A water heater pilot light is a small flame that burns constantly in order to ignite the gas burner within your water heater. This flame may be small, but it plays an important role in ensuring that you have hot water whenever you need it.
However, if this pilot light goes out, your hot water supply will be disrupted until you relight it.
There are several reasons why a water heater pilot light might go out. One of the most common causes is a draft blowing out the flame – this could happen if there’s a window open nearby or if there’s a strong gust of wind outside.
Here are more detailed explanation on water heater pilot light common problems and how to troubleshoot this problems!
Water Heater Pilot Light Common Problems
To troubleshoot the common problems with your water heater pilot light, you need to understand the symptoms and their causes. No worry if you use Tankless Water Heater Maintenance!
Here are some symptoms of troubling water heater pilot light.
1. Water Heater Pilot Light Keeps Going Out
One reason why your pilot light may not stay lit is due to a faulty thermocouple. The thermocouple is a safety device that shuts off the gas supply if it senses that the pilot light has gone out.
If the thermocouple is malfunctioning or dirty, it may not detect the flame and will shut off the gas supply, causing your pilot light to go out.
Another reason could be due to a drafty environment around your water heater where gusts of wind can blow out your pilot light.
2. Pilot Light Not Igniting
One common problem is a clogged pilot tube. Dirt and debris can accumulate in the tube over time and prevent gas from flowing through it. A simple solution to this issue is to clean the tube thoroughly with a needle or wire brush.
Another possible reason for a non-igniting pilot light is a faulty thermocouple. The thermocouple is responsible for sensing if the flame is lit and turning off the gas supply if there’s no flame present.
3. Pilot Light Burning Yellow
A disconcerting problem is the yellow flame of a water heater pilot light. This happens when there’s a blocked oxygen flow to the burner or low gas pressure. It can also be caused by rust, dirt, and other debris, or an incorrect air shutter or dirty thermocouple.
The yellow flame can lead to carbon monoxide poisoning, so it’s best to get an expert to examine and repair the heater.
Don’t try to fix it yourself – call for professional help to avoid further complications.

How do I know if my pilot light is working?
The first thing to check is whether or not there’s a flame present. You can usually see this through a small window on your appliance or by opening up the access panel if there’s no window available. If there’s no flame, then you need to relight it. Follow the manufacturer’s instructions carefully as they will vary depending on your specific appliance model.
Another way to tell if your pilot light is working properly is to check its color and size. A healthy pilot light should have a blue flame that’s steady and strong.
Does the pilot light always stay on?
The answer is no. In most cases, modern gas appliances feature an electronic ignition system that replaces the traditional pilot light.
Instead of continuously burning like a pilot light, this ignition system only sparks when needed to ignite the main burner. This not only saves energy but also eliminates any potential safety hazards associated with having an open flame constantly lit.
Can I manually light my pilot light?
Yes, you can manually relight it yourself. All you need is matches or a lighter and some basic knowledge of how to operate your appliance.
Before attempting to relight your pilot light, make sure that all gas valves are completely turned off and wait at least five minutes to allow any accumulated gas fumes to dissipate.
