Troubleshooting Guide: How to Reset Your Gas Water Heater Pilot Light When It’s Out

Resetting the pilot light on a gas water heater is a common task that can be easily performed by homeowners. By following these step-by-step instructions, you can safely and effectively relight your pilot light and restore hot water to your home.

Understanding the Pilot Light

The pilot light is a small flame that continuously burns in your water heater to ignite the main burner when hot water is needed. If the pilot light goes out, the water heater will not be able to heat water.

When to Reset the Pilot Light

There are several reasons why a pilot light may go out, including:

• Drafts or wind
• Power outages
• Gas supply interruptions
• Sediment buildup

Safety Precautions

Before you begin, it’s important to take the following safety precautions:

• Turn off the gas supply to the water heater.
• Allow the water heater to cool for at least 30 minutes before attempting to reset the pilot light.
• Keep all flammable materials away from the water heater.

Step-by-Step Instructions

1. Locate the Pilot Assembly

The pilot assembly is typically located at the bottom of the water heater. It consists of a control knob, a burner tube, and a pilot light.

2. Turn Off the Gas Supply

Use the gas valve located on the gas line to turn off the gas supply to the water heater.

3. Wait for the Water Heater to Cool

Allow the water heater to cool for at least 30 minutes before attempting to reset the pilot light. This will prevent the gas from igniting prematurely.

4. Remove the Pilot Assembly

Use a screwdriver to remove the screws holding the pilot assembly in place. Gently pull the assembly out of the water heater.

5. Clean the Pilot Assembly

Use a wire brush to clean the burner tube and pilot light. Remove any dirt or debris that may have accumulated.

6. Reassemble the Pilot Assembly

Once the pilot assembly is clean, reinsert it into the water heater and tighten the screws.

7. Turn on the Gas Supply

Slowly turn on the gas valve to allow gas to flow into the water heater.

8. Light the Pilot Light

Use a long-reach lighter to light the pilot light. Hold the lighter near the pilot light and press the ignition button.

9. Adjust the Flame

Once the pilot light is lit, adjust the flame to a small, blue flame.

10. Turn on the Water Heater

Turn the gas valve to the “on” position to allow gas to flow to the main burner.

Troubleshooting

If you are having trouble resetting the pilot light, here are some troubleshooting tips:

• Check the gas supply: Make sure that the gas valve is turned on and that there is gas flowing to the water heater.
• Clean the pilot assembly: Dirt or debris can block the pilot light from igniting. Clean the burner tube and pilot light thoroughly.
• Check the thermocouple: The thermocouple is a safety device that shuts off the gas supply if the pilot light goes out. If the thermocouple is faulty, it will need to be replaced.
• Call a professional: If you are unable to reset the pilot light yourself, call a qualified plumber for assistance.

The Bottom Line: Restoring Hot Water in Minutes

By following these step-by-step instructions, you can safely and effectively reset the pilot light on your gas water heater. This will restore hot water to your home and ensure that you have a comfortable and convenient water heating system.
