What is a Gas Water Heater Pilot Light?

The gas water heater pilot light is a small, continuously burning flame that ignites the gas in your water heater. Its primary function is to ensure that the burner ignites when hot water is needed. The pilot light is typically located near the burner assembly and is essential for the water heater's operation.

How Does the Gas Water Heater Pilot Light Work?

The pilot light operates using a steady supply of gas, which it ignites to create a flame. When the water temperature drops below a certain level, the thermostat signals the gas valve to open, allowing gas to flow to the burner. The pilot light then ignites the gas, heating the water. This process continues until the desired water temperature is reached, at which point the thermostat shuts off the gas supply.

Why is My Gas Water Heater Pilot Light Out?

There are several reasons why your gas water heater pilot light might go out. Common causes include:

• Drafts or wind blowing out the flame
• Faulty thermocouple that doesn't detect the flame
• Gas supply issues or interruptions
• Accumulation of dust or debris around the pilot light area
