Resideo by HoneyWell Flame Sensor Rod

The Resideo by Honeywell Flame Sensor Rod (also called a furnace flame sensor or flame rectification rod) is a replacement part for gas-fired furnaces and heating appliances. It confirms that the burner flame is lit while the gas valve is open. If the sensor does not detect a flame, the control board shuts off the gas. This protects the system against unburned gas buildup.

Key Features:

• Uses flame rectification to detect the burner flame and send a signal to the ignition control
• Rod-style sensing element made for the high heat inside a furnace burner compartment
• Helps the furnace light and run reliably, which can reduce nuisance lockouts and short cycling caused by a dirty or worn sensor
• Made by Resideo, the company that makes Honeywell Home heating and comfort controls
• Works as a direct replacement for a worn, corroded, or carbon-fouled original sensor
• Simple to install in most furnaces. It usually takes one mounting screw and a single wire connection

A flame sensor that is dirty or worn out is a common reason a furnace lights and then shuts off after a few seconds. Replacing it restores a steady flame signal and dependable operation. Several versions are offered in this product line. Choose the one that matches your furnace's requirements.
