What to Do When the Pilot Light Goes Out?
A pilot light is a small flame that ignites the main burner of a gas appliance, such as a water heater, furnace, or stove. When the pilot light goes out, it can cause a variety of issues, including reduced performance, incomplete combustion, and even safety hazards. In this article, we’ll explore the causes of a pilot light going out and provide a step-by-step guide on what to do when it happens.
Causes of a Pilot Light Going Out
Before we dive into the solution, it’s essential to understand the common causes of a pilot light going out. Some of the most common reasons include:
• Dirty or clogged pilot orifice: Dirt, debris, or mineral buildup can block the pilot orifice, preventing the pilot light from igniting.
• Faulty thermocouple: The thermocouple is responsible for sensing the pilot light’s temperature and sending a signal to the gas valve to open. A faulty thermocouple can prevent the pilot light from staying lit.
• Low gas pressure: Low gas pressure can make it difficult for the pilot light to stay lit.
• Carbon buildup: Carbon buildup on the pilot orifice or surrounding areas can prevent the pilot light from igniting.
• Malfunctioning pilot assembly: The pilot assembly may be damaged or malfunctioning, preventing the pilot light from staying lit.
Step-by-Step Guide to Relighting the Pilot Light
Relighting a pilot light is a relatively simple process, but it’s crucial to follow the correct steps to ensure your safety and the proper function of your appliance. Here’s a step-by-step guide:
Step 1: Turn Off the Gas Supply
Before attempting to relight the pilot light, turn off the gas supply to the appliance. You can usually find the gas shut-off valve near the appliance or on the gas line. Turn the valve clockwise to shut off the gas supply.
Step 2: Check the Pilot Light Assembly
Inspect the pilot light assembly for any signs of damage or blockages. Make sure the pilot orifice is clear of debris and mineral buildup.
Step 3: Clean the Pilot Orifice
Use a soft brush or a cloth to clean the pilot orifice. Remove any debris or mineral buildup that may be blocking the orifice.
Step 4: Check the Thermocouple
Check the thermocouple for any signs of damage or corrosion. Make sure it’s securely attached to the pilot light assembly.
Step 5: Relight the Pilot Light
Press the pilot light button and hold it for 30 seconds to 1 minute. You should hear a gentle clicking sound as the gas valve opens. Release the button and wait for 30 seconds to 1 minute. The pilot light should reignite.
Step 6: Adjust the Pilot Light
If the pilot light doesn’t stay lit, adjust the pilot light by turning the adjustment screw clockwise or counterclockwise. Make sure the pilot light is at the correct height and distance from the burner.
Table: Pilot Light Adjustment Guidelines
| Appliance | Pilot Light Adjustment |
|---|---|
| Water Heater | Turn clockwise to increase height, counterclockwise to decrease height |
| Furnace | Turn clockwise to increase distance, counterclockwise to decrease distance |
| Stove | Turn clockwise to increase height, counterclockwise to decrease height |
Step 7: Test the Pilot Light
Once you’ve adjusted the pilot light, test it by pressing the pilot light button and holding it for 30 seconds to 1 minute. The pilot light should stay lit.
Safety Precautions
When dealing with pilot lights, it’s essential to follow proper safety precautions to avoid accidents and injuries:
• Turn off the gas supply: Always turn off the gas supply before attempting to relight the pilot light.
• Use protective gear: Wear protective gear, such as gloves and safety glasses, when working with pilot lights.
• Avoid ignition sources: Avoid using lighters, matches, or other ignition sources near the pilot light.
• Keep the area well-ventilated: Keep the area well-ventilated to prevent the buildup of gas.
Conclusion
A pilot light going out can cause a variety of issues, including reduced performance, incomplete combustion, and even safety hazards. By understanding the common causes of a pilot light going out and following the step-by-step guide to relighting the pilot light, you can ensure your safety and the proper function of your appliance. Remember to follow proper safety precautions and take the necessary steps to relight the pilot light to avoid any potential hazards.
