Utica-Dunkirk 240007909 Sensor
The Utica-Dunkirk 240007909 Sensor is a critical OEM replacement component engineered for precision temperature monitoring within hydronic heating systems and industrial boiler applications. This 60-inch thermistor sensor serves as a high-limit or operating control, providing accurate resistance feedback to the control board to regulate thermal cycles and prevent overheating conditions. Designed for seamless integration with ECR International brands, including Utica Boilers and Dunkirk Boilers, this NTC temperature sensor ensures the system maintains peak operational efficiency while protecting the heat exchanger from thermal stress.
For field technicians, the 240007909 HVAC sensor features a robust 60" lead length, allowing for versatile routing through tight boiler jackets and wiring harnesses. Its durable construction is built to withstand the high-ambient environments common in commercial gas-fired boilers and residential forced hot water systems. When troubleshooting "no-heat" calls or sensor short errors, utilizing a genuine Utica-Dunkirk replacement part is essential for maintaining factory safety certifications and ensuring consistent communication with the primary ignition module or control interface.
Key Benefits- Precise Thermal Feedback: High-accuracy NTC thermistor technology ensures the control module receives real-time data for optimized firing rates.
- Extended 60-Inch Reach: The generous lead length simplifies installation in large-scale boiler cabinets without the need for wire extensions.
- Direct OEM Compatibility: Engineered specifically for ECR International heating equipment to ensure a drop-in fit and reliable electrical termination.
- System Protection: Critical for monitoring high-limit thresholds, preventing boiler scaling and premature component failure due to excess heat.
What are the signs of a failing sensor?
Technicians typically encounter lockout codes on the control board or erratic temperature readings. A faulty sensor may show infinite or zero resistance when tested with a multimeter, usually indicating an internal short or open circuit from thermal fatigue.
Can I use this for both supply and return lines?
Yes, if the system specifications call for a 60-inch sensor with this specific resistance profile, it is commonly used for monitoring both supply and return water temperatures in modulating condensing boilers.
Are special tools required for installation?
No special tools are required beyond standard HVAC hand tools, though we recommend a digital multimeter to verify the ohm readings against the manufacturer's resistance chart during commissioning.
