International Comfort Products 1172827 Flame Sensor for Gas Furnaces HVAC Sensors & Probes

The International Comfort Products 1172827 is a genuine OEM flame sensor designed for residential gas furnaces and heating systems. This critical safety component detects the presence of flame in the burner assembly and sends a signal to the control board to confirm safe ignition and continued operation.

How It Works:

The flame sensor monitors the burner flame during operation. When flame is detected, it sends a signal to the furnace control board, allowing the gas valve to remain open. If no flame is detected, the sensor prevents the system from igniting, protecting against dangerous gas leaks and unsafe operating conditions.

Key Features:

• Genuine OEM part ensuring exact fit and reliable performance
• Angle bend design for proper positioning in the flame path
• Durable construction for long-term reliability in high-temperature environments
• Direct replacement for worn or corroded flame sensors
• Includes mounting bracket for secure installation

Compatible Brands:

This flame sensor is used in select models from multiple brands including AcroAire, Bryant, Carrier, Comfortmaker, Heil, ICP, Keeprite, Kenmore, Sears, Snyder General, Tempstar, and Day & Night furnaces.

Replaces: Carrier LH33WZ550, LH33WZ520, LF18-194

Common symptoms of a failing flame sensor include the furnace starting but shutting down after a few seconds, frequent cycling, or the burner failing to stay lit. Regular maintenance and replacement of corroded or carbon-fouled flame sensors helps ensure safe and efficient furnace operation.
