions Before Relighting
Before you attempt the steps to take when your pilot light goes out: detailed instructions, safety should be your top priority. Furnaces involve both natural gas and open flames, so precautions are non-negotiable:
- Check for Gas Smell: If you smell gas, leave the home immediately and contact your gas provider. Do not attempt to relight the furnace.
- Ventilate the Area: Open windows or doors around the furnace to allow fresh air circulation.
- Remove Flammable Items: Clear away paper, cardboard, or any other combustible items near the unit.
- Wear Protective Gear: Safety goggles and gloves can help protect you during the process.
- Have a Fire Extinguisher Nearby: Always keep one within reach in case of emergencies.
By following these precautions, you’ll reduce risks while working with your furnace.
Steps to Take When Your Pilot Light Goes Out: Detailed Instructions
Now, let’s walk through the safe and proper process of relighting your furnace’s pilot light.
- Turn Off the Gas Control: Find the control knob on your furnace’s gas valve and turn it to the Off position. This ensures no gas is flowing while you work.
- Wait for Gas to Clear: Allow at least five minutes for any residual gas to dissipate. This step is critical for avoiding accidental ignition.
- Locate the Pilot Assembly: Typically found near the furnace’s bottom, behind a small access panel.
- Turn Knob to “Pilot”: Switch the gas control knob to Pilot mode.
- Press and Hold the Knob: Depress the knob to allow gas to flow to the pilot.
- Ignite with a Long Lighter: While holding the knob down, place a flame at the pilot orifice. A small blue flame should appear.
- Hold for 60 Seconds: Keep the knob pressed for about a minute, allowing the thermocouple to heat and confirm the flame is stable.
- Release Slowly: If the flame holds steady, release the knob and turn it to On.
- Replace the Access Panel: Secure the cover back in place.
- Test the Furnace: Adjust your thermostat to call for heat and ensure the burners ignite properly.
If everything goes smoothly, your furnace should start heating again.
What If the Pilot Light Won’t Stay Lit?
Sometimes, even after carefully following the steps to take when your pilot light goes out: detailed instructions, the flame won’t stay lit. This often indicates a deeper issue, such as:
- Weak Pilot Flame – May require adjusting the flame size.
- Dirty Thermocouple – Needs cleaning or repositioning to stay in contact with the flame.
- Faulty Thermocouple – May need replacement if cleaning doesn’t help.
- Gas Supply Issues – Could be a regulator or valve problem, requiring professional service.
If repeated attempts fail, don’t force it—this is the time to call experts like GM HEATING AND COOLING INC for a safe, lasting repair.
When to Call a Professional
While many homeowners can relight a furnace pilot light themselves, there are times when calling a technician is the smartest option. Seek professional help if:
- The pilot light goes out repeatedly after relighting.
- You suspect issues with the thermocouple or gas valve.
- There are unusual sounds or odors coming from the furnace.
- Your furnace is more than 15 years old and experiencing frequent problems.

FAQs
1. Why does my furnace pilot light keep going out?
Your pilot light may keep going out due to drafts, a dirty pilot assembly, a faulty thermocouple, or low gas pressure. If the problem persists, it’s best to call GM HEATING AND COOLING INC for professional furnace troubleshooting.
2. Is it safe to relight the pilot light myself?
Yes, it’s generally safe if you follow proper safety precautions, like turning off the gas and waiting a few minutes before relighting. However, if you smell gas or feel unsure, leave the task to an HVAC professional.
3. How long should I hold the pilot button when relighting?
You should hold the button for about 60 seconds after the flame ignites. This gives the thermocouple enough time to heat up and confirm the flame is steady.
4. What should I do if the pilot light won’t stay lit after multiple attempts?
If the flame keeps going out despite following the steps to take when your pilot light goes out: detailed instructions, there may be a deeper issue with the thermocouple, gas valve, or regulator. Contact a licensed technician for diagnosis.
5. Can a dirty furnace cause the pilot light to go out?
Yes. Dust, dirt, and debris buildup around the pilot assembly or burner can cause the flame to weaken or go out. Regular furnace maintenance helps prevent this.
6. When should I replace my furnace instead of repairing the pilot light?
If your furnace is more than 15 years old and requires frequent repairs, upgrading to a newer, more efficient system may be more cost-effective in the long run.
