Troubleshooting Your Furnace Pilot Light

One of the most difficult aspects of furnace repair is diagnosing and repairing a "pilot light won't light" issue. If your furnace's pilot light won't ignite or stay lit, your heating system might not function correctly. Fortunately, with the right guidance and expert information, this problem can be identified and optimized quickly and efficiently.

In this article, we look at the underlying causes of why your furnace's pilot light won't light and how to troubleshoot and resolve the issue.

What Is a Pilot Light and What Does It Do?

The pilot light is a small flame located within the main combustion chamber of your furnace. When the furnace blower starts up, it pulls air from around the pilot light and uses it to ignite the main furnace burners. If the pilot light flame is weak or does not ignite at all, the main burners won't function properly and your home won't be heated to the desired temperature.

Why Won’t My Pilot Light Stay Lit?

A furnace pilot light won't light for a variety of reasons. Most of the time, it is a result of a dirty or clogged flue, insufficient corrosion-resistant materials around the burners, or an undersized flue. Other common reasons include air or gas leaks, cracked valve seats, or a restricted gas flow.

The first step in troubleshooting a pilot light won't light issue is to visually inspect the entire system. Check all vents, ducts, and flue pipes for any signs of damage. Make sure that the flue pipes aren't clogged or blocked. Clean the pilot and inspect the gas settings, the gas filter, and the gas valves for any ignition issues.

How to Re-Ignite the Pilot Light

If the pilot light has gone out, the next step is to re-ignite it. Follow these steps:

  1. Turn the furnace off
  2. Wait 5 minutes for the gas to dissipate
  3. Turn the furnace on and locate the reset button, usually found on the pilot light assembly
  4. Press and hold the reset button for 30 seconds until the pilot light ignites
  5. If the pilot light does not ignite, check for air leaks or blocked flue pipes
  6. Make sure the gas is turned on
  7. Make sure the gas valve is in the open position

What to Do if the Pilot Light Won’t Ignite

If you're unable to ignite the pilot light following the instructions above, it's time to seek professional help. The problem could be related to the thermostat, the pilot light tube, the flame sensor, or a faulty control board. An experienced furnace repair technician can diagnose and repair the issue quickly and efficiently.
