The pilot light on a Rheem water heater can go out due to a faulty thermocouple or dirty pilot tube. Another common cause is a draft.
A persistent pilot light issue can be frustrating and inconvenient. Understanding the reasons behind this problem can help in finding an effective solution. Common causes include a malfunctioning thermocouple, which fails to detect the flame, or a dirty pilot tube that restricts gas flow.
Additionally, drafts or improper venting can extinguish the pilot light. Regular maintenance and timely repairs can ensure your Rheem water heater operates efficiently. Knowing these potential issues can save time and prevent further complications. Always consult a professional if the problem persists.

Common Causes
The thermocouple is a safety device. It senses if the pilot light is on. A dirty or bent thermocouple can cause problems. It might not detect the pilot light. This can cause the light to go out. Sometimes, the thermocouple can get worn out. In such cases, it needs replacement. Always keep it clean and straight. This helps it work properly.
The pilot tube delivers gas to the pilot light. Dust or debris can block this tube. A blocked tube means no gas for the pilot light. The light will go out without gas. Regular cleaning of the pilot tube is important. This ensures a steady gas flow. Check the tube for any blockages often. This simple step can save a lot of trouble.

Safety Precautions
Always turn off the gas supply before working on your water heater. This prevents any gas leaks and potential explosions. Locate the gas valve near the water heater. Turn it to the off position. Wait a few minutes to ensure no gas is flowing.
Proper ventilation is crucial for safety. Make sure the area around the water heater is well-ventilated. Clear away any obstructions. Good airflow helps prevent carbon monoxide buildup. Ensure vents are not blocked. This keeps everyone safe from toxic gases.
Thermocouple Problems
A faulty thermocouple often causes the Rheem water heater pilot light to go out. Replacing or cleaning the thermocouple can solve the issue.
Testing The Thermocouple
The thermocouple checks if the pilot light is on. If the pilot light goes out, the thermocouple stops the gas flow. Use a multimeter to test it. Set the multimeter to millivolts. Place one probe on the thermocouple’s tip. Place the other probe on the thermocouple’s body. Light the pilot light and watch the meter. It should show a reading. If it reads below 20 millivolts, it is bad.
Replacing The Thermocouple
Turn off the gas supply first. Unscrew the thermocouple from the gas control valve. Remove it from the burner assembly. Get a new thermocouple of the same type and length. Attach the new thermocouple to the gas control valve. Secure it to the burner assembly. Turn the gas back on and light the pilot light. The new thermocouple should work well now.

Pilot Tube Cleaning
You will need a few tools. Get a wrench, a small brush, and a cloth. Safety goggles are also important. Cleaning solution or vinegar helps too.
Turn off the gas supply first. Use the wrench to loosen the pilot tube. Carefully remove it. Use the small brush to clean the tube. Make sure to scrub gently. Dip the brush in the cleaning solution. Clean the inside of the tube thoroughly. Rinse the tube with water. Dry it with the cloth. Reattach the tube with the wrench. Turn the gas back on.
Gas Supply Issues
Low gas pressure can cause the pilot light to go out. Use a gauge to check the pressure. It should be within the recommended range. Low pressure might indicate a problem with the gas supply. Contact your gas company for help.
Gas lines must be free of leaks. Leaks can cause the pilot light to go out. Use soapy water to check for leaks. Bubbles will form if there is a leak. Tighten any loose connections. Replace damaged gas lines immediately. Always ensure the gas valve is open fully. A partially closed valve can restrict gas flow.

Draft Problems
Drafts can blow out the pilot light. Check for any open windows or doors near the heater. Feel for cold air around the heater. Use a candle to detect drafts. The flame will flicker if there is a draft. Check the venting system. Blocked or broken vents can cause drafts. Ensure the vent cap is intact and secure. Inspect the flue pipe for any gaps or holes.
Seal any gaps around windows and doors. Use weather stripping to block drafts. Close any windows near the water heater. Ensure the venting system is clear and functional. Install a draft hood if one is not present. This can help direct airflow properly. Regularly inspect and maintain the venting system. This ensures there are no blockages or damage.
Burner And Orifice Cleaning
Cleaning the burner and orifice can resolve issues with a Rheem water heater pilot light that keeps going out. A clean burner ensures efficient combustion and stable pilot light operation.
Cleaning The Burner
The burner must stay clean for the heater to work well. Start by turning off the gas supply. Use a brush to remove dirt from the burner. Pay attention to the small holes on the burner. These holes can get clogged and affect the flame. Clean them gently with a needle. This will help the burner work better.
Inspecting The Orifice
The orifice controls the gas flow to the burner. A dirty orifice can cause problems. Use a flashlight to inspect the orifice. Look for any dirt or debris. If it is dirty, use a soft brush or compressed air to clean it. Make sure not to damage the small hole in the orifice. A clean orifice ensures proper gas flow and keeps the pilot light stable.
When To Call A Professional
If your Rheem water heater pilot light keeps going out, it may need expert help. Frequent pilot light outages indicate a deeper issue. Unusual noises from the heater can be a red flag. Smelling gas around the unit is a serious concern. These signs require quick action to avoid bigger problems.
Always choose a licensed technician for repairs. Check their experience with Rheem water heaters. Read customer reviews to ensure quality service. Ask if they offer a warranty on their work. This ensures your heater will be fixed correctly.
