Resideo by HoneyWell Q354A1018 Flame Sensor Rod - 6-Inch

The Resideo by Honeywell Q354A1018 is a 6-inch flame sensor rod designed for reliable flame detection in residential and commercial heating systems. This flame rod works in conjunction with electronic ignition systems to verify the presence of a flame and ensure safe furnace operation.

Key Features:

• 6-inch length provides proper positioning in the burner assembly
• Compatible with Honeywell S87CDK and S89EF flame safeguard controls
• Durable construction for long-lasting performance in high-temperature environments
• Direct replacement for worn or damaged flame sensors
• Essential safety component that prevents gas flow without flame presence

Flame sensors are critical safety devices that detect the presence of flame through flame rectification. When the sensor fails to detect a flame, the control system shuts off gas flow to prevent dangerous gas buildup. Regular inspection and replacement of flame sensors helps maintain safe and efficient furnace operation.
