What does it mean when your water heater pilot light keeps going out?

The pilot light is a small flame that turns on the gas burner in your water heater. These pilots are found on chimney or atmospheric vent heaters, and are to remain lit all the time. If the pilot doesn't turn on, goes out immediately after lighting, or repeatedly turns off, it's most likely a result of a bad thermocouple.

No Hot Water?

If there’s no hot water coming out of your pipes, your water heater’s pilot light has likely gone out due to a faulty thermocouple. Luckily, this is a quick fix that will restore hot water to your home in no time.

What is a Thermocouple?

Your system’s thermocouple is an electric device that shuts off the gas supply to your water heater if the pilot light goes out. It serves as a safety device. However, it’s only safe when it’s operated properly.

A faulty thermocouple will repeatedly shut off your pilot light and burner, meaning your water heater won’t be able to do what it’s supposed to: heat your water!

A Quick Fix

Fortunately, replacing your water heater’s thermocouple is a great opportunity to tap into your DIY ability! With some simple tools and a little bit of time, you can fix your system’s thermocouple yourself. However, there’s no shame in asking a professional to do the job, whether it be through HomeX Remote Assist or in person.
