Defrost Sensor Location: A Guide to Finding It

Defrost sensors are an essential component of refrigerators and freezers. They help regulate the temperature and prevent frost buildup, ensuring that your food stays fresh and safe to eat. However, if your defrost sensor malfunctions, it can cause serious problems with your appliance. In this article, we will discuss the defrost sensor location and how to find it.

What is a Defrost Sensor?

A defrost sensor is a small device that monitors the temperature of the evaporator coil in your refrigerator or freezer. When the temperature drops below a certain point, the sensor sends a signal to the control board, which activates the defrost cycle. This cycle melts any frost or ice buildup on the coil, preventing it from blocking the airflow and causing cooling problems.

Where is the Defrost Sensor Located?

The defrost sensor is usually located on the evaporator coil itself, which is located inside the freezer compartment. To find it, you will need to remove the back panel of your freezer. This panel is usually held in place by screws or clips, which you can remove with a screwdriver or pliers.

Once you have removed the panel, you should be able to see the evaporator coil. The defrost sensor is usually attached to one of the fins on the coil, either with a clip or adhesive. It is a small, rectangular device with two wires attached to it.

How to Test the Defrost Sensor

If you suspect that your defrost sensor is malfunctioning, you can test it with a multimeter. First, unplug your refrigerator or freezer and remove the back panel to access the sensor. Then, disconnect the wires from the sensor and set your multimeter to the resistance setting.

Touch the multimeter leads to the two terminals on the sensor. If the sensor is working properly, it should have a resistance of around 16,000 ohms at room temperature. If the resistance is significantly higher or lower than this, the sensor may be faulty and need to be replaced.

Conclusion

Knowing the defrost sensor location and how to find it is essential for maintaining your refrigerator or freezer. If you suspect that your defrost sensor is malfunctioning, it is important to test it and replace it if necessary. By doing so, you can ensure that your appliance continues to function properly and keep your food fresh and safe to eat.
