Understanding the Role of a Dryer Thermostat

The LG dryer thermostat is an important part for the dryer that monitors the drying temperature. It senses the heat in the dryer drum and tells the heating element to turn on or off as required. This regulation ensures that the dryer works at the optimum temperature for drying.

It can cause significant issues when the thermostat malfunctions as it will create an imbalance in the temperature of your home. For example, if the LG dryer high limit thermostat does not work, it may not be able to measure temperature properly and the unit may overheat. A bad thermostat could cause the dryer to heat up at all, thereby leaving your clothes damp after a complete drying cycle. Extended drying times can be quite inconvenient to some users, especially when it comes to daily routines. 

Common Thermostat Problems with LG Dryers

Thermostat problems on LG dryers can be compounded by problems with the thermal fuse or heating elements. If you discover that your LG dryer not working properly is associated with these components, it is essential to troubleshoot accordingly.

  • LG dryer will not heat: The most common problem is that the LG dryer will not heat correctly. In most cases, this problem is caused by a faulty thermostat. If the high limit thermostat keeps tripping, the dryer will stop heating in the middle of the cycle, leaving your clothes wet at the end of the drying session.

  • LG ThinQ dryer not drying: Many users say that their LG ThinQ dryer is not drying effectively. If clothes are wet even when the dryer is running, the thermostat may not be regulating temperature properly. It could result in an overheating situation, and as a safety measure, the LG dryer high limit thermostat will keep tripping.

  • Dryer overheating: If the thermostat is not working properly, overheating is a serious condition. The LG dryer high limit thermostat can trip if the dryer is constantly running hot and the machine will not operate safely. The result is longer drying times and more energy use as the dryer works to keep the desired temperature.

Troubleshooting Thermostat Issues

A malfunctioning thermostat may be the cause of problems with drying efficiency. Here’s how to troubleshoot and fix your LG dryer’s thermostat issues.

1.  How to reset LG dryer thermostat

  • Safety precautions: Unplug the LG dryer before beginning any work on it to avoid electrical hazards.

  • Unplug the dryer: Always unplug the dryer before doing any repairs; safety comes first.

  • Locate the thermostat: The LG dryer thermostat is usually situated close to the heating element or inside the control panel area. The location of the LG dryer thermostat will be in the specific LG dryer manual.

  • Inspect the thermostat: There may also be visible signs of damage or wearing. If you need to reset the LG dryer high limit thermostat, find a small reset button on it.

  • Reset the thermostat: If there is a reset button, press it to reset the thermostat. If there is no reset button, you may have to replace the thermostat if it is faulty.

2. Cleaning the lint filter and ventilation system

The thermostat can be affected greatly by blockages in your dryer’s ventilation system. If lint builds up, the LG dryer thermostat can misread temperatures and dry inefficiently.

  • Clean the lint filter: After each use, take out the lint filter and make sure you clean it well so that it can allow for the best airflow.

  • Check the vent hose: Remove the vent hose and unplug the dryer. Remove any lint and debris from the hose by vacuuming or brushing.

  • Inspect the vent outlet: Make sure the vent outlet is not blocked. This will keep the proper airflow and prevent overheating, which can result in malfunction of the LG dryer thermostat.

  • Ensuring proper dryer load: Straining your dryer’s components and affecting temperature regulation can lead to thermostat problems.

3. Impact of overloading on temperature regulation:

  •  An LG dryer high limit thermostat can trip and shut down the heating element when the dryer is overloaded because the dryer cannot circulate hot air effectively.

  •  Fill the dryer no more than three quarters full to keep it efficient. It allows for effective circulation of hot air and makes sure that the LG dryer thermostat works fine.
