Utica-Dunkirk FE3980G050 Sensor
The Utica-Dunkirk FE3980G050 Temperature Sensor is a precision-engineered OEM replacement part designed for critical monitoring within the heat exchanger and fluid cycles of high-efficiency boilers. As a veteran-grade NTC thermistor, this sensor provides the control board with real-time resistance data to manage modulation and prevent high-limit lockout conditions. This specific FE3980G050 sensor is a direct-fit component for a range of ECR International brands, ensuring the system maintains its original ASHRAE-rated efficiencies and safety certifications. In the field, accurate boiler temperature sensing is the difference between a smooth-running hydronic loop and a nuisance "b 9" or "soft lockout" error. This fe temp sensor is built to withstand the thermal cycling typical of commercial and residential hydronic environments, providing reliable feedback for both supply and return monitoring. When diagnosing irregular burner cycling or fluctuating gauge readings, replacing an aging sensor with this genuine factory component ensures the aquastat and control module receive the precise signals required for optimal fuel-to-air ratios and safe condensate management.
Key Benefits- Precise Modulation Support: Delivers accurate resistance-to-temperature data, allowing the control board to modulate the burner for maximum fuel efficiency.
- Universal Compatibility: Engineering-matched for Utica and Dunkirk models including CCB-150, CHB-100, CHB-130, and CHB-150 series.
- System Protection: Acts as a primary feedback loop to prevent overheating and dry-fire conditions by monitoring heat exchanger exit temperatures.
- OEM Integrity: Maintains factory system ratings and prevents the electrical noise or drift often associated with generic aftermarket thermistors.
- How do I verify if the FE3980G050 is faulty? Use a multimeter to check the resistance against the manufacturer’s R-T chart (Resistance vs. Temperature); an open circuit or radical drift from the baseline suggests immediate replacement is needed.
- Can this sensor be used for both supply and return lines? Yes, in many CCB and CHB configurations, the same FE series sensor is utilized for both ports to ensure consistent data across the heat exchanger.
- Will this fix a "no flame ignition" error? While ignition issues can be complex, a faulty temperature sensor telling the board the unit is already at the high limit will prevent the ignition sequence from starting.
