Fully compatible with Luxaire and York gas furnace models listed. Key Benefits and Features: Ensures safe and efficient furnace operation by detecting and monitoring the burner flame throughout the heating cycle. Automatically shuts off the gas supply if the flame is unexpectedly lost, preventing gas leaks and enhancing safety. Precision manufactured from durable metal and ceramics for longlasting performance and resistance to heat wear. Welltested by the manufacturer to meet standards. Simple installation process – remove the worn or faulty sensor and with the unit. Function: The flame sensor plays a critical role in the furnace's ignition system. It confirms successful ignition and continues to monitor the flame while the unit is running. If combustion stops for any reason, the sensor detects the loss of flame and signals the gas valve to close, safeguarding your home and heating system. Use Scenarios: 1. Replacing a nonfunctioning flame sensor when your furnace ignites but quickly shuts down, ensuring continued heat supply. 2. Preventing safety hazards when the furnace fails to detect a flame due to a damaged or worn sensor. 3. Restoring proper operation after routine maintenance or troubleshooting issues caused by intermittent ignition. Compatibility: This sensor directly replaces the listed part numbers and works with specific Luxaire and York gas furnace units. Confirm your furnace model and part number before for fit. Materials and Build: Constructed from quality, wearresistant metal and ceramic components, this sensor is engineered to withstand temperatures and repeated use. Performance: Reliable detection and accurate shutoff capabilities help maintain efficiency, safety, and consistent heating performance. Installation: Requires minimal tools. Remove your existing flame sensor, position and secure the sensor, and reconnect according to manufacturer guidelines. By replacing a faulty flame sensor with this qualitytested unit, you help ensure that your furnace operates safely, efficiently, and consistently during the heating season.
