If your water heater has suddenly stopped producing hot water, one possible culprit could be a pilot light that has gone out. But before you rush to call a repair technician, have you ever wondered where the pilot light on a water heater is located? Is it hidden somewhere deep inside or easily accessible?

The location of the pilot light on a water heater is a mystery for many homeowners. We often overlook this vital component until it stops working. So, let's uncover the truth and find out exactly where you can find the pilot light on your water heater.

Key Takeaways:

  • The pilot light on a water heater is typically found at the base of the heater, below the gas control valve and behind an access panel.
  • It can be identified by the presence of two small gas lines connected to it.
  • Relighting the pilot light can be done manually with a flame or electronically with the press of a button.
  • Always follow safety precautions and consider contacting a professional if you encounter any difficulties.
  • Knowing the location of the pilot light is crucial for troubleshooting and ensuring your water heater functions efficiently.

How to Relight the Pilot Light on a Water Heater

To relight the pilot light on your water heater, follow these steps:

  1. Turn off the gas on your water heater.
  2. Allow any residual gas to dissipate for 10 minutes.
  3. Using a flashlight, locate the rectangular access panel on the water heater.
  4. Remove the access panel with a screwdriver.
  5. Inside, you will find the pilot light.
  6. On the gas control valve, turn the knob to the “Pilot” position.
  7. Press down on the knob to send gas to the pilot light.
  8. For manual lighting, hold a lit barbecue lighter up to the pilot while continuing to hold down the knob until it ignites.
  9. For electronic ignition, press down on the knob while repeatedly pressing the igniter button until the indicator light turns on.
  10. After the pilot is lit, continue holding down the knob for 90 seconds to clear the air out of the gas line and ensure the pilot stays lit.
  11. Test the pilot light to make sure it doesn't go out before turning the gas back on.

It is important to note that if you have any concerns or difficulties in relighting the pilot light, it is recommended to contact a professional for assistance.

Signs and Causes of a Pilot Light Going Out

There are several signs that indicate water heater pilot light problems, including:

  • No hot water
  • Blinking indicator lights on the gas control valve
  • Absence of a visible flame

A pilot light can go out due to various reasons, such as:

  • Changes in gas pressure
  • Dirty or bent thermocouple
  • Insufficient combustible air
  • Drafts

The thermocouple is a safety device that shuts down the gas valve if the pilot light goes out. If the thermocouple is dirty or bent, it may cause the pilot light to go out repeatedly. Gas pressure changes can also extinguish the pilot light, although this is not a common problem. Lack of combustible air or drafts can also be factors.

If you encounter water heater pilot light problems and the pilot light continues to go out after relighting, it is recommended to contact a professional for further troubleshooting. They can identify the underlying cause of the issue and provide the necessary solutions to ensure your water heater operates reliably.

How to Troubleshoot Pilot Light Problems

If you're experiencing issues with the pilot light on your water heater, there are troubleshooting steps you can take to resolve the problem before seeking professional help. By following these steps, you can potentially save time and money in repairs.

1. Check the Position and Cleanliness of the Pilot Light

Start by ensuring that the pilot light is properly positioned and free from any dirt or debris. Sometimes, a misaligned or dirty pilot light can prevent it from staying lit. Use a flashlight to carefully inspect the pilot light and clean it if necessary.

2. Inspect and Clean the Thermocouple

A dirty or bent thermocouple can also cause pilot light issues. The thermocouple is a safety device that detects whether the pilot light is lit and allows gas to flow to the burner. Over time, it can accumulate dirt or become bent, resulting in pilot light failure. Carefully clean the thermocouple using a soft cloth or replace it if needed.

3. Perform Regular Water Heater Maintenance

Regular maintenance is essential to prevent pilot light problems. Dust and debris can accumulate in the burner and other components, obstructing the flow of gas and affecting the pilot light. Clean out any dust or debris from the burner area and inspect all components for any signs of wear or damage.

4. Seek Professional Assistance

If the pilot light continues to go out or you suspect other issues with your gas line or flame sensor, it is recommended to contact a qualified HVAC technician for further assistance. They have the expertise to diagnose and resolve complex issues with your water heater.
