If your furnace suddenly stops working, there could be a number of causes. If you discover that the pilot light has gone out, you’ll need to relight your pilot light to get your furnace running again. It’s a fairly straightforward process but it must be done safely to avoid damaging your furnace, causing a gas leak, or getting hurt. Follow these 9 steps to relight your furnace safely.
Steps to Relight Your Furnace
1. Turn your furnace off and find the pilot light. The pilot light is the small flame near the bottom of your furnace. It might be behind a small panel or access door that you can open by pressing a button or turning a latch.
2. Turn off the gas supply. You can do this by turning the knob or valve located near your furnace. It might be a red or black button. It is usually marked with 3 settings: On, Pilot, and Off. If you can’t find it, consult your furnace manual. Turn the switch to “Off”.
3. Wait a minute or two. Wait a few minutes after turning off the flow of gas before attempting to relight the pilot light. This will allow time for the gas to dissipate from the chamber so you don’t ignite the excess gas.
4. Turn the knob to “Pilot”. For newer furnaces, an automatic pilot light can be relit using the red button alone. For an older furnace, on the other hand, you will need an external flame source, like a long-stemmed lighter or match.
5. Light the pilot light. For a manual pilot light, carefully light the pilot while holding down the red button. Hold the button for 60 seconds.
6. Let go of the button after 60 seconds. The pilot light should stay lit. If it doesn’t, call a professional to assess and diagnose the situation.
7. Turn the gas supply back on. Turn the gas valve to the “On” position. If you don’t do this, your pilot light will go out again.
8. Turn your furnace back on. Also, close the access panel to your pilot light if you have one.
9. Keep an eye on the furnace. Once you relight your furnace, observe the pilot light for a few minutes to ensure it stays lit. Check the surrounding areas for drafts or air sources that could’ve caused the pilot light to go out.
