Understanding The Reasons Why Water Heater Flame Stays On

Is your water heater flame staying on even when you’re not using hot water? This could be a sign of a malfunctioning system. Here’s what you need to know about why your water heater flame stays on and how to fix it.

Malfunctioning Thermostat

A thermostat that’s not working correctly is one potential reason why your water heater flame is staying on. This issue could be caused by a faulty thermostat or one that’s not calibrated correctly. You can test this by turning the temperature down and seeing if the flame turns off.

The Thermocouple Is Faulty

The thermocouple is a sensor that measures the temperature of the pilot light. If it’s not working correctly, your system could think the pilot light is out and keep the flame on. This issue is often easy to fix by replacing the thermocouple.

Sediment Build-Up In The Tank

Over time, sediment can build up in your water heater tank, making it harder for the heat to transfer. This can cause the system to keep the flame on longer than necessary. Flushing the tank periodically can reduce sediment buildup and alleviate this issue.

The Gas Valve Is Defective

If your gas valve is defective, it could be causing your water heater flame to stay on. This issue can lead to dangerous leaks, so it’s important to have a professional fix it as soon as possible.

The Gas Pressure Is Inadequate

If your gas pressure is too low, this could cause your water heater flame to stay on. Check your gas lines to make sure they’re not blocked or corroded, which can cause low pressure.

The Pilot Orifice Is Clogged

If the pilot orifice is clogged, this could cause your water heater flame to stay on. This issue can often be fixed by cleaning the pilot orifice and burner assembly.

Understanding these potential reasons why your water heater flame is staying on can help you identify the issue and find the right solution. If you’re unsure about how to fix it, it’s best to call in a professional to ensure the safety and efficiency of your system.

Troubleshooting Techniques To Fix Water Heater Flame Staying On

If you own a water heater, you know how beneficial it can be, especially during the cold winter months. However, if the flame in your water heater stays on, it can lead to several issues, such as a high electricity bill or an unsafe living environment.

  • You hear a hissing or popping sound coming from the water heater.
  • The pilot light is yellow or flickering.

If you identify any of these problems, there’s a good chance that your water heater flame is staying on.

Checking The Thermocouple

A faulty thermocouple can cause the water heater flame to stay on. Here’s how to check it:

  • Turn off the gas and power source.
  • Detach the thermocouple and clean it with a wire brush.
  • Reattach it and turn the power source back on.

If your thermocouple is still faulty, you may need to replace it.

Flushing The Water Heater Tank

A dirty water tank can cause several problems, including the water heater flame staying on. Flushing the water heater tank can help:

  • Turn off power and gas to the water heater.
  • Connect a hose to the drain valve and drain the tank.
  • Refill and flush the tank several times.

Flushing the tank helps clear any debris that may be causing the problem.

Cleaning The Pilot Orifice

A dirty pilot orifice can cause the water heater flame to stay on. Cleaning it will help:

  • Turn off the gas and power source.
  • Disconnect the pilot tube and clean it with a wire brush.
  • Reconnect the tube, and turn the gas and power source back on.

Cleaning the pilot orifice helps provide an uninterrupted flow of gas.

Replacing The Thermostat

A faulty thermostat may cause the water heater flame to stay on. Here’s how to replace it:

  • Turn off power and gas to the water heater.
  • Disconnect the wires from the old thermostat and remove it.
  • Install the new thermostat and reconnect the wires.
  • Turn the power and gas source back on.

Replacing the thermostat helps maintain the right water temperature.

Replacing The Gas Valve

A faulty gas valve can cause the water heater flame to stay on. Here’s how to replace it:

  • Turn off the power and gas source to the heater.
  • Disconnect the gas line and electrical wiring connected to the valve.
  • Remove the old valve and install the new one.
  • Reconnect the gas line and electrical wiring, and turn the power and gas back on.
