Why a Pilot Light Won’t Stay Lit?
Pilot lights are an essential component of many appliances, such as water heaters, furnaces, and gas ranges. They provide a steady flame that ignites the main burner, allowing the appliance to function properly. However, sometimes the pilot light can fail to stay lit, causing frustration and discomfort. In this article, we will explore the common reasons why a pilot light won’t stay lit and provide solutions to get it running again.
What Causes a Pilot Light to Not Stay Lit?
There are several reasons why a pilot light may not stay lit. Here are some of the most common causes:
- Poor Quality Pilot Light Assembly: If the pilot light assembly is of poor quality or installed incorrectly, it may not be able to maintain a stable flame.
- Incorrect Pilot Light Adjustment: If the pilot light is not adjusted correctly, it may not be able to sustain a flame.
- Dirty or Clogged Pilot Light: A dirty or clogged pilot light can prevent the flame from burning properly, causing it to go out.
- Faulty Thermocouple: The thermocouple is responsible for sensing the pilot light flame and regulating the gas flow. If it’s faulty, it may not be able to maintain a flame.
- Gas Leak: A gas leak can cause the pilot light to malfunction and not stay lit.
- Pilot Light Damaged: If the pilot light is damaged or cracked, it may not be able to maintain a flame.
