Cozy Heating Systems 1018350 Flame Sensor for Gas Wall Heaters and Furnaces

The Cozy Heating Systems 1018350 Flame Sensor is a genuine OEM replacement part designed for Cozy gas wall heaters and furnaces. This critical safety component continuously monitors the burner flame to ensure safe and reliable heating operation.

Key Features:

• Detects flame presence by monitoring UV light produced by the heating appliance
• Prevents dangerous gas buildup by shutting off the gas valve if flame is lost
• Essential safety device required for proper furnace operation
• Genuine Cozy OEM part ensures proper fit and function
• Compatible with Cozy direct vent wall furnaces and heating systems

How It Works:

The flame sensor works by detecting the presence of a flame at the burners and proving safe combustion before the heating cycle continues. If the flame is extinguished unexpectedly, the sensor signals the control board to immediately shut off the gas valve, preventing hazardous gas accumulation. This detection technique enhances both safety and energy efficiency by ensuring the burner operates correctly only when a flame is present.

Common Symptoms of a Faulty Flame Sensor:

• Furnace ignites but shuts off after a few seconds
• Error codes indicating ignition proving failure
• Repeated cycling attempts followed by lockout
• Heater won't stay running consistently

Regular maintenance of the flame sensor, including periodic cleaning to remove carbon buildup, helps ensure reliable heating system performance. Cozy heating products are manufactured by Williams Comfort Products and are known for premium quality components built by expert American craftsmen.
