The Hidden Danger of Overheating: Why Pilot Lights Go Out in Hot Attics and How to Fix It

Imagine this: It’s the middle of a scorching summer, and you’re in the comfort of your cool home, unaware that your attic is a sweltering hotbox. You head out for the day, but when you return, you notice something strange—your gas-powered furnace or water heater isn’t working. After some investigation, you discover that the pilot light has gone out. This can be frustrating, especially when you rely on these systems for comfort and essential services. But did you know that an overheated attic could be the culprit?

An Overheated Attic: A Common Yet Overlooked Problem

One of our customers, let's call him Mike, r



ecently experienced this very issue. Mike had been having trouble with his water heater’s pilot light going out repeatedly. At first, he chalked it up to faulty equipment or a draft in his home. But after multiple attempts to relight the pilot, he realized something more was going on.

When we got the call, we started by asking a few questions about Mike’s attic. It turns out that Mike’s attic was extremely hot—reaching well over 120 degrees on particularly warm days. This kind of heat is not uncommon in attics, especially those with inadequate ventilation. Unfortunately, this excessive heat can wreak havoc on your home’s systems.

Why Does Heat Cause Pilot Lights to Go Out?

Pilot lights are sensitive to their environment. When the temperature in an attic climbs too high, it can cause the thermocouple—a safety device that detects whether the pilot light is on or off—to malfunction. The intense heat can cause the thermocouple to believe the pilot light has gone out, even if it’s still lit, prompting it to shut off the gas supply as a safety measure.

Additionally, high attic temperatures can create unstable air pressure, leading to drafts that can extinguish the pilot light. These problems are particularly common in homes where the attic is poorly ventilated.

The Solution: Proper Ventilation with an Attic Fan

When we arrived at Mike’s home, it was clear that his attic needed better ventilation. We conducted a thorough inspection and found that the lack of airflow was not only causing the attic to overheat but also creating a breeding ground for potential issues like mold and higher energy bills.

To remedy the situation, we recommended installing a properly placed attic fan. Attic fans work by drawing hot air out of the attic and replacing it with cooler outside air. This simple solution dramatically reduces the temperature in the attic, helping to protect the pilot light from overheating and ensuring the safety and efficiency of your home’s systems.

Benefits of an Attic Fan

Installing an attic fan offers several advantages:

  1. Consistent Temperatures: By regulating attic temperatures, an attic fan reduces the risk of pilot light outages and improves the overall efficiency of your home’s heating and cooling systems.

  2. Energy Savings: Cooler attic temperatures can ease the burden on your air conditioning system, leading to lower energy bills.

  3. Increased Lifespan of Home Systems: Proper ventilation prevents overheating, which can extend the lifespan of your furnace, water heater, and other systems reliant on a stable environment.

  4. Improved Home Comfort: With a cooler attic, your home will be more comfortable year-round, especially during the hot summer months.
