How To Safely Relight Your Furnace

Older gas furnaces use pilot lights to ignite the burners when heating is required. The pilot light is a small standby flame that burns all of the time. When it goes out, your furnace cannot function. Because gas is involved, you need to know how to safely relight your furnace. If your pilot light goes out more than once, you should find out why it’s failing. Your aging furnace likely needs repairs or replacement.

Why Would A Furnace Pilot Light Go Out?

Most reasons behind a pilot light going out can be resolved with maintenance or a new part. Furnace repair technicians from Oliver can diagnose the problem and recommend how to proceed. When you follow the steps for how to safely relight your furnace, look for evidence behind the problem.

Tools Needed

  • Screwdriver
  • Flashlight
  • Lighter

Step by Step Directions:

  1. Remove the panel covering the front of the furnace. You may need a screwdriver to do this.
  2. You should see the pilot light near the bottom of the unit. Inspect the area with a flashlight.
  3. Sniff the area for the odor of natural gas. If you smell a strong, persistent gas odor, stop and call your utility to report an emergency gas leak. Open your windows too.
  4. If you do not have a gas leak, proceed with how to safely relight your furnace.
  5. Find the reset switch. It is usually a knob with three settings: pilot, on, and off.
  6. Turn the knob to “off”.
  7. Wait for two or three minutes before doing anything.
  8. After waiting, get ready with your lighter and turn the knob to the pilot.
  9. Now press the knob.
  10. Bring the flaming lighter close to the pilot.
  11. Keep pressure on the knob until you see a new flame on the pilot.
  12. Release the knob.
  13. Watch the flame for a while to confirm that the pilot is staying lit.
  14. Monitor the furnace to make sure that the pilot remains lit.
