Product Details

The Supco FLS013 is a replacement hot surface ignitor (HSI) flame sensor designed for gas furnaces and heating systems. This critical component monitors the presence of a flame to ensure safe and reliable furnace operation.

Key Features:

  • Direct replacement for LH33WZ514, LH33WZ516, and LH680013
  • Hot surface ignitor technology for reliable flame detection
  • Compatible with various gas furnace models
  • Ensures safe furnace operation by confirming flame presence
  • Quality construction for long-lasting performance

The flame sensor works by detecting the electrical conductivity of the flame, ensuring that gas only flows when ignition has occurred. If the sensor fails to detect a flame, the furnace will shut down to prevent unsafe gas buildup. This Supco replacement part restores proper flame sensing functionality to keep your heating system running safely and efficiently.
