Common Reasons Your Water Heater Isn’t Working

Pilot Light and/or Thermocouple 

Most people are familiar with a pilot light, but some people might not be aware of what a thermocouple is. A thermocouple is a sensor that sits close to the pilot light and detects if there is enough heat coming from the pilot light. If there isn’t enough heat (as is the case when the pilot light goes out), the thermocouple shuts off the gas flowing into the water heater. This way, it keeps gas from continuing to flow when there isn’t any flame to consume it. If the pilot light goes out, then you’ll need to relight it. If you see that the pilot is lit, but the water heater isn’t actually heating anything, it could be that the thermocouple is broken and has shut off the flow of gas.


Your water heater has a thermostat to tell it when it needs to heat more hot water. If you’re not getting enough hot water, it could be that the thermostat is malfunctioning. If this is the case, you’ll likely need to call for the services of a professional contractor to replace the thermostat assembly.


Over time, sediment and minerals can build up on the bottom of your water tank. This can create a barrier to the heat that needs to get into the water. If your water heater is old, this could be the case. You’ll need to call a professional contractor to know for sure. Many times a banging or rumbling noise will accompany this problem.
