Raypak 006021F Sensor

The Raypak 006021F Roll-Out/Flue Sensor is a safety-critical 150°F fixed-temperature switch engineered for precise thermal monitoring in high-efficiency Raypak boiler parts and pool heaters. As an essential OEM HVAC replacement sensor, this component is designed to detect flame roll-out or excessive flue gas temperatures, immediately breaking the safety circuit to prevent damage to the heat exchanger or cabinet. This Raypak roll-out switch functions as a normally closed contact that opens at its 150-degree threshold, ensuring that gas valves are de-energized if combustion parameters drift. For technicians servicing professional-grade hydronic systems, using genuine Raypak 006021F sensors is mandatory to maintain the safety listing and operational integrity of the equipment. Its rugged construction allows for reliable performance in the demanding environments found within flue collector assemblies and burner trays. Whether you are performing a seasonal tune-up or troubleshooting a lockout code, this 150f flue sensor provides the exact calibration required for system protection.

• Precise 150°F Calibration: Ensures immediate system shutdown upon detecting unsafe flue gas or roll-out temperatures.
• OEM Compatibility: Designed specifically for Raypak heaters, providing a seamless fit and electrical integration.
• Safety Compliance: Built to meet strict industry standards for flame and heat monitoring in residential and commercial boilers.
• Snap-Action Reliability: Features a high-quality thermal disc for consistent opening and closing cycles without drift.

• Can I use a higher temperature sensor if my flue gas is hitting 150°F? No. This sensor is calibrated to the manufacturer’s safety spec; a higher rating could lead to heat exchanger damage or unsafe operating conditions.
• What causes this sensor to trip frequently? Common causes include blocked flue vents, soot buildup on the heat exchanger, or improper gas pressure leading to flame roll-out.
• How do I test the Raypak 006021F? Use a multimeter to check for continuity across the terminals. If the sensor is cool but shows an open circuit, the internal disc has likely permanentally tripped or failed.
