How to Light a Pilot Light on a Goodman Furnace: Step-by-Step Guide to Relaunch Your Heating System Effortlessly

Relighting the pilot light on your Goodman furnace is a straightforward process, but it’s crucial to follow safety procedures. First, ensure your thermostat is set to the “off” position, and then locate the furnace’s gas control knob and pilot assembly. Typically, you’ll find the control knob with "Off," "On," and "Pilot" settings near the bottom of the unit.

Turn the knob to the "Off" position and wait at least five minutes to allow any lingering gas to dissipate. This step is essential for safety. Next, turn the knob to the "Pilot" setting. Hold down the knob to begin the gas flow to the pilot. While holding it down, use a long-reach lighter or match to ignite the pilot light. Continue holding the knob for about 30 seconds after the flame ignites to ensure the thermocouple heats up and the flame stays lit. Once the pilot light is stable, release the knob and set it to the "On" position. Finally, reset your thermostat to the desired temperature and confirm that the furnace ignites as expected.

As an interior designer, I know lighting is everything—not just for comfort but also for safety. A well-lit mechanical room not only makes tasks like relighting a pilot easier but also creates a safer environment for future maintenance. For design professionals or DIY enthusiasts considering an upgrade to their home’s utility spaces, integrating thoughtful lighting and layout solutions can streamline both maintenance and daily living.

Tips 1:

If the pilot light won’t stay lit or if you smell gas, do not attempt to relight it repeatedly. Evacuate the area and contact a certified HVAC technician immediately, as this can indicate a faulty thermocouple or gas leak, both of which require professional attention.
