When Your Water Heater’s Pilot Light Becomes Your Home’s Biggest Headache
Nothing ruins a peaceful morning like stepping into what should be a hot shower only to be greeted by an icy blast of cold water. If you’re dealing with a water heater pilot light that keeps going out, you’re not alone—this frustrating problem affects thousands of homeowners across New Jersey and beyond. Understanding why this happens and knowing how to address it can save you from repeated cold showers and potentially costly emergency repairs.
Understanding Your Water Heater’s Pilot Light System
The pilot light on your water heater is the little blue flame used to light the gas streaming to your heater from the gas pipes coming from outside your home. While some people believe that a water heater turns on when the pilot light ignites, traditional pilot lights are lit 24/7. The whooshing sound you hear when the heater kicks on is actually the unit’s valve releasing gas into the burner, where it’s then ignited by the awaiting flame.
This small but crucial component serves as the ignition source for your water heater’s main burner. This initial source of ignition is what the pilot light is there for. It’s a constantly running flame that’s there to ignite the gas. When functioning properly, it should burn as a steady blue flame, ready to light the main burner whenever hot water is needed.
How to Identify Pilot Light Problems
Before diving into troubleshooting, it’s important to recognize the signs of pilot light issues. Other than visually checking your hot water pilot light, other signs can point to a problem. You might not have hot water or hear your heater running.
Visual inspection is straightforward: You should be able to see a little flame if your pilot light is lit. If you don’t see an obvious flame, your pilot light is out and you must relight it. Additionally, your pilot light should burn blue if it’s working correctly. If it’s burning yellow or red, this means it isn’t burning hot enough. Your pilot light should be a steadily burning stream. If it’s flickering or waving around, this means something is wrong.
Common Causes of Pilot Light Failures
Thermocouple Malfunctions
The most frequent culprit behind pilot light problems is a faulty thermocouple. Your thermocouple is a device that senses when your pilot light is burning. The tip of the thermocouple sits over the pilot flame, generating a voltage that keeps the gas valve open. Over time, thermocouples can malfunction, accumulate dust buildup, or get bent away from the pilot light’s flame. Either way, the thermocouple will struggle to sense the pilot light and stop the gas supply.
Airflow and Ventilation Issues
Another reason your gas water heater pilot light won’t stay lit is that it is not getting enough combustible air. Your water heater requires fresh air with oxygen to keep the pilot light burning. Otherwise, the flame goes out. Conversely, the air around a pilot light impacts how it functions. Air moving around the flame can disrupt it or blow it out entirely.
When investigating a water heater pilot light that won’t stay lit, be on the lookout for drafts that could blow out the pilot light. Sometimes, an open door (if your water heater is in the garage or a utility room that opens to the outside) could be enough to allow a gust of wild to extinguish that small, somewhat fragile flame.
Condensation Problems
Condensation is a normal part of modern energy-efficient water heaters. Even though water heaters produce condensation, too much of it can actually drip into your pilot light’s tube. Of course, water and fire don’t mix, so the condensation will essentially water down your pilot light.
Dirty or Clogged Components
A dirty pilot light opening (called an “orifice by HVAC contractors) will cause the pilot flame to become a wavy yellow flame. This flame isn’t hot enough and can’t properly heat the thermocouple. Additionally, the tube that brings gas to your pilot light can become clogged, shutting off the gas flow to the pilot light.
When to Call Professional Help
While some basic troubleshooting can be done safely by homeowners, fixing your pilot light is possible on your own but can be incredibly difficult. Simply diagnosing why your water heater pilot light keeps going out is a job of its own. However, finding a way to fix it after you’ve diagnosed the issue is another thing altogether. That’s why it’s best to leave issues like this to the professionals.
