If the reading is less than 20 millivolts, the thermocouple is faulty. You will need to replace it.
Replacing A Faulty Thermocouple
Replacing a faulty thermocouple is simple. Here’s how to do it:
- Turn off the gas supply.
- Remove the burner assembly.
- Disconnect the old thermocouple.
- Install the new thermocouple.
- Reassemble the burner and turn on the gas.
Ensure all connections are tight. This will prevent gas leaks.
Water Heating Hiccups
Water heating hiccups can be annoying. They often disrupt daily routines. A common issue is the Ao Smith gas water heater not working properly. Knowing how to troubleshoot can save time and money. Here are two main areas to check.
Adjusting The Thermostat
The thermostat controls the water temperature. Sometimes it’s set too low. Adjusting the thermostat can solve many problems.
Follow these steps:
- Turn off the power to the water heater.
- Locate the thermostat. It’s usually behind a panel.
- Use a screwdriver to adjust the temperature. Turn it to the desired setting.
- Replace the panel and turn the power back on.
Ensure the temperature is set between 120°F and 140°F. This helps in maintaining optimal performance.
Flushing The Tank
Flushing the tank removes sediment build-up. Sediment can affect heating efficiency. Regular flushing keeps the water heater in good condition.
Follow these steps:
- Turn off the gas supply and water supply.
- Connect a hose to the drain valve at the bottom of the tank.
- Place the other end of the hose in a safe drain area.
- Open the drain valve and let the water flow out.
- Close the drain valve once the tank is empty.
- Turn on the water supply and let the tank fill up. Then, turn on the gas supply.
Flushing the tank every six months can prevent many issues.
Burner Issues And Solutions
Experiencing issues with your Ao Smith gas water heater burner can be frustrating. Identifying and fixing these problems ensures your heater works efficiently. This guide covers common burner issues and their solutions.
Cleaning The Burner Assembly
A dirty burner assembly can cause inefficient heating. Regular cleaning prevents this.
Follow these steps to clean the burner assembly:

- Clean any dirt around the ignition system.
- Test the igniter for a strong spark.
Regular maintenance of your Ao Smith gas water heater ensures efficient performance. Clean the burner and check the ignition system often.
Pressure Relief Valve Checks
The pressure relief valve is a critical safety feature in your Ao Smith gas water heater. This valve prevents excessive pressure buildup, which can lead to dangerous situations. Regular pressure relief valve checks ensure your water heater operates safely and efficiently.
Testing Valve Function
To begin, locate the pressure relief valve on your heater. It is usually on the top or side of the tank.
- Place a bucket under the discharge pipe to catch any water.
- Lift the valve’s lever gently and let it snap back.
- Observe if water flows through the discharge pipe.
If water flows, the valve works correctly. If not, the valve may be faulty.
Replacing A Leaky Valve
A leaky valve can waste water and indicate a problem. Follow these steps to replace it:
- Turn off the gas supply to the water heater.
- Shut off the cold water inlet valve.
- Drain a few gallons of water from the tank using a hose.
Use a wrench to unscrew the faulty valve. Install the new valve by screwing it in tightly. Turn the gas and water supply back on and check for leaks.
Proper pressure relief valve checks ensure your heater functions safely.
