Rheem water heater not staying lit could be due to a faulty thermocouple or a clogged pilot tube. Address these issues promptly to restore functionality.
A water heater that won’t stay lit can be frustrating and inconvenient, especially in colder months. One common culprit is a malfunctioning thermocouple, which fails to detect the pilot flame, causing the gas valve to shut off. Another frequent issue is a clogged pilot tube, which restricts gas flow to the pilot light.
Regular maintenance and timely repairs can prevent these problems. Understanding these potential issues allows for quicker diagnosis and resolution, ensuring your Rheem water heater operates efficiently. Proper care not only extends the heater’s lifespan but also enhances home comfort.

Common Causes
The pilot light can get dirty or clogged. Dirt can block the gas flow. Clean it with a needle or a thin wire. The gas valve might not be open. Make sure it is fully turned on. Wind can blow out the light. Shield the heater from drafts. A faulty thermocouple can also cause issues.
The thermocouple senses the pilot light. If it is dirty, it may not work. Clean it with a soft cloth. A loose thermocouple connection can be a problem. Tighten the connection with a wrench. A bent thermocouple might not detect heat. Straighten it carefully. Sometimes, replacing the thermocouple is the best solution.
Pilot Light Troubleshooting
Turn off the gas supply to the water heater. Wait for five minutes to clear any gas. Locate the pilot light assembly near the bottom of the heater. Set the gas valve to the “pilot” position. Press and hold the pilot button. Use a lighter or match to ignite the pilot light. Hold the button for 60 seconds after lighting. Release the button slowly. The pilot light should stay lit.
Check for any dirt or debris around the pilot assembly. Clean the area with a soft brush. Ensure the flame is blue and steady. If the flame is yellow or flickering, adjust the flame. Look for any signs of wear on the thermocouple. Replace if it looks damaged. Make sure all connections are tight. Inspect the gas line for any leaks. Fix any issues found.
Thermocouple Checks
Experiencing issues with your Rheem water heater not staying lit? Thermocouple checks can help identify if this crucial component needs replacement, ensuring continuous operation. Regular maintenance keeps your heater functioning efficiently.
Cleaning The Thermocouple
The thermocouple may get dirty. Dirt can block the heat signal. Use a sandpaper to clean it. Rub it gently to remove dirt. Be careful not to bend it. Check if it is in the right place. It should be close to the pilot flame. Clean thermocouple helps in keeping the heater lit.
Replacing The Thermocouple
A broken thermocouple won’t work. You need a new one. Turn off the gas first. Unscrew the old thermocouple. Take it out carefully. Put the new one in the same place. Screw it tightly. Turn the gas back on. Check if the pilot light stays lit.

Gas Supply Problems
Make sure the gas line is turned on. Look for any kinks or blockages in the line. Ensure the gas line is connected securely. Listen for any hissing sounds which might indicate a leak. Smell for gas odor which can mean a leak. If you find any issues, contact a professional immediately.
Check the gas valve to ensure it is open. The valve should be in line with the pipe. Make sure the valve is not clogged. Clean it if necessary. Ensure the gas valve is not damaged. Replace it if you find any damage. Proper functioning of the gas valve is crucial for the heater.
Ventilation Issues
A blocked vent can cause your Rheem water heater to shut off. Make sure no debris is blocking the vent. Bird nests and leaves are common culprits. Check the vent pipe for any obstructions. Use a small brush to clear out any dirt or debris. This helps the heater stay lit.
Proper venting is crucial for your water heater. The vent pipe should be the right size and length. A pipe that is too small or too long can cause issues. Make sure the vent pipe is securely connected. Leaks in the pipe can cause the heater to shut off. Ensure the vent pipe has no bends or kinks. This will help the heater work efficiently.
Flame Sensor Examination
The flame sensor can get dirty. Dirt stops it from working well. Clean it with a soft cloth. Be gentle to avoid damage. A clean sensor helps the heater stay lit. Use a mild cleaner if needed. Make sure it is dry before re-installing.
Use a multimeter to test the flame sensor. Set the multimeter to measure ohms. Touch the sensor’s tip with one lead. Place the other lead on the sensor’s base. A good sensor shows low resistance. Replace the sensor if the reading is too high. This ensures the heater works properly.
Electrical Component Inspection
Inspect the wiring for any visible damage or loose connections. Frayed wires can cause the heater to stop working. Use a voltmeter to check if the wires have the correct voltage. Replace any damaged wires to ensure safety. Make sure all connections are tight and secure. Check the wiring diagram for proper connections.
The control board manages the heater’s functions. A faulty control board can prevent the heater from staying lit. Examine the board for any burn marks or damaged components. Use a multimeter to test the control board’s circuits. If the board is defective, it needs to be replaced. Contact a professional if unsure about inspecting the control board.
Professional Help
If the water heater makes strange noises, it needs expert help. No hot water means a technician is required. Frequent shutdowns also signal a need for professional service. Leaking water is another sign to call a technician. Any burning smell is a serious issue. It needs immediate attention from a professional.
Choose a service with good reviews. Ask friends for recommendations. Look for certified technicians. Make sure they offer a warranty. Check their response time. Reliable services are prompt and professional.
