Step 1: Identify the Pilot Light

Locate the pilot light on your furnace. It’s usually a small flame that’s located at the bottom or side of the furnace. Look for a small metal or plastic tube that’s connected to the main burner. This tube is responsible for igniting the main burner when you turn on the furnace.

Step 2: Turn Off the Power

Make sure to turn off the power to the furnace before attempting to light the pilot light. This is an important safety precaution to prevent any accidental ignition or electrical shock. Locate the circuit breaker or fuse box and flip the switch or remove the fuse.

Step 3: Remove the Pilot Light Cap

Remove the pilot light cap by unscrewing or sliding it off. Be careful not to touch any of the internal components, as they may be hot or electrical.

Step 4: Light the Pilot Light

Hold a flame from a lighter or matches to the pilot light. Keep the flame steady and aim it at the pilot light opening. Make sure the flame is blue and not yellow, as a yellow flame can indicate a faulty pilot light.

Step 5: Adjust the Pilot Light

Adjust the pilot light by turning the knob or adjusting the screw. Make sure the pilot light is burning steadily and not flickering.

Step 6: Replace the Pilot Light Cap

Replace the pilot light cap by screwing it back on or sliding it back into place.

Step 7: Turn On the Power

Turn on the power to the furnace by flipping the switch or replacing the fuse.

Step 8: Check the Furnace

Check the furnace to make sure it’s working properly. Listen for any unusual noises or sounds, and check for any signs of carbon monoxide.

Common Issues and Troubleshooting

  • Pilot light won’t stay lit: Check the pilot light cap for any blockages or debris. Make sure the pilot light is adjusted correctly.
  • Pilot light is too bright: Adjust the pilot light by turning the knob or screw.
  • Furnace won’t turn on: Check the circuit breaker or fuse box to make sure the power is turned on. Check for any blockages or debris in the pilot light cap.

Safety Precautions

  • Never attempt to light the pilot light without turning off the power.
  • Never touch any of the internal components, as they may be hot or electrical.
  • Make sure the area is well-ventilated to prevent carbon monoxide buildup.
