A Rheem water heater pilot light that keeps going out often indicates a problem with the thermocouple or pilot tube. Inspecting these components can help identify and fix the issue.
A persistent pilot light issue in Rheem water heaters is a common problem for many homeowners. The thermocouple, a safety device, might be faulty or misaligned, causing the pilot light to extinguish. Dirt and debris in the pilot tube can also block the gas flow, leading to a similar problem.
Regular maintenance and cleaning can often prevent these issues. Ignoring these signs can lead to bigger problems, including a complete shutdown of your water heater. Addressing the problem promptly ensures continuous hot water supply and prevents further damage to the heater.

Common Causes
Rheem water heater pilot issues often stem from a faulty thermocouple, a blocked pilot tube, or insufficient gas supply. Regular maintenance and timely checks can help prevent these common problems.
Thermocouple Issues
The thermocouple is a safety device. It senses if the pilot light is on. Dirt or damage can affect it. A dirty thermocouple may not work right. Cleaning might fix the problem. If it’s damaged, replacing it is best. A weak thermocouple can cause the pilot light to go out. Make sure it is securely connected and in good condition.
Pilot Tube Blockages
The pilot tube delivers gas to the pilot light. Blockages can stop gas flow. Dust and debris can clog the tube. A blocked pilot tube means the pilot light won’t stay lit. Using a thin wire can help clean the tube. Ensure the gas flows freely after cleaning. Regular maintenance can prevent blockages.
Safety Precautions
Always turn off the gas supply before starting any work. This prevents gas leaks and potential hazards. Locate the gas valve on your water heater. Turn it to the off position. This step ensures safety while troubleshooting.
Ensure proper ventilation in the area where the water heater is installed. Good ventilation helps to prevent gas buildup. Open windows and doors to allow fresh air. Clear any obstructions around the vents. Proper ventilation ensures safe operation.
Thermocouple Inspection
A faulty thermocouple can cause the pilot light to go out. Check if the thermocouple is bent or broken. A damaged thermocouple will not work properly. Ensure the thermocouple tip is in the pilot flame. It should glow red when the flame is on. If it doesn’t, it might be faulty.
First, turn off the gas supply to the heater. Carefully remove the old thermocouple from its holder. Install the new thermocouple in the same position. Make sure it is secure and correctly positioned. Turn the gas supply back on and light the pilot. Observe the pilot light to ensure it stays lit. If the pilot stays on, the replacement was successful.
Cleaning The Pilot Tube
Cleaning the pilot tube of your Rheem water heater can resolve issues with the pilot light going out. Regular maintenance ensures consistent operation and prevents unwanted interruptions in hot water supply.
Tools Needed
You will need a few tools for this job. Gather a wrench, a needle, and a soft brush. A flashlight will help you see clearly. Make sure you have gloves to protect your hands. Keep a small container for any loose parts. You may also need a vacuum cleaner.
Step-by-step Guide
First, turn off the gas supply. Locate the pilot tube and remove it with a wrench. Use a needle to clear any blockages. Insert the needle gently to avoid damage. Brush the tube with a soft brush. Make sure to remove all dirt and debris. Use a flashlight to check for any remaining blockages. Reattach the pilot tube carefully. Turn on the gas supply and check if the pilot light stays on.
Gas Supply Issues
Low gas pressure can make the pilot light go out. Use a gauge to check the gas pressure. It should match the manufacturer’s recommendation. If the pressure is too low, contact your gas company. They might need to adjust the supply.
A damaged gas line can cause problems. Look for any leaks or kinks in the gas line. Turn off the gas supply before inspecting. If you find any issues, call a professional immediately.

Ventilation Concerns
Ventilation issues often cause the pilot light on a Rheem water heater to keep going out. Ensuring proper airflow can prevent frequent outages.
Proper Airflow
Good airflow helps the pilot light stay on. Fresh air is important. Keep vents open and clean. Don’t block the area around the heater. Make sure windows or vents near the heater are not shut.
Clearing Obstructions
Remove any items blocking the heater. Check for dust and dirt. Clean the area often. Make sure the air can move freely. This helps the pilot light stay lit.
Burner Assembly Maintenance
Turn off the gas supply. Remove the burner assembly carefully. Use a soft brush to clean the burner. Ensure all dirt and debris are removed. Check for any blockages in the burner ports. Use compressed air to blow out any remaining debris. Inspect the burner for damage or wear. Replace the burner if it is damaged.
Place the burner back into its position. Secure it with screws or clips. Reconnect any detached wires. Ensure all connections are tight. Turn the gas supply back on. Test the burner to ensure it is working properly. Observe the flame to make sure it is steady.
