3 Helpful Tips For Troubleshooting Your Gas Water Heater

Posted on: 27 February 2017

Not many people would argue that the gas water heater is an inconsequential appliance; in fact, most would probably list it among the most important in the average home. Not having a water heater that is working properly can be enormously frustrating, but that doesn't mean that you're helpless. Take a look below at a handful of troubleshooting tips that will come in handy when you notice something that's not quite right with your gas water heater.


If your pilot won't light, there are a few possible culprits. One of the most common is the thermocouple. This is basically a safety device that allows gas through the valve when it senses that the pilot is lit. A faulty thermocouple means that the gas valve won't let any gas through. Fortunately, this is a fairly routine fix that won't cost you more than a few dollars in parts. Another possible (though less common) reason that your pilot won't light is that the gas valve itself is clogged or somehow malfunctioning. This is a more complicated fix but still fairly routine. If you are doing any repairs yourself, be sure to shut off the gas before you begin working!


Sometimes, the first clue that something is wrong with your gas water heater is the temperature of your water is off. For most people, this is a rude awakening in the form of a freezing cold shower, though of course the opposite can also happen, and you can find yourself on the receiving end of scalding water. More often than not, this is a sign that the thermostat on your water heater isn't working properly. In other words, it is measuring the temperature of the water to be something other than what it actually is and as a result is delivering water that is too hot or cold (or sometimes simply lukewarm). Get your thermostat replaced, and you can go back to enjoying normally heated water immediately. 


If you notice that your gas water heater is operating far less efficiently than it used to, then you can usually blame a clogged vent. There are two main types of vents: direct and power, the latter of which is most common because it doesn't require exhaust gases to be piped through a vertical space. Regardless, replacing or unclogging a vent can have your water heater operating like new in no time.
