**Step 1: Turn Off the Gas Supply**
Before attempting to reignite the pilot light, make sure to turn off the gas supply to the furnace. This is a crucial safety precaution to prevent any accidents or gas leaks. Use a gas line shut-off tool to shut off the gas supply at the main gas valve.
**Step 2: Locate the Pilot Light Assembly**
The pilot light assembly is usually located at the bottom of the furnace. You may need to remove a cover or filter to access the pilot light. Use a screwdriver to remove any screws or clips holding the cover in place.
**Step 3: Clean the Burner**
Use a soft cloth or brush to clean the burner and surrounding area of any dirt, debris, or corrosion. This will help ensure a clean and safe burning environment for the pilot light.
**Step 4: Adjust the Pilot Light Adjustment Screw**
The pilot light adjustment screw is usually located near the pilot light or on the pilot light assembly. Use a screwdriver to adjust the screw in a counterclockwise direction until it stops. Then, back it out slightly and test the pilot light to ensure it’s working properly.
**Step 5: Light the Pilot Light**
Hold a flame from a match, lighter, or flashlight to the pilot light assembly until it ignites. You may need to hold the flame for several seconds to ensure the pilot light stays lit.
**Step 6: Adjust the Flame**
Use the pilot light flame shield to adjust the pilot light flame to the correct height. The flame should be about 1-2 inches high.
**Step 7: Turn On the Gas Supply**
Once the pilot light is lit and adjusted, turn on the gas supply to the furnace. Use the gas line shut-off tool to turn on the gas supply at the main gas valve.
Common Issues to Watch Out for
- Failed Pilot Light: If the pilot light doesn’t light, check for any obstructions in the burner or pilot light assembly.
- Pilot Light Flaming Out: If the pilot light flares out or goes out, adjust the pilot light adjustment screw in a clockwise direction and test the pilot light again.
