How to Relight a Heater Pilot
A faulty pilot light on your heater can be frustrating and uncomfortable, especially during the cold winter months. However, relighting a heater pilot is a relatively simple process that you can do yourself with a few tools and some basic knowledge. In this article, we will guide you through the steps to relight your heater pilot and get your heating system up and running again.
Why Is the Pilot Light Out?
Before we dive into the process of relighting the pilot light, it’s essential to understand why the pilot light may be out in the first place. Here are some common reasons:
- Faulty Thermocouple: The thermocouple is a safety device that prevents the pilot light from staying on when the main burner is not lit. If the thermocouple is faulty, it may not allow the pilot light to stay on, causing it to go out.
- Clogged Pilot Orifice: The pilot orifice is a small hole that the pilot light passes through. If it’s clogged, it may prevent the pilot light from staying lit.
- Incorrect Pilot Flame Size: If the pilot flame is too small or too large, it may not be able to keep the thermocouple happy, causing the pilot light to go out.
- Gas Supply Issues: If the gas supply is interrupted or restricted, the pilot light may not stay lit.
Step-by-Step Guide to Relighting the Pilot Light
Relighting the pilot light is a relatively simple process that requires a few tools and some basic knowledge. Here’s a step-by-step guide to help you get your heater pilot relit:
Step 1: Turn Off the Gas Supply
Before attempting to relight the pilot light, make sure to turn off the gas supply to the heater. This is an important safety precaution to prevent any accidents or injuries.
Step 2: Remove the Access Panel
Most heaters have an access panel that can be removed to access the pilot light assembly. Use a screwdriver or nut driver to remove the screws or nuts that hold the panel in place. Be careful not to damage the panel or any other components.
Step 3: Locate the Pilot Light Assembly
Once the access panel is removed, you should be able to see the pilot light assembly. It’s usually located at the bottom or side of the heater.
Step 4: Remove the Pilot Light
Use a wrench or pliers to loosen the nut that holds the pilot light in place. Do not remove the nut entirely, as you’ll need to be able to turn the pilot light later. Gently pull the pilot light out of its holder.
Step 5: Clean the Pilot Orifice
Use a soft brush or cloth to clean out any debris or buildup from the pilot orifice. This will help ensure that the pilot light is able to pass through the orifice freely.
Step 6: Adjust the Pilot Flame Size
Use a screwdriver to adjust the pilot flame size. Make sure the flame is the correct size for your heater. You can refer to your heater’s manual for guidance on the correct flame size.
Step 7: Replace the Pilot Light
Once you’ve cleaned the pilot orifice and adjusted the pilot flame size, you can replace the pilot light. Make sure it’s securely seated in its holder and the nut is tightened in place.
Step 8: Light the Pilot Light
Use a long match or lighter to light the pilot light. Hold the match or lighter to the pilot light for a few seconds to ensure it stays lit.
Step 9: Turn On the Gas Supply
Once the pilot light is lit, you can turn on the gas supply to the heater.
Troubleshooting Common Issues
If you encounter any issues while attempting to relight the pilot light, here are some common troubleshooting tips:
- Pilot Light Won’t Stay Lit: Check the thermocouple to make sure it’s not faulty. You can also try adjusting the pilot flame size.
- Pilot Light Won’t Light: Check the pilot orifice for debris or buildup. You can also try cleaning the pilot light assembly.
- Pilot Light Flickers or Goes Out Frequently: Check the gas supply to ensure it’s not interrupted or restricted.
Conclusion
Relighting a heater pilot is a relatively simple process that requires some basic knowledge and a few tools. By following the steps outlined in this article, you should be able to relight your heater pilot and get your heating system up and running again. Remember to always turn off the gas supply before attempting to relight the pilot light, and to follow the manufacturer’s instructions for your specific heater model.
