Heatcraft Refrigeration 28900107 Temp Sensor
The Heatcraft Refrigeration 28900107 is a critical NTC thermistor temperature sensor engineered specifically for integration with Beacon II and Beacon III electronic controller systems. This 10k ohm @ 25?C refrigeration sensor provides the high-accuracy resistance feedback required for precise evaporator coil temperature monitoring, room ambient air sensing, and defrost termination control. Designed to withstand the rigorous thermal cycling of commercial refrigeration environments, the 28900107 ensures the controller maintains stable superheat levels and optimal compressor cycling. Whether being used in walk-in coolers or industrial freezers, this OEM component delivers the linear voltage response necessary for the Beacon II control board to prevent ice accumulation and over-cooling. For field technicians, verifying the B-value and resistance-temperature curve is essential for maintaining system efficiency and protecting high-value inventory from temperature drift. This sensor is a direct-fit replacement for standard Heatcraft, Bohn, and Chandler evaporator units utilizing digital controls.
Key Benefits- OEM Precision: Guaranteed compatibility with Heatcraft Beacon II control logic for accurate thermal reporting.
- Moisture Resistance: Encapsulated thermistor bead prevents moisture ingress in high-humidity evaporator environments.
- Quick Response: High-sensitivity thermal conductivity leads to faster defrost cycles and reduced energy consumption.
- Direct Integration: Simplified 2-wire lead connection for rapid field replacement on Bohn evaporator coils.
Can this sensor be used with non-Beacon controllers?
The 28900107 is calibrated specifically for the Heatcraft Beacon platform. Using it with third-party controllers may result in incorrect temperature readings due to differing resistance curves.
How do I test if the thermistor is faulty?
Using a multimeter set to the 20k ohm scale, measure the resistance of the temperature sensor. At 77?F (25?C), the reading should be approximately 10,000 ohms. A reading of infinity or zero indicates a failed component.
Where should this sensor be mounted on the coil?
For defrost termination sensing, the 28900107 should be mounted on the liquid line or the coldest part of the coil, strictly following the Heatcraft refrigeration wiring diagram for your specific model.
