You might have wondered why your dryer keeps shutting down after a few minutes of starting its cycle.

Or perhaps, it keeps spinning even after your clothes have dried, making them overdried.

Dryers are manufactured to save your time during laundry but can be frustrating if it gives you problems.

This article will help you discover many things about your dryer and why it refuses to work normally.

When testing your LG dryer’s moisture sensor, you first need to place dry clothes inside the dryer. Then, turn the dryer on. If your dryer is working well, it will run for a few minutes and then shut down. So, the next step is to place wet clothes inside the dryer and turn it on just like you did the first time. 

How To Test A Dryer Moisture Sensor?

The function of the moisture sensor in your dryer is to help you detect moisture in your clothes.

It checks how damp your clothes are inside the dryer, and it automatically notifies your dryer to stop whenever your clothes dry completely.

One of the maintenance your dryer needs is to test its moisture sensor from time to time.

This will help you discover whenever it’s faulty, making laundry more straightforward and stress-free.

Therefore, below are the steps you must follow when carrying out a moisture sensor test on your dryer;

  • Place dry clothes inside your dryer and turn it on.
  • Your dryer will start working, and after a few moments, it will shut down.
  • Remove the dry clothes, place damp ones inside the dryer, and then turn it on.
  • The dryer will run until the clothes are dried thoroughly.

In short, if the dryer runs for some minutes and doesn’t shut down, that means it’s operating efficiently and it passes the test.
