A Rheem water heater won’t stay lit due to a faulty thermocouple or a clogged pilot tube. Check these components first for issues.
Having a reliable water heater is essential for everyday comfort. Rheem water heaters are known for their durability, but like any appliance, they can encounter problems. One common issue is the pilot light refusing to stay lit. This can be frustrating and inconvenient.
The problem often lies with a malfunctioning thermocouple or a blocked pilot tube. These components play critical roles in maintaining the pilot flame. Understanding their function and how to troubleshoot them can help you restore your water heater’s performance quickly. Let’s dive into some practical steps to fix this issue efficiently.

Common Issues
The pilot light may go out often. This can be due to drafts or clogs. Check for debris around the pilot light. Ensure there is no air flow blowing it out. A dirty orifice can also cause problems. Clean it with a small brush or compressed air.
A faulty thermocouple can cause the heater to shut off. The thermocouple detects if the pilot light is lit. If it fails, the gas valve closes. Inspect the thermocouple for wear or damage. Replace it if necessary. Also, ensure it is properly positioned near the pilot light.

Pilot Light Troubleshooting
First, ensure the gas supply valve is open. Look at the pilot light. Is it lit? If not, the gas supply might be off or interrupted. Turn the gas control knob to “Pilot” and hold it down. Light the pilot with a match or lighter. Continue holding the knob for 30 seconds. Release it slowly and see if the pilot stays lit. If it goes out, the thermocouple might be faulty.
Dirt can clog the pilot orifice. Turn off the gas supply. Use a small brush or compressed air to clean the orifice. Make sure no debris is left behind. A clean orifice allows the pilot to stay lit. Reassemble the parts and turn the gas back on. Light the pilot and check if it stays lit. Repeat cleaning if necessary.
Thermocouple Inspection
A multimeter helps test a thermocouple. Set the multimeter to millivolts. Place one probe on the thermocouple’s tip. Put the other probe on the copper tube. Light the pilot and watch the meter. The reading should be between 25 and 30 millivolts. If it’s lower, the thermocouple is bad.
First, turn off the gas supply. Remove the burner assembly. Unscrew the old thermocouple from the gas valve. Take out the thermocouple from the bracket. Insert the new thermocouple into the bracket. Attach it to the gas valve. Reassemble the burner and turn the gas back on. Light the pilot to check if it works.

Gas Supply
Check the gas line to your water heater. Ensure it is not blocked. Make sure the gas line is fully open. A blocked gas line can stop the heater from staying lit. Inspect the gas pressure. Low gas pressure can cause problems. You might need a professional to check the gas pressure. Make sure all connections are tight. Loose connections can cause gas leaks.
Turn off the gas supply before inspecting. Check the gas valves for any damage. Replace damaged valves immediately. Ensure the gas valve is in the correct position. Open the gas valve fully. A partially open valve can cause issues. Look for any signs of wear and tear. Worn valves should be replaced.
Ventilation
Proper ventilation is crucial for a Rheem water heater to stay lit. Blocked vents can cause the pilot light to extinguish frequently. Ensure unobstructed airflow to maintain consistent operation.
Clearing Blockages
Blockages in vents can cause your Rheem water heater to fail. Check the vents for any debris or obstructions. Even small items like leaves can be a problem. Use a flashlight to see inside the vent. If you find anything, remove it carefully. Make sure the vents are clear before moving on.
Ensuring Proper Airflow
Proper airflow is key for your water heater. The area around the heater should be clean and uncluttered. Any objects close to the heater can block air. Keep at least two feet of space around it. Also, check if the ventilation system is working well. If the air can’t flow freely, the heater won’t stay lit.

Burner Assembly
The burner may have dust or debris. This can block gas flow. Use a soft brush to clean the burner. Ensure all holes are clear. Be gentle to avoid damage. After cleaning, check if the water heater lights up.
Check the pilot light. Ensure it is steady and blue. Inspect the thermocouple. It should be clean and connected. Look for corrosion or wear. Replace any damaged parts. Ensure the gas valve is open and the gas supply is steady. This will help keep the burner lit.
Temperature Control
Adjust the thermostat to the correct setting. Ensure it is not too low. A low setting can cause the water heater to turn off. Turn the dial slowly. Find the point where the heater stays lit. Monitor the water temperature. Make small adjustments if needed.
Sometimes, the thermostat might be faulty. Replacing it can fix the issue. First, turn off the power. Next, remove the access panel. Find the thermostat and disconnect the wires. Replace it with a new one. Reconnect the wires and secure the panel. Turn on the power and test the heater.
Professional Help
Expert assistance can resolve issues when your Rheem water heater won’t stay lit. Trust experienced professionals to diagnose and fix the problem efficiently.
When To Call A Technician
A technician should be called when basic troubleshooting does not fix the issue. Persistent pilot light problems require professional attention. Gas leaks or strange noises are serious signs. Water heater performance issues also need expert help. Safety concerns should always be a priority. Regular maintenance can prevent many issues.
Cost Estimates
The cost for a technician visit can vary. On average, expect to pay between $100 to $200. Some complex repairs may cost more. Parts replacement adds to the total cost. Always ask for an estimate before work begins. Regular servicing can save money in the long run. Proper maintenance reduces the need for costly repairs.
