Reznor 123195 Cadmium Sulfide Flame Detector

The Reznor 123195 is a cadmium sulfide (cad cell) flame detector designed for oil-fired heating equipment. This safety component monitors flame presence during burner operation, providing critical flame supervision to ensure safe and reliable heating system performance.

Key Features:

• Cadmium sulfide photocell sensor for accurate flame detection
• Designed specifically for Reznor oil-fired heaters and furnaces
• Quick response time to flame presence and absence
• Direct OEM replacement part ensuring proper fit and function
• Essential safety component that helps prevent dangerous ignition failures

The cad cell flame detector works by sensing light from the oil burner flame. When the flame is present, the photocell's resistance drops, signaling the control system that combustion is occurring. If the flame is not detected during the ignition cycle or is lost during operation, the safety control will shut down the burner to prevent fuel spillage and hazardous conditions. Regular replacement of the cad cell detector is recommended as part of routine maintenance to ensure continued safe operation of your Reznor heating equipment.
