Why Is Your Furnace Pilot Light Important?

The pilot light is a small, continuously burning flame that ignites the gas burner when your furnace is operating. If the pilot light won’t stay on, your furnace won’t produce heat, leading to cold indoor temperatures and potential safety hazards. Furnaces with a standing pilot light are common in older gas furnace models, while newer high-efficiency furnaces use electronic ignition systems. If your furnace has a standing pilot light that keeps going out, it’s time to call a professional to inspect and repair the issue.

Common Reasons Why Your Furnace Pilot Light Won’t Stay On

If your pilot light won’t stay lit, there could be several underlying causes. Here are the most common reasons why your furnace pilot light keeps going out:

1. Dirty or Faulty Thermocouple

✔ What is a thermocouple? A thermocouple is a safety device that detects if the pilot light is lit. If the pilot light goes out, the thermocouple shuts off the gas supply to prevent leaks. ✔ Signs of a faulty thermocouple:

• Pilot light keeps going out after a few seconds
• Furnace won’t ignite at all
• You smell gas near the furnace

✔ Solution:

• Cleaning the thermocouple may fix the issue.
• If it’s worn out or damaged, it needs to be replaced.

✔ Cost of Thermocouple Replacement: $150 – $400

2. Clogged Pilot Orifice or Burner Assembly

✔ What is the pilot orifice? The pilot orifice is a small opening where gas flows to keep the pilot light burning. If it becomes clogged with dirt, dust, or debris, the flame won’t stay lit. ✔ Signs of a clogged pilot orifice:

• Weak or flickering pilot light
• Yellow or orange flame instead of blue
• Furnace constantly shutting down

✔ Solution:

• The pilot orifice and burner assembly need to be cleaned to remove debris.
• A professional HVAC technician can safely disassemble and clean these components.

✔ Cost of Pilot Orifice Cleaning: $100 – $300

3. Faulty Gas Valve or Gas Supply Issues

✔ What does the gas valve do? The gas valve controls the flow of natural gas to the pilot light and burner. If it’s damaged or blocked, your furnace won’t stay lit. ✔ Signs of a gas valve issue:

• Pilot light goes out immediately after releasing the reset button
• No gas flow to the burner
• You hear a clicking noise but no ignition

✔ Solution:

• A professional HVAC technician can inspect and replace a faulty gas valve.
• If there’s a gas supply issue, FortisBC or your local gas provider may need to investigate.

✔ Cost of Gas Valve Replacement: $300 – $700

4. Drafts or Poor Ventilation

✔ How does a draft affect the pilot light? Strong airflow from vents, windows, or a faulty flue pipe can blow out the pilot light. ✔ Signs of ventilation issues:

• Pilot light goes out on windy days
• You hear whistling or airflow noises near the furnace
• Weak or flickering flame

✔ Solution:

• Sealing drafts around windows, doors, and vents can prevent the issue.
• A technician can inspect and repair the flue pipe or venting system.

✔ Cost of Flue Pipe Repair: $200 – $600

5. Malfunctioning Control Board or Flame Sensor

✔ What does the control board do? The furnace control board regulates ignition and fuel supply. If it’s damaged or faulty, the pilot light won’t stay on. ✔ Signs of a malfunctioning control board:

• Pilot light turns on but the burner doesn’t ignite
• Furnace cycles on and off frequently
• Error codes on your thermostat or furnace display

✔ Solution:

• Repair or replace the control board or flame sensor.

✔ Cost of Control Board Replacement: $400 – $1,200

How to Troubleshoot a Furnace Pilot Light That Won’t Stay On

Before calling a technician, you can try the following troubleshooting steps: ✔ Step 1: Turn off the furnace and wait 5 minutes before relighting. ✔ Step 2: Locate the pilot light assembly and remove dust with compressed air. ✔ Step 3: Hold down the reset button and try relighting the pilot. ✔ Step 4: If the flame goes out immediately, check the thermocouple. ✔ Step 5: If troubleshooting doesn’t work, call a professional for repair. ⚠ Important: If you smell gas, leave your home immediately and call FortisBC or 911. Do NOT attempt to relight the pilot if you suspect a gas leak.
