Where To Find Pilot Light On Water Heater: Essential Guide!


Debarghya Roy

Locating the pilot light on a water heater can be tricky. It’s usually situated near the gas line at the base of the unit. You may not be able to see the flame, though – newer models may have safety measures like an electronic ignition or sealed combustion chamber. The knob or button labeled “pilot” is where you can access and control it.

My own experience with a faulty pilot light was an eye-opener. One winter morning, I had cold showers because my pilot light had gone out overnight. Despite checking the gas supply and trying to re-ignite it multiple times, nothing worked. So I called a professional plumber who diagnosed a faulty thermocouple. After replacing it, my hot water was restored in minutes.

Remember, dealing with gas components can be dangerous. If you suspect any issues with your water heater’s pilot light, it’s best to seek professional help.

The pilot light on a water heater


The pilot light on a water heater can be in many places, depending on the type and model. It’s usually near the bottom, behind a panel. Look for a small window or a shield. If you need help, use a flashlight.

Be careful: if there’s a gas leak, get out of the area and call the gas company or a plumber.

To start, turn off the gas control valve. Wait a few minutes for any gas to clear. Carefully take off the panel covering the pilot light.

Look for a steady blue flame; this means all is good. But if it’s orange or yellow, or flickers or goes out, there may be an issue. It could be the thermocouple, gas control valve, air in the gas line, or other components.

Don’t wait to deal with any problems. You don’t want issues with hot water, energy efficiency, or safety (like carbon monoxide). Sometimes a DIY fix is enough, but for complex problems, hire a pro.

Check your water heater’s pilot light regularly and do any necessary maintenance. This way you can keep it working and safe!
