Water Heater Burner Wont Stay Lit

Have you ever experienced when your water heater burner won’t stay lit? Well, this is actually a common condition that is often happened on the gas water heater. Some factors may lead to this matter. But generally, it is due to the defective control thermostat.

What is a control thermostat actually? It is a part of the gas valve assembly with a sort of dial to adjust the temperature. Besides, another part is the probe that is functioned to monitor the temperature of the water. Based on this fact, it can be seen that this valve controls the supply of gas.

If it is already detected that the control is defective, it can be both repaired and replaced. However, repairing tends to be more difficult. Besides, the damage that occurred is also commonly permanent.

The most common action to do when you see that the heater won’t stay lit is by asking the electronic service to help you. However, fixing this problem can actually be done by you. It is by opening all the panels and then replace the control thermostat. The products are offered in the electronic component shops all around.

Sure, the defective control thermostat is not the only problem due to the water heater’s inability to stay lit. Another problem is due to another component, namely the thermocouple. The indicator of whether the thermocouple functions well or not is due to the small voltage generated by this component to keep the gas flowing.

On the other hand, when there is something wrong regarding the thermocouple, the proper voltage signal will not be received. The thermocouple itself can be found in the pilot flame, and this is what makes the pilot flame burnt out.

So, what should we do if the thermocouple becomes the main problem? Why your gas water heater cannot function well in general? Like the problem that occurred with the thermostat, it is more recommended for you to replace this component even if repairing is possible.

The reason is that replacement is much easier and faster than repairing. The most difficult part in the replacement is probably placed when you need to release all the outer coverage.

You may also need some tools like the screwdriver since there will be many screws to be released. The experienced ones are recommended to fix this problem by themselves but not if you are not experienced enough.
