How to Relight Pilot Light on A.O. Smith Water Heater: A Step-by-Step Guide
A.O. Smith water heaters are widely used in many homes across the world, and they require regular maintenance to function efficiently. One of the most common issues that users face is a blown pilot light, which can be a nuisance and cause inconvenience. In this article, we will provide a step-by-step guide on how to relight the pilot light on an A.O. Smith water heater.
What is the Pilot Light?
The pilot light is a small flame that ignites the burner in your water heater. It is usually located at the bottom of the tank and is responsible for providing the heat needed to warm up the water. If the pilot light goes out, the water heater will not be able to heat up the water, resulting in a lack of hot water supply.
Causes of a Blown Pilot Light
There are several reasons why the pilot light may go out on your A.O. Smith water heater. Some of the common causes include:
• Dirty or clogged pilot orifice: Over time, the pilot orifice can become dirty or clogged with debris, preventing the pilot light from igniting properly.
• Incorrect pilot gas pressure: If the pilot gas pressure is not set correctly, it can cause the pilot light to blow out.
• Improperly adjusted thermostat: If the thermostat is not adjusted correctly, it can cause the pilot light to blow out.
• Leaks in the system: Leaks in the water heater or gas line can cause the pilot light to blow out.
How to Relight the Pilot Light on an A.O. Smith Water Heater
Relighting the pilot light on an A.O. Smith water heater is a relatively simple process that requires some basic tools and a few steps. Here is a step-by-step guide:
Step 1: Turn off the Gas Supply
Before you start relighting the pilot light, make sure to turn off the gas supply to the water heater. This can usually be done by locating the gas shut-off valve and turning it clockwise until it stops. This will prevent any gas leaks and ensure your safety while working on the water heater.
Step 2: Open the Access Panel
Locate the access panel on the side of the water heater and open it by removing the screws or clips that hold it in place. This will give you access to the pilot light and other components of the water heater.
Step 3: Check the Pilot Orifice
Use a small brush or cloth to clean the pilot orifice and make sure it is free of debris. This will ensure that the pilot light ignites properly.
Step 4: Light the Pilot Light
Hold a lit match or lighter to the pilot orifice and gently blow on the orifice to ensure the flame is steady and not flickering. You can also use a pilot light igniter tool, which is available at most hardware stores.
Step 5: Adjust the Pilot Gas Pressure
Use a gas pressure gauge to adjust the pilot gas pressure to the recommended setting. The recommended setting can be found in the user manual or on the manufacturer’s website.
Step 6: Turn on the Gas Supply
Once the pilot light is lit and the pilot gas pressure is adjusted, turn on the gas supply to the water heater. You should hear a faint humming noise when the gas supply is turned on.
Step 7: Check the Pilot Light
Use a flashlight or torch to check the pilot light and make sure it is burning steadily. If it is not, repeat the process until it is.
Additional Tips and Troubleshooting
Here are some additional tips and troubleshooting steps to help you relight the pilot light on your A.O. Smith water heater:
• Make sure the pilot orifice is clean: If the pilot orifice is dirty or clogged, it can prevent the pilot light from igniting properly.
