A pilot light is a small flame that ignites the gas burner in your furnace. It’s important to keep it lit, especially during the cold season, to ensure your home stays warm and comfortable. 

However, sometimes the pilot light may go out due to various reasons, such as a draft, a clogged orifice, or a faulty thermocouple

In this blog post, I will show you how to relight your Goodman furnace pilot light in a few easy steps. But before we begin, let me remind you of some safety precautions you should take when dealing with gas appliances:

  • Make sure you have a working carbon monoxide detector in your home. Carbon monoxide is a colorless, odorless, and deadly gas that can be produced by incomplete combustion of natural gas or propane.
  • Turn off the gas supply valve before attempting to light the pilot light. This will prevent any gas leaks or explosions if something goes wrong.
  • Wear gloves and eye protection to avoid burns or injuries from the flame or hot metal parts.
  • Keep children and pets away from the furnace area while you work on it.
  • If you smell gas or hear a hissing sound, do not try to light the pilot light. Call a professional technician or your gas company immediately.

How Do You Ignite A Goodman Furnace Pilot Light?

Now that you are ready, follow these steps to light your Goodman furnace pilot light:

  1. Locate the gas valve on your furnace. It should be near the bottom of the unit, with a red knob that says “ON”, “OFF”, or “PILOT”.
  2. Turn the knob to the “OFF” position and wait for at least five minutes to let any residual gas clear out of the system.
  3. Turn the knob to the “PILOT” position and press it down. This will allow gas to flow to the pilot light.
  4. Use a long match or a barbecue lighter to ignite the pilot light. You should see a small blue flame near the burner.
  5. Hold the knob down for about 30 seconds to heat up the thermocouple, which is a metal rod that senses the flame and keeps the gas valve open.
  6. Release the knob and check if the pilot light stays on. If it does, turn the knob to the “ON” position and adjust the thermostat to your desired temperature.
  7. If the pilot light goes out, repeat steps 3 to 6 until it stays on. If you still have trouble lighting it, call a professional technician for assistance.

These steps should help you ignite your Goodman furnace pilot light safely.

Where is the Goodman Furnace Pilot Light Located?

If you’re trying to locate your Goodman furnace pilot light, you might be thinking of older furnace models that utilized a standing pilot light that always remained lit. 

However, many modern Goodman furnaces, like other newer furnaces, do not have a traditional standing pilot light. Instead, they use electronic ignition systems, either an intermittent pilot (IP) or a hot surface ignition (HSI), which only ignite when the furnace is activated.

Here’s a general guide:

  • Standing Pilot Light: If you have an older furnace model with a standing pilot light:
    • Open the furnace access panel or door.
    • Look toward the bottom of the unit. Typically, the pilot light is situated between the burners.
    • It should be a small blue flame that stays lit continuously.
  • Electronic Ignition: If you have a newer Goodman furnace model:
    • Intermittent Pilot (IP): This type of system has a pilot that is electronically ignited only when the furnace is running. It won’t have a flame when the furnace is off.
    • Hot Surface Ignition (HSI): This is a resistor element that heats up to ignite the burners directly. It does not have a pilot flame at all.

What Causes Furnace Not to Ignite?

There are several possible causes for a furnace not to ignite, depending on the type of furnace and the fuel source. Some of the common causes are:

  • Gas or oil furnace not igniting because of dirty burners. Dirt or grime on the burners themselves can restrict the flow of air and prevent the burners from lighting. If the burners look dirty, you can try cleaning them to get them to ignite.
  • Gas or oil furnace not igniting because of faulty gas valve or gas supply. If the gas valve or gas supply is obstructed, damaged, or closed, the furnace will not be able to get enough fuel to start up. You can check the gas valve and gas line for any signs of blockage or damage, and make sure they are open and functioning properly. If you smell gas near your furnace, you should leave your house immediately and call your gas company.
  • Gas or oil furnace not igniting because of bad ignitor or flame sensor. The ignitor is the device that creates a spark to light the gas or oil, and the flame sensor is the device that detects the presence of a flame and signals the gas valve to stay open. If either of these components is faulty, the furnace will not ignite or stay lit. You can test the ignitor and flame sensor with a multimeter to see if they are working correctly, and replace them if needed.
  • Electric furnace not igniting because of dead thermostat batteries or bad thermostat wiring. The thermostat is the device that controls when the furnace turns on and off, and sends a signal to the electric ignitor to start heating up. If the thermostat batteries are dead, or the wiring is loose or damaged, the furnace will not receive the signal to ignite. You can check the thermostat batteries and wiring, and replace them if necessary.
  • Electric furnace not igniting because of faulty electric ignitor. The electric ignitor is the device that heats up to a high temperature and ignites the air-fuel mixture in the combustion chamber. If the electric ignitor is broken, worn out, or dirty, it will not heat up enough to ignite the fuel. You can inspect the electric ignitor for any signs of damage or dirt, and replace it if needed.
  • Furnace not igniting because of clogged air filter. The air filter is the device that filters out dust and debris from the air that enters the furnace. If the air filter is clogged, it will reduce the airflow and prevent enough oxygen from reaching the combustion chamber. This will cause incomplete combustion and prevent the furnace from igniting. You can check the air filter and clean or replace it if it is dirty.

These are some of the common causes for a furnace not to ignite, but there may be other factors involved as well. If you are not sure how to troubleshoot or fix any problem especially with your Goodman furnace pilot light, it is best to call a professional HVAC technician for assistance. They have the tools and expertise to diagnose and repair your furnace safely and efficiently.

What Is the Best Color For the Pilot Light Flame? 

The best color for the Goodman furnace pilot light flame is blue. This indicates that the gas is burning efficiently and cleanly. If the flame is yellow or green, it means that there is some impurity or contamination in the gas or the air.

This could cause carbon monoxide production, which is dangerous for your health and safety. If you notice a yellow or green flame, you should call a professional technician or your gas company to inspect and fix the problem.


Lighting your Goodman Furnace Pilot Light safely is paramount for both your home’s comfort and safety. By meticulously adhering to the outlined steps, you ensure that your Goodman Furnace Pilot Light is ignited without risks. Always consult the owner’s manual, and if in doubt, seek expert guidance. Proper care ensures your furnace’s longevity and efficient performance. Stay warm with peace of mind!
