Whirlpool Defrost Sensor: A Guide to Understanding and Troubleshooting

Introduction

If you own a Whirlpool refrigerator, you may have heard of the defrost sensor. This small but important component plays a crucial role in keeping your fridge running smoothly. In this article, we will discuss what a defrost sensor is, how it works, and what to do if it malfunctions.

What is a Defrost Sensor?

A defrost sensor is a temperature sensor that is located in the freezer compartment of your Whirlpool refrigerator. Its main function is to monitor the temperature of the evaporator coil and signal the defrost system to turn on when the coil becomes too cold. This prevents ice buildup on the coil, which can lead to reduced cooling efficiency and even a complete breakdown of the fridge.

How Does a Defrost Sensor Work?

The defrost sensor works by measuring the temperature of the evaporator coil. When the coil temperature drops below a certain threshold, the sensor sends a signal to the defrost system to turn on. The defrost system then heats up the coil, melting any ice that has accumulated on it. Once the ice has melted, the defrost system turns off and the fridge returns to its normal cooling cycle.

What are the Signs of a Malfunctioning Defrost Sensor?

If your Whirlpool refrigerator is not cooling properly, it could be a sign of a malfunctioning defrost sensor. Other signs of a faulty sensor include:

– Ice buildup on the evaporator coil
– Frost buildup on the freezer walls
– Water leaking from the freezer
– Unusual noises coming from the fridge

If you notice any of these symptoms, it is important to have your fridge inspected by a professional technician.

Conclusion

The defrost sensor is a critical component of your Whirlpool refrigerator’s defrost system. It helps prevent ice buildup on the evaporator coil, which can lead to reduced cooling efficiency and even a complete breakdown of the fridge. If you suspect that your defrost sensor is malfunctioning, it is important to have it inspected by a professional technician. By understanding how the defrost sensor works and what to look for when it malfunctions, you can help keep your fridge running smoothly for years to come.
