How to Light a Goodman Furnace: A Step-by-Step Guide: 1 Minute to Safely Igniting Your Goodman Furnace

Knowing how to light a Goodman furnace can save you time and provide warmth when temperatures drop. This process is straightforward and can be accomplished with just a few steps. Let’s dive into how you can efficiently ignite your Goodman furnace.

Step 1: Safety First

Before you start, ensure your safety by turning off the gas valve and allowing the furnace to cool down. Check for any gas leaks and make sure the area is well-ventilated. If you notice a strong smell of gas, do not proceed.

Step 2: Locate the Ignitor

The ignitor on a Goodman furnace is usually found near the burner. For many models, it’s electronic, so make sure you have a lighter or match ready if your model requires it. Open the furnace door to access the controls.

Step 3: Set the Thermostat

Next, adjust your thermostat to the desired temperature to prompt the furnace to turn on. This is crucial as it signals the furnace to ignite. Ensure the thermostat is set to a heating mode.

Step 4: Light the Furnace

If your model uses a standing pilot light, turn the gas control knob to 'Pilot.' Hold down the reset button and light the pilot using a lighter or match. Continue holding the reset button for about 30 seconds to ensure the pilot stays lit. If it does not stay lit, repeat this step. For electronic ignitors, simply follow the prompts on the thermostat.

Step 5: Confirm Operation

Once the pilot is lit or the electronic ignitor activates, you should hear the furnace start up. Close the furnace door and check the burner. If it's operating properly, you should see flames and feel heat coming from the vents after a few minutes.

Common Issues

If your Goodman furnace does not ignite, check the following: gas supply, pilot light condition, and thermostat settings. Sometimes, the furnace may require maintenance if it fails to work correctly after troubleshooting.

FAQ

Q: What should I do if the pilot light keeps going out?A: If the pilot light won’t stay lit, check for drafts, a faulty thermocouple, or you may need to call a professional to address the issue.

Q: How often should I service my Goodman furnace?A: It’s recommended to service your furnace annually to ensure it's functioning properly and safely. Regular maintenance can prevent breakdowns and extend the lifespan of your system.
