Utica-Dunkirk 240008290 Sensor
The Utica-Dunkirk 240008290 Water Sensor is a critical 12K NTC thermistor designed for precise hydronic temperature monitoring in high-efficiency ECR International boiler systems. Real-world service demands accurate data feedback to the control board to manage modulation and prevent short-cycling. This 1/4" NPT water sensor provides a high-sensitivity resistance curve (12,000 Ohms at 25°C), ensuring the boiler’s logic can maintain tight setpoint control for maximum fuel efficiency. As an OEM ECR International replacement part, it is the standard high limit sensor or supply/return probe for professional residential and commercial series.
Engineered for long-term immersion in harsh boiler environments, the brass-housed sensor resists scaling and corrosion that often degrades universal aftermarket alternatives. This negative temperature coefficient sensor features a standard threaded connection for a leak-free seal and is fully compatible with Utica SSC and Dunkirk VLT condensing gas boilers. Replacing a drifting or failed NTC temperature probe with a genuine 240008290 ensures the safety circuit remains calibrated and system response stays within factory specifications.
Key Benefits- OEM Precision: Guaranteed 12K Ohm resistance curve for exact temperature-to-voltage conversion.
- System Compatibility: Direct fit for Utica Dunkirk condensing boilers, including SSC and VLT models.
- Rugged Construction: 1/4" NPT threads and durable sensor tip built for immersion-style sensing.
- Enhanced Efficiency: Accurate thermal feedback prevents erratic burner behavior and energy waste.
Is the 240008290 interchangeable with a 10K NTC sensor?
No. This is a 12K NTC thermistor. Using a 10K sensor will result in incorrect temperature readings and potentially dangerous high-limit conditions. Always match the Ohm rating to the control board requirements.
Will this sensor fix a "High Limit" or "Short" error code?
Yes, if the error is caused by a failed or drifting probe. Modern modulating condensing boilers rely on these sensors to detect overheating; a 240008290 replacement restores accurate safety reporting.
Does this part require a specialized sealant for the 1/4" NPT threads?
Standard HVAC high-temperature pipe dope or PTFE tape is recommended for the NPT connection to maintain a pressure-tight seal without interfering with the sensing element.
