Carrier Hot Surface Ignitor Furnace Ignitors & Flame Sensors

Carrier hot surface ignitors (also called furnace igniters or HSI) are replacement components for gas furnace ignition systems. When the thermostat calls for heat, the ignitor heats up to a temperature high enough to light the gas burners. This gives dependable, standing-pilot-free operation and helps your heating system start reliably.

Key Features:

• Designed for use in Carrier gas furnace ignition systems
• Hot surface design replaces a constantly burning pilot light, which improves efficiency
• Heats quickly to ignition temperature for consistent burner lighting
• Built to meet Carrier specifications for fit and performance
• Suited to routine maintenance and replacement of worn or cracked ignitors

A weak, cracked, or failed ignitor is a common cause of a furnace that won't start or that cycles without lighting. Replacing it with a Carrier ignitor restores dependable heating. Select the child item that matches your furnace's part number or model requirements.
