Robertshaw 10-227 Flame Sensor with 1/4" Quick-Connect Terminal

The Robertshaw 10-227 is a replacement flame sensor designed for gas-fired heating appliances including furnaces, boilers, and water heaters. This critical safety component detects the presence of flame during burner operation to ensure proper ignition and prevent potentially dangerous gas flow without combustion.

Key Features:

• 1/4" quick-connect terminal for fast, secure electrical connection
• Direct replacement flame sensor for compatible Robertshaw systems
• Monitors flame presence to prevent unsafe gas discharge
• Durable construction designed for high-temperature environments
• Essential safety component for gas appliance operation

Flame sensors work by detecting the electrical conductivity of a flame. When the sensor rod is heated by the burner flame, it conducts a small current that signals the control board that ignition has occurred successfully. If the sensor fails to detect flame, the system will shut down gas flow as a safety precaution. The quick-connect terminal design simplifies installation and replacement, reducing service time.
