The Richmond gas water heater pilot won’t stay lit due to a faulty thermocouple or a blocked pilot tube. Replacing or cleaning these components can resolve the issue.
A malfunctioning water heater pilot can be frustrating, especially when hot water is essential for daily tasks. The Richmond gas water heater is known for its reliability, but even the best appliances can face problems. When the pilot light refuses to stay lit, it usually points to common issues that are easy to diagnose and fix.
Typically, a faulty thermocouple or a blocked pilot tube is to blame. Addressing these problems promptly ensures your water heater operates efficiently, providing you with a consistent supply of hot water. Regular maintenance can also prevent such issues, extending the lifespan of your appliance.

Common Causes
Faulty thermocouples, clogged pilot orifices, and gas supply issues often cause Richmond gas water heaters’ pilot lights to go out. Ensuring proper maintenance can help prevent these common problems.
Thermocouple Issues
The thermocouple is a safety device. It senses if the pilot light is on. A dirty or bent thermocouple can stop the pilot from staying lit. Cleaning or straightening it may help. Sometimes, the thermocouple needs to be replaced.
Pilot Tube Blockages
The pilot tube is a small tube. It supplies gas to the pilot light. Dirt or debris can block it. This stops the gas flow. Using a needle, you can clear the blockages. Be careful when doing this. Make sure the gas is off first.
Faulty Gas Valve
The gas valve controls gas flow. A faulty gas valve can stop the pilot light from staying lit. The valve might need to be replaced. Always check for any gas leaks. Safety first!

Safety Precautions
Ensure safety by turning off the gas supply and inspecting the pilot assembly. Clean or replace faulty components to prevent hazards. Regular maintenance helps keep your Richmond gas water heater functioning properly.
Turn Off Gas Supply
Ensure the gas supply is off before starting any checks. Locate the gas valve near the heater. Turn the valve to the OFF position. This step is crucial for your safety.
Ventilation Check
Proper ventilation is needed for the heater to work well. Check that vents are clear of any blockages. Blocked vents can cause dangerous fumes to build up. Always keep the area around the heater clean and free from clutter.
Initial Inspection
Ensure the pilot light is visible. Look for a small blue flame. If you see no flame, the pilot light is out. Check the thermocouple for dirt or damage. Clean it gently if needed. A blocked or dirty thermocouple can cause issues. Make sure the gas valve is in the correct position. It should be set to “Pilot”.
Always smell for gas before doing any work. A gas leak smells like rotten eggs. If you smell gas, turn off the gas supply. Do not light any flames or use electrical devices. Call a professional right away if you detect a gas leak. Safety is the top priority in these situations. Ensure proper ventilation if you sense gas.
Thermocouple Testing
A faulty thermocouple often causes the Richmond gas water heater pilot to extinguish. Testing the thermocouple ensures reliable pilot operation and consistent hot water.
Multimeter Use
A multimeter helps in testing the thermocouple. Set the multimeter to millivolts. Attach one probe to the thermocouple’s tip and the other to the copper part. Light the pilot. The multimeter should read between 25 to 30 millivolts. If the reading is lower, the thermocouple is faulty.
Replacing Thermocouple
First, turn off the gas supply. Unscrew the thermocouple from the gas valve and burner. Replace it with a new thermocouple. Ensure the new one is tightened well. Turn the gas supply back on and light the pilot. The new thermocouple should keep the pilot lit.
Cleaning Pilot Tube
A dirty pilot tube often causes the Richmond gas water heater pilot to extinguish frequently. Clean the pilot tube to ensure a steady flame and reliable water heating.
Required Tools
You need a small brush and a thin wire. Also, get a can of compressed air. A flashlight will help you see better. Gather a wrench and a screwdriver.
Cleaning Steps
First, turn off the gas supply. Let the heater cool down. Use the wrench to remove the pilot tube. Next, use the thin wire to clean inside the tube. Make sure to remove any blockages. Use the small brush to scrub the outside. Blow compressed air through the tube. This removes any leftover debris. Reattach the pilot tube with the wrench. Turn on the gas supply. Finally, relight the pilot and check if it stays lit.

Gas Valve Examination
Check if the gas valve is properly set. Sometimes, it might need a slight turn. Make sure the knob is in the correct position. A small mistake can stop the pilot from staying lit. Always ensure the valve is not blocked. Dust or dirt can cause issues. Cleaning the valve might help.
If the valve is faulty, it must be replaced. Turn off the gas supply first. Remove the old valve carefully. Install the new valve properly. Double-check the connections. Leaks can be dangerous. Test the new valve to ensure it works. Follow the manufacturer’s instructions strictly.
Reigniting Pilot Light
First, turn off the gas supply to the heater. Wait for five minutes to let the gas clear. Next, locate the pilot light and the gas valve. Turn the gas valve to the “Pilot” position. Press and hold the reset button. Use a long lighter to ignite the pilot light. Keep holding the reset button for one minute. Release the button and turn the gas valve to “On”. The pilot light should stay lit now.
- Always read the manufacturer’s manual before starting.
- Keep a fire extinguisher nearby for safety.
- Ensure the area is well-ventilated to avoid gas build-up.
- Do not attempt repairs if you smell gas.
- Call a professional if unsure about any step.
When To Call A Professional
Persistent issues with your Richmond gas water heater pilot light may require professional help. Experts can diagnose and fix underlying problems efficiently.
Persistent Issues
If your Richmond gas water heater pilot won’t stay lit, it may be time to call a professional. Persistent issues like this often indicate deeper problems. The pilot light might keep going out even after several attempts to relight it. A professional can diagnose and fix the issue quickly and safely.
Complex Repairs
Complex repairs should always be handled by a professional. Gas appliances can be dangerous if not handled correctly. A professional will ensure that all repairs are done safely and to code. They have the tools and expertise to fix any problems. Don’t risk your safety by trying to fix complex issues yourself.
Conclusion
Fixing a Richmond gas water heater pilot that won’t stay lit is crucial. Regular maintenance can prevent future issues. Always ensure safety measures are in place when troubleshooting. If problems persist, consult a professional. Keeping your water heater in good condition ensures consistent hot water supply.
Stay proactive in addressing any heater issues.
