Carrier Flame Sensor for Gas Furnaces

The Carrier flame sensor (also called a flame rod or flame probe) is a replacement furnace part for gas-fired heating systems. It is a safety component. It confirms that the burner has lit and that a flame is present during the heating cycle.

How It Works:

• The sensor rod sits in the burner flame. It produces a small flame-rectification current that the furnace control board monitors.
• If the flame goes out or is not detected, the control board shuts off the gas valve. This helps prevent unburned gas from building up.
• A dependable signal helps the furnace run through complete heating cycles. It reduces nuisance lockouts and short cycling.

Key Features:

• Made for Carrier gas furnaces as a replacement for the original sensor
• Corrosion-resistant metal rod that withstands repeated high-heat cycles
• Insulated mounting base and terminal for a secure, stable connection
• Simple to install and replace with basic hand tools

Benefits: Flame sensors can build up carbon and oxidation over time. This can cause intermittent shutdowns, flame-detection faults, or a furnace that lights and then goes out. Replacing a worn sensor with a Carrier part restores consistent flame detection. It also helps keep the furnace operating safely and efficiently.
