True 807408 2 Pole Defrost Sensor, 59" Cable, Replacement with 12 Month Warranty & USA Business

Restore dependable defrost temperature monitoring in compatible commercial refrigeration equipment with the Wholesale Sensors Replacement True 807408 2-Pole Defrost Sensor 59″. Engineered as a perfect OEM-style replacement, this temperature sensor is designed to meet or exceed original functional specifications while providing accurate evaporator temperature feedback for proper defrost operation in compatible True commercial refrigerators and freezers.

Replacement for True 807408 Defrost Sensor

True Manufacturing identifies 807408 as an NTC thermistor defrost sensor. True’s current OEM parts information describes the 807408 as a 2-meter NTC thermistor probe with a blue stripe and states that it replaces 960670. The manufacturer identifies the thermistor element as EPC B57025M2502A1.

Additional commercial parts catalogs cross-reference True 807408 with previous numbers 945052, 947997, 960670, and 807405. Other documented references include E807408 and 217253. These numbers can help identify the correct replacement when servicing older equipment, but the complete True model and serial number should always be checked before ordering.

There is an important specification difference between current True documentation and some distributor catalogs. Current True OEM information describes the 807408 as a 2-meter, or approximately 78.74-inch, NTC probe, while established distributor catalogs describe the 807408 as a 2-pole, 59-inch capillary defrost sensor. Because your Wholesale Sensors product is specifically sold as the 59-inch version, customers should compare the original sensor length, connector configuration, model, and serial number before purchase.

Designed for Commercial Refrigeration Defrost Control

The 807408 performs a different function from the primary cabinet temperature sensor. Its job is to monitor temperature conditions associated with the refrigeration system’s defrost process.

Parts Town identifies the 807408 as a defrost sensor that helps prevent excessive ice accumulation on the evaporator coils. Proper defrost operation helps keep the evaporator clear so air can move across the coil and the refrigeration system can maintain normal cooling performance.

True specifically identifies 807408 as the defrost sensor with a blue stripe, while True 807409 is separately identified as a thermostat probe. This distinction is important. Customers should not assume the defrost sensor and cabinet thermostat probe are interchangeable simply because both components measure temperature.

Broad True Refrigerator and Freezer Compatibility

The True 807408 is documented across numerous commercial refrigeration platforms. Verified applications include TUC-24-HC, TUC-24F-HC, TUC-24G-HC-LD, TUC-27, TUC-27-HC, TUC-27F, TUC-27F-HC, TUC-27G, TUC-48-HC, TUC-48F-HC, TUC-60F, TUC-67F, TUC-93, TUC-93HD, TWT-27, TWT-27F, TWT-27F-HC, TWT-60F, TWT-67F, TWT-93, and TWT-93HD.

Additional verified applications include TFP-48-18M, TFP-48-18M-D4, TFP-72-30M, TFP-72-30M-D-6, TSSU-72-30M-B-ST-HC, TSSU-72-40-B-DS-ST, T-23DT, T-23DT-1-G-1, T-23DT-G, T-24-GC, T-24-GC-S, T-36-GC, T-36-GC-S, T-50-GC, T-50-GC-S, and GDM-33SSL-56-HC.

True’s current parts catalog also confirms 807408 in specific newer equipment such as TUC-27F-D-2-HC, TUC-36-HC, TRCB-52-60-HC, and STR1FPT-2HS-2HS-HC.

True equipment can vary by production date, controller, refrigerant configuration, and serial number. Always verify the original part before ordering.

Helps Restore Proper Defrost Performance

A failed or inaccurate defrost sensor can interfere with proper defrost control. When the refrigeration controller receives incorrect temperature information, the evaporator may not complete the intended defrost process correctly.

Possible symptoms can include evaporator frost or ice buildup, reduced airflow, inconsistent cabinet temperatures, extended refrigeration operation, abnormal defrost cycles, or declining cooling performance. The 807408 is specifically designed to monitor defrost conditions and help prevent excessive ice buildup on the evaporator coil.

These symptoms do not automatically confirm sensor failure. Evaporator icing can also result from airflow restrictions, door gasket leaks, evaporator fan problems, controller faults, wiring damage, refrigerant system problems, clogged drains, or other defrost system failures.

For that reason, proper diagnosis is recommended before replacing the sensor.

Built for Demanding Commercial Equipment

Commercial refrigeration equipment operates continuously in environments where temperature changes, condensation, moisture, foodservice activity, and repeated refrigeration cycles can place stress on electrical components.

The Wholesale Sensors replacement is built for dependable sensing performance under these conditions. Each sensor is rigorously tested for temperature response, electrical performance, sensing consistency, continuity, and reliability before use.

The NTC thermistor design responds to temperature changes so the compatible control can evaluate evaporator conditions and manage defrost operation appropriately. True confirms the current 807408 configuration as an NTC thermistor specifically intended for defrost sensing.

Installation and Troubleshooting

Installation should follow the original sensor location and wiring route. Disconnect electrical power to the refrigeration equipment before beginning service. Locate the original defrost sensor, document its position and wire routing, disconnect it from the control circuit, and install the replacement in the same intended sensing location.

Correct sensor placement is important. A defrost sensor installed in the wrong location may detect a different temperature than intended and provide inaccurate information to the refrigeration controller.

Commercial True refrigerators and freezers do not use automotive OBD-II diagnostic trouble codes. If the equipment displays a controller alarm or error, consult the service documentation for the exact model and control system. If problems remain after sensor replacement, inspect the controller, wiring, evaporator fan, defrost system, airflow, refrigeration system, and related components.
