How to Check Pilot Light on Water Heater
To check the pilot light on your water heater, first locate the pilot light assembly behind the access panel near the bottom. Make sure the area is well-ventilated and the gas is off for safety. Look through the viewing window for a steady, blue flame—this means it’s working properly. If the flame is weak, flickering, or out, you may need to relight it following safety steps. Keep going to understand how to safely manage the pilot light and when to call a pro.
Locate the Pilot Light Assembly
Before you check the pilot light, you need to locate the pilot light assembly on your water heater. Typically, this assembly sits near the bottom of the unit, behind a removable access panel. You’ll likely find a small door or cover secured with screws or clips. Remove it carefully to expose the control valve, thermocouple, and pilot burner.
The pilot light assembly includes a small tube where the flame burns continuously to ignite the main burner when needed. If you have a gas water heater, the assembly should be near the gas control knob, often labeled “Pilot” or “Igniter.”
Identifying this area correctly ensures you’re checking the right component, making the troubleshooting process straightforward and effective.
Ensure Safety Precautions Are in Place
Now that you’ve located the pilot light assembly, take a moment to prepare your workspace for a safe inspection. First, ensure the area is well-ventilated to prevent gas buildup. Open nearby windows or doors if possible.
Next, turn off the gas supply to the water heater to avoid accidental ignition. Make sure there are no flammable materials close by—clear away any papers, cleaning supplies, or fabrics.
Use a flashlight instead of matches or lighters for visibility. Wear safety gloves and goggles to protect yourself from heat or debris.
Finally, double-check that your tools are in good condition and within reach. Following these precautions helps you stay safe while inspecting the pilot light without risking injury or damage.
Inspect the Pilot Light Status
Once you’ve prepared your workspace, you can check the pilot light to see if it’s lit. Locate the access panel or window on your water heater, usually near the bottom. Look through the viewing window or open the panel carefully to spot the pilot light.
You’re looking for a small, steady blue flame with a hint of yellow at the tip. If the flame is steady and blue, your pilot light is functioning properly. A flickering, weak, or predominantly yellow flame can indicate a problem like dirt buildup or incomplete combustion.
If you don’t see any flame at all, the pilot light is out. Remember, don’t try to relight it yet—that comes next. Just focus on accurately assessing its current status.
Relight the Pilot Light if Necessary
If your pilot light is out, you’ll need to relight it to restore your water heater’s function. First, turn off the gas supply valve and wait five minutes to let any residual gas dissipate.
Locate the pilot light assembly, usually near the bottom of the heater. Turn the gas control knob to the “pilot” position.
While pressing the knob down, use a long lighter or match to ignite the pilot light. Keep holding the knob for about 30 seconds after the flame catches to ensure the thermocouple heats up and signals the gas valve to stay open.
Slowly release the knob and check that the pilot light remains lit. Finally, turn the gas control back to the “on” position, and your water heater should start functioning normally.
When to Call a Professional Technician
Although relighting the pilot light is a straightforward task, you should call a professional technician when you encounter persistent issues, unusual smells, or if the pilot light won’t stay lit despite your efforts.
If you notice a strong gas odor, turn off the gas supply immediately and contact an expert to prevent hazardous leaks.
Also, if the pilot light repeatedly goes out or won’t ignite after several attempts, it could indicate a deeper problem with the thermocouple, gas valve, or ventilation.
Attempting complex repairs without proper knowledge can be dangerous. Trust a licensed technician to diagnose and fix these issues safely, ensuring your water heater operates efficiently and your home stays secure.
Don’t hesitate to seek professional help when you’re unsure or face ongoing problems.
Frequently Asked Questions
What Causes a Pilot Light to Keep Going Out Frequently?
A pilot light keeps going out frequently because you’ve got a dirty pilot tube, a faulty thermocouple, or a draft blowing it out. You’ll want to clean parts, check connections, and fix any drafts to solve this.
Can a Water Heater Operate Without a Pilot Light?
No, your water heater can’t operate without a pilot light if it uses a standing pilot ignition system. The pilot light ignites the burner, so without it, your heater won’t produce hot water.
How Much Gas Does a Pilot Light Consume Annually?
You’ll use about 600 to 1,000 cubic feet of gas annually for a pilot light. It’s a small amount, but turning it off when not needed can save you money and energy over time.
Are There Electronic Alternatives to Pilot Lights?
Yes, you can use electronic ignition systems instead of pilot lights. They only ignite the burner when needed, saving gas and improving safety. You’ll find these in newer water heater models or as upgrade options.
How Do Pilot Light Issues Affect Water Heater Efficiency?
Pilot light issues decrease your water heater’s efficiency because a weak or flickering flame wastes fuel and may cause inconsistent heating. If it goes out, your water won’t heat, forcing you to relight it promptly.
Conclusion
Now that you know how to check your water heater’s pilot light, you can handle this simple task with confidence. Always prioritize safety by turning off the gas and ensuring proper ventilation before inspecting. If the pilot light is out, follow the steps to relight it carefully. However, if you encounter any issues or feel unsure, don’t hesitate to call a professional technician. Staying cautious keeps you and your home safe.
