What is Sensor Dry in an LG dryer, and how does it work?
Sensor Dry is a feature in LG dryers that uses moisture sensors to detect the level of moisture in the laundry. The dryer then adjusts the drying time automatically to ensure that clothes come out perfectly dry, without the risk of over-drying. This not only saves energy but also helps in reducing wear and tear on your garments.
The moisture sensors are typically located in the dryer drum and work by monitoring the moisture content in the clothes. When the sensors detect that the clothes are sufficiently dry, the dryer stops the cycle, ensuring efficient drying times. If there is an issue with this feature, it can result in wet clothes after the cycle ends, indicating that troubleshooting may be necessary.
What are common reasons why the Sensor Dry feature may not work?
There are several reasons why the Sensor Dry feature may not function properly. One common issue is the presence of lint or debris blocking the moisture sensors. If the sensors are covered, they may not accurately detect the moisture in your clothes, leading to insufficient drying times.
Another reason could be related to the dryer’s settings. If the selected drying cycle doesn’t utilize the Sensor Dry feature or if the dryer is overloaded, the sensors may struggle to function correctly.
