A Bad Thermocouple Might Be The Cause Of Your Hot Water Heater Failure

There are few things worse in life than having to take an ice-cold shower in the morning because you have no hot water. If your hot water heater operates on gas, you may want to try a simple fix before calling a repair company to come to your home. The simple fix is relighting the pilot light if it is out. If it will not stay lit, the problem could be due to a faulty thermocouple on the device.

What is a thermocouple?

All gas hot water heaters have a small part known as a thermocouple. Thermocouples are also found on many types of furnaces and other devices that require the use of gas. A thermocouple is an inexpensive part of a hot water, but it serves a giant purpose.

Its purpose is to stop gas from going into the system when the pilot light on the device is not on. In other words, a thermocouple is a safety device on your hot water heater. If your pilot light goes out for any reason, it will prevent the system from producing hot water. If the thermocouple was not there, gas would continue flowing, and this could create a major risk in your house, because gas is explosive.

What happens when a thermocouple wears out?

When a thermocouple is working properly, it causes the gas to release into the water heater so it can produce hot water. When a thermocouple wears out, it stops all gas from entering the system. In addition, a bad thermocouple will typically cause the pilot light on the system to go out.

If the pilot light is off and you cannot get it to stay lit, it could be a good indication that the thermocouple is bad. Another reason pilot lights will not stay lit is from dirt buildup in the burner. If the burner gets too dirty, the pilot light will not be able to stay on.

Can you fix this yourself?

While some people might attempt to replace a thermocouple themselves, it is not recommended unless you have experience working with gas devices. If you fail to shut the gas off before making this repair, you might end up with major problems on your hands. It is safer and easier to hire a repair company to fix this problem for you.

Living without hot water is not pleasant for many reasons, but there are companies that can help. If you cannot fix the problem yourself, you can call a water heater repair company.
