Whirlpool Defrost Thermostat: A Comprehensive Guide

If you own a Whirlpool refrigerator, you may have heard of the defrost thermostat. This small but essential component plays a crucial role in keeping your fridge running smoothly. In this article, we’ll take a closer look at what the Whirlpool defrost thermostat is, how it works, and why it’s important.

What is a Defrost Thermostat?

A defrost thermostat is a temperature-sensitive switch that controls the defrost cycle in a refrigerator. It’s located in the freezer compartment and is responsible for turning off the defrost heater when the temperature reaches a certain point. This prevents the freezer from getting too warm and ensures that the evaporator coils don’t freeze over.

How Does a Defrost Thermostat Work?

The defrost thermostat is connected to the defrost heater and the evaporator coils. When the temperature in the freezer drops below a certain point, the thermostat closes, allowing electricity to flow to the defrost heater. The heater then warms up the evaporator coils, melting any ice that has accumulated on them.

Once the temperature reaches a certain point, the thermostat opens again, cutting off the electricity to the defrost heater. This allows the freezer to return to its normal temperature and prevents the evaporator coils from overheating.

Why is the Defrost Thermostat Important?

The defrost thermostat is an essential component of any refrigerator. Without it, the evaporator coils would freeze over, preventing the fridge from cooling properly. This could lead to spoiled food and a malfunctioning appliance.

In addition, a faulty defrost thermostat can cause a number of problems. If the thermostat fails to open, the defrost heater will continue to run, causing the evaporator coils to overheat. This can damage the coils and lead to a costly repair bill.

On the other hand, if the thermostat fails to close, the defrost heater won’t turn on, and the evaporator coils will freeze over. This can cause the freezer to become too warm and lead to spoiled food.

Conclusion

The Whirlpool defrost thermostat is a small but essential component of any refrigerator. It plays a crucial role in keeping the freezer from freezing over and ensuring that the fridge stays cool. If you suspect that your defrost thermostat is faulty, it’s important to have it replaced as soon as possible to prevent any further damage to your appliance.
