Preamble
Gas water heaters are a crucial part of many households, providing a hot shower, bathing children, washing laundry, or running appliances. However, sometimes the pilot light fails to stay lit, requiring you to relight it. This article will take you through the step-by-step process of How to turn on water heater pilot light.
Understanding the Pilot Light
Before we delve into the process, let’s understand what the pilot light is and its function. The pilot light is a small flame that sits at the base of a gas water heater, just above the burner. When lit, it ignites the main burner, providing the heat needed to heat the water. The pilot light is usually always burning when the gas water heater is not operating.
Why the Pilot Light Might Go Out
Before we proceed, here are some common reasons the pilot light might go out:
• Faulty thermocouple: Thermocouples are responsible for sensing the pilot light temperature and ensuring it stays lit. A faulty thermocouple can cause the pilot light to go out.
• Dirty or damaged sensors: Soil and grease residue can clog the thermocouple or sensor opening, causing the pilot light to malfunction.
• Improper installation: Malfunctioning pilot lights or poor installation can lead to issues.
• Malfunctioning gas valve: Faulty gas valves prevent the proper flow of gas, leading to pilot light failure.
How to Turn On Water Heater Pilot Light
Now that you’re familiar with the why, let’s get hands-on and learn how to turn on water heater pilot light. These steps will guide you:
Step 1: Locate the Pilot Assembly
Identify the location of the pilot assembly; it’s usually indicated by a diagram on the side of the tank or a rectangular plate on the front with a button or knob marked "pilot" or "gas". You may need to adjust the plate or button until you can access the assembly.
Step 2: Turn Off Power and Gas
Confirm the gas supply is switched off by checking if the valve is in the "off" position and the burner is cool.
Disconnect the power cable if your water heater has an electric ignition sequence. For gas-only control, you can skip this step.
Step 3: Light the Pilot Light
- Locate the striker wheel (black cylinder shaped burner), usually at the base of the pilot orifice. Hold the tankless light or match a few inches away from this wheel.
- Press and hold the strike button or knob.
- Light the pilot with the tankless light or match at the base of the tank, holding it until it ignites.
- Hold the pilot until it is lit and keep the striker wheel pressed in until the pilot’s flame reaches the thermocouple. This should produce a strong, steady fire.
Step 4: Adjust the Thermostat and Pilot Light Combination
Adjust the thermostat while holding the pilot light: Increase the temperature for 30 seconds if pilot ignites first . If pilot doesn’t want to stay lit, there might be an issue (check sensors, thermocouple, or gas line leaks).
Step 5: Turn on Power and Gas
Reverse the power and gas isolation steps. Confirm all connections are secure after relighting the pilot:
- Ensure the power cables are properly connected.
- Check that the gas control valve is in the ‘on’ position.

| Issue | Possible Causes | Solution |
|---|---|---|
| Pilot won’t stay lit | Faulty thermocouple, clean sensors | Replace thermocouple, clean sensors |
Additional Tips for Pilot Light Maintenance
Consider these best practices to help prevent pilot light issues and extend your water heater’s lifespan:
• Insulate your water heater’s flue to preserve heat and reduce energy bills.
• Regularly clean your water heater sensors using a wire scrubber and a small bristled brush.
• Inspect your gas line, looking for signs of water damage, rust, or corrosion.
• Tighten loose connections: Regularly check and securely fasten all gas piping, water heater connections, and other components.
Summary
Turning on a water heater pilot light is crucial for your household’s hygiene and convenience. By identifying common causes of pilot outages, understanding the ignition process, and following straightforward steps, you can solve this common issue. When you need to relight your water heater pilot light, refer to this detailed guide, and don’t hesitate to consult a licensed plumber if you encounter trouble.
