Common Issues with AO Smith Water Heaters
AO Smith water heaters often face issues that prevent them from staying lit. Recognizing the symptoms and potential causes can streamline troubleshooting and repair.
Symptoms of Heater Not Staying Lit
You’ll notice several signs when your water heater fails to stay lit:

Potential Causes of the Issue
Understanding the reasons behind these symptoms helps in addressing the problem effectively:
- Dirty Burner Assembly: Dirt or debris may obstruct the burner, preventing proper operation.
- Faulty Thermocouple: A defective thermocouple fails to sense the pilot flame, causing the gas valve to shut off.
- Clogged Venting System: Blockages in the vent lines may disrupt airflow, leading to safety shutoffs.
- Gas Supply Issues: Insufficient gas supply or a closed valve impedes the heating process.
- Overheating: High temperatures can trigger safety mechanisms that shut off the burner.
These details clarify the common issues associated with AO Smith water heaters, equipping you with actionable insights for troubleshooting.
Troubleshooting Steps
If your A.O. Smith water heater isn’t staying lit, follow these troubleshooting steps to resolve the issue effectively.
Checking the Thermocouple
Check the thermocouple, a safety device that sense pilot flame. If it’s dirty or malfunctioning, it may shut off the gas. Remove the thermocouple and clean it with a soft cloth. If it appears damaged, replace it. Ensure it’s positioned correctly near the pilot flame for optimal performance.
Inspecting the Gas Supply
Inspect the gas supply to the water heater. Verify the gas valve is open, allowing gas to flow. Listen for any hissing sounds, indicating a leak. If you suspect a leak, refrain from using the heater and contact a professional immediately. Check for blockages in the supply line that could restrict gas flow.
Cleaning the Burner Assembly
Clean the burner assembly to remove dust, debris, or corrosion that might affect the flame. Turn off the gas and remove the access panel. Use a soft brush or vacuum to clean the burner area. Ensure all openings are clear. Once clean, reassemble the parts and test the heater to see if it stays lit.
