Heil 1172827 Furnace Flame Sensor

The Heil 1172827 is an OEM flame sensor designed for Heil, Quaker, and ICP (International Comfort Products) brand furnaces. This critical safety component monitors the burner flame during furnace operation to ensure safe and reliable heating.

Key Features:

• OEM replacement part ensures perfect fit and function
• Monitors flame presence and prevents dangerous gas leaks
• Metallic rod design with porcelain insulation
• Compatible with multiple ICP family brands
• Replaces alternate part number LH33WZ520

How It Works:

The flame sensor generates a small electrical current when positioned in the burner flame. This current signals the furnace control board that ignition has occurred and combustion is taking place. If the sensor fails to detect a flame within seconds of the gas valve opening, it automatically shuts down the furnace to prevent unburned gas from escaping into your home.

Cross-Brand Compatibility:

This sensor works across the ICP family of brands including Heil, Quaker, Tempstar, Arcoaire, Comfortmaker, Day & Night, KeepRite, and Lincoln furnace models. Always verify compatibility with your specific furnace model before ordering.

Maintenance Note:

Flame sensors should be inspected annually and cleaned of carbon buildup to maintain proper function. Regular maintenance extends sensor life and prevents nuisance furnace shutdowns.
