The water heater main burner won’t stay lit due to a faulty thermocouple or dirty burner. Both issues can be resolved with proper maintenance.
A water heater is crucial for providing hot water in homes. When the main burner won’t stay lit, it disrupts daily activities and comfort. Common causes include a malfunctioning thermocouple, which fails to detect the pilot light, and a dirty burner, which can block the gas flow.
Addressing these issues promptly can restore your water heater’s functionality. Regular maintenance and timely repairs ensure longevity and efficiency. Understanding these common problems helps homeowners troubleshoot effectively, saving time and money. For persistent issues, consulting a professional plumber is recommended. Proper care can prevent future disruptions and maintain consistent hot water supply.

Common Causes
The gas supply might be interrupted. Check if the gas valve is fully open. Sometimes, low gas pressure can cause problems. Inspect the gas line for any leaks. Ensure there are no blockages in the gas line.
The thermocouple might be dirty or faulty. Clean the thermocouple with sandpaper. Replace it if cleaning does not work. Ensure the thermocouple is properly aligned. The tip should touch the flame. Tighten any loose connections.

Safety First
First, turn off the gas supply to the water heater. Find the main gas valve and switch it off. This step prevents gas leaks and ensures safety. Make sure the area is well-ventilated.
Check the ventilation around your water heater. Clear any obstructions from the vent pipes. Proper ventilation helps in preventing carbon monoxide buildup. Ensure windows or doors are open to allow fresh air.
Inspecting The Thermocouple
When inspecting the thermocouple, ensure it is positioned correctly and free from dirt or debris. Check for any signs of wear or corrosion on the thermocouple itself and the connections. To troubleshoot further, test the thermocouple for proper functionality. Cleaning tips include using a soft cloth to gently wipe away any buildup on the thermocouple. Avoid using harsh chemicals that could damage the component.
Gas Supply Check
Ensure the gas valve is in the correct position. The valve should be fully open. This allows gas to flow to the burner. A partially open valve can cause issues. Check the valve handle and make sure it’s aligned properly.
Inspect the gas supply line for any kinks or damage. A damaged line can cause gas flow problems. Make sure the line is straight and free of obstructions. Look for leaks by smelling for gas. If you smell gas, turn off the supply immediately.
Pilot Light Issues
Ensure the gas supply is on. Turn the gas valve to the “pilot” position. Hold a lit match or lighter near the pilot. Press and hold the reset button. Keep the button pressed for 30 seconds. If the pilot does not stay lit, the thermocouple may need replacing.
Dirt can block the pilot light. Turn off the gas supply first. Use a small brush to clean the assembly. Remove any dust and debris. Ensure the pilot orifice is clear. Reassemble and relight the pilot. This may fix the burner issue.
Burner Assembly Examination
Look closely at the burner assembly. Check for rust and corrosion. These are signs of wear. The burner holes should be clear. Blockages can stop the burner from lighting. Soot around the burner is another sign. This could mean it is burning poorly.
Turn off the gas supply before replacing parts. Use a wrench to loosen the burner. Remove the old burner carefully. Place the new burner in the same spot. Tighten it with the wrench. Turn the gas supply back on. Check if the burner lights up. Safety first: always check for gas leaks.
Professional Help
If your water heater’s main burner won’t stay lit, it might be best to call a pro. A professional can safely handle complex issues. They have the right tools and know-how. Trying to fix it yourself might cause more harm. Professionals can also check for gas leaks. They ensure everything works well and safely. Your safety is very important. Never risk it by trying to fix gas issues alone. Always seek help if unsure.
Hiring a pro can cost money, but it ensures safety. Fixing it yourself may seem cheaper. But mistakes can be expensive. Professionals charge for their time and skills. They also bring their own tools. The cost varies by issue complexity. Simple fixes cost less. Bigger problems might be more expensive. Always get a quote before agreeing to repairs. This helps you plan your budget well.

Preventive Maintenance
Check your water heater every month. Look for any leaks or rust. Make sure the pilot light is on. Listen for any weird noises. Call a professional if you find any problems. They can fix it before it gets worse. Keep a record of your inspections. This helps you remember when you last checked.
Keep the area around your water heater clean. Remove any dust or debris. Clean the burner every six months. Use a soft brush to remove dirt. Check the vent for blockages. Make sure the flame is blue. A yellow flame means a problem. Call a professional if the flame is not blue. Clean the tank once a year. This helps remove sediment and keeps the heater working well.
