Water Heater Gas Control Valve Failure Can Cause Hot Water Problems

When you’re dealing with a water heater gas control valve failure, the water heater can no longer control the gas flow. The result? Too much hot water or none at all.

Check Your Water Heater Gas Valve

Your water heater has a series of parts that all need to work together to make sure that you get hot water when you need it.

Inside your water heater tank, there's a temperature probe behind the gas valve that senses the temperature of the water in the tank and tells the gas valve if it should open or close.

The gas valve responds by turning on or shutting off the gas to the main burner, which will maintain the temperature set on your water heater's thermostat. So, when your gas valve isn't working as it should, the temperature of your water can’t be controlled causing your hot water problems.

How to check for water heater gas control valve failure

  • Check that the pilot light is lit. Near the bottom of your water heater there is a metal cover. Lift it up and out, then look through the glass window behind it. The small flame you see is your pilot light. If the pilot light is out, the issue may not be the gas valve.

  • If the pilot light is lit but the burner won’t come on, there may be a problem with the gas valve. The first step is to make sure it's on. The valve should be turned to “On” and not “Pilot” or “Off.”

  • Wait 24 hours for it to settle down. If it didn't change the temperature of the water or it went the wrong way (colder or hotter), then the gas control on the hot water heater may need to be replaced.
