How to Relight the Pilot Light on Your Old Furnace: 1 Minute to Restore Warmth in Your Home

Relighting the pilot light on an old furnace is a common homeowner maintenance task, especially when dealing with older gas heating systems. Before you start, always prioritize safety: confirm there's no gas smell, turn off the furnace, and give the area time to ventilate. Here's a step-by-step guide to get your old furnace running again:

1. Locate the Pilot Light Assembly: This is typically near the bottom of the furnace and has a small valve with “on,” “off,” and “pilot” settings.
2. Turn Off the Gas: Rotate the valve to the “off” position and wait at least five minutes to clear any residual gas.
3. Switch to “Pilot” Setting: Turn the valve to the “pilot” position. This step is crucial for gas safety.
4. Hold Down the Reset Button: Locate and hold down the reset (or ignition) button while using a long lighter or match to ignite the pilot. Continue to hold the button for 30-60 seconds to allow the thermocouple to heat up.
5. Release and Monitor: Release the reset button. The pilot should stay lit. If it goes out, repeat the process, making sure to hold the button longer this time. If the flame still won’t stay lit, the thermocouple may be faulty and require professional attention.
6. Turn Valve to “On”: Once the pilot stays lit, turn the valve to “on,” then restore furnace power.

From a designer’s perspective, keeping your heating systems in top condition means your home remains comfortable and functional all year. If you’re planning a full basement remodel or thinking about updating your utility room, consider integrating contemporary mechanical solutions into your home designer layout to make maintenance like this safer and more accessible.

Tips 1:

Always store a flashlight near your furnace so you have proper visibility when working in low-light conditions. Inspect the area for any dust or debris; a clean workspace helps prevent accidental fires and makes spotting issues easier.
