ARAGSD100140 - Genuine OEM Danby Defrost Sensor

ARAGSD100140 – Genuine OEM Danby Defrost Sensor

The ARAGSD100140 Genuine OEM Danby Defrost Sensor is an original manufacturer temperature-sensing component designed for Danby refrigeration and freezer systems, including select wine coolers and compact refrigeration units. This OEM defrost sensor plays a critical role in monitoring evaporator temperature and ensuring proper defrost cycles. Available from Appliance Kingdom, this part ships across Canada with fast delivery, making it a reliable choice for homeowners, landlords, and appliance repair technicians seeking accurate, factory-spec replacements.

This component is commonly used to resolve issues related to frost buildup, inconsistent cooling, and improper defrost operation when the original sensor fails or drifts out of calibration.

Function & Importance of the Defrost Sensor

The defrost sensor (also known as a thermistor) continuously measures the temperature of the evaporator coil inside the appliance. It sends real-time data to the control board, which uses this information to decide when to initiate and stop defrost cycles.

In Danby refrigeration systems, precise sensor readings are essential. If the sensor provides incorrect resistance values or fails completely, the system may either over-freeze or fail to defrost, leading to ice buildup and restricted airflow.

Using a genuine OEM sensor ensures:

• Accurate temperature readings for proper defrost timing
• Correct communication with the electronic control board
• Stable cooling performance and energy efficiency
• Long-term reliability under repeated thermal cycling

Common Symptoms of a Faulty Defrost Sensor

When the ARAGSD100140 defrost sensor begins to fail, you may notice:

• Excessive frost or ice buildup on evaporator coils
• Refrigerator or freezer not cooling properly
• Inconsistent or fluctuating internal temperatures
• Compressor running continuously without proper cycling
• Defrost cycle not activating or ending too early
• Water leakage inside the unit due to ice melt overflow
• Warm refrigerator compartment despite freezer running

If these symptoms are present, replacing the defrost sensor often restores proper system balance—provided other components like the defrost heater and control board are functioning correctly.
