- Before attempting to relight your furnace pilot light, it’s crucial to understand why it may have gone out in the first place. Common reasons include:
- Drafts: Strong drafts can disturb the pilot light flame.
- Dirt: Dust and debris can accumulate on the pilot light or sensor, causing an interruption.
- Power outages: A power outage can reset the pilot light.
- Gas supply issues: Low gas pressure or a closed gas valve can hinder the pilot light from staying lit.
How to Relight a Furnace Pilot Light
Materials you’ll need:
- Screwdriver
- Lighter or matches
- Gloves (optional)
Safety First!
- Turn off gas: Locate the gas valve on the gas line leading to your furnace. Turn it clockwise to shut off the gas supply.
- Wait 5 minutes: Allow any residual gas to dissipate before proceeding.
- Open a window: Ensure proper ventilation to prevent gas buildup.
Step-by-Step Instructions:
-
Locate the pilot light: Open the furnace door or access panel. The pilot light is usually located at the bottom of the burner assembly.
-
Light the pilot light: Hold a lighter or match near the pilot light. Simultaneously, press the red reset button on the gas valve.
- If the pilot light doesn’t ignite immediately, hold the reset button for 30-60 seconds before releasing it. Repeat step 2.
-
Keep the pilot light lit: Once the pilot light is lit, keep the reset button pressed for an additional 1 minute. This allows the thermocouple to heat up and generate a spark to maintain the pilot light.
-
Release the reset button: Slowly release the reset button. The pilot light should remain lit on its own.
-
Adjust the flame: If the pilot light flame is too high, turn the gas adjustment screw counterclockwise. For a smaller flame, turn it clockwise. The ideal flame should be about 1/2 inch tall.
-
Close the furnace door: Once the pilot light is stable, close the furnace door or access panel.
-
Open the gas valve: Return to the gas valve and turn it counterclockwise to open the gas supply.
Troubleshooting Tips
- Check for obstructions: Make sure the pilot light is free of dirt or debris. Use a vacuum cleaner to remove any obstructions.
- Inspect the thermocouple: The thermocouple is responsible for detecting the pilot light flame. If it’s damaged, the pilot light will not stay lit.
- Reset the furnace: If the pilot light continues to go out, try resetting the furnace by turning it off at the circuit breaker or fuse box. Wait a few minutes and turn it back on.
- Call a professional: If you’re unable to relight the pilot light or encounter any other issues, don’t hesitate to contact a qualified HVAC technician.
