Understanding the Problem

Dealing with an LG dryer that runs continuously with a closed door can be frustrating. Before trying any troubleshooting techniques, it’s essential to understand what could be causing the issue. Here are some possible reasons why your dryer won’t stop unless the door is opened:

  • The door switch is faulty or misaligned.
  • The door sensor is malfunctioning.
  • The dryer controls are not reset properly.
  • The door alignment is off.
  • The lint filter or vent is clogged.
  • The dryer needs professional repair.

Identifying the root cause of the problem can save you time and effort in fixing your LG dryer. In the following sections, we will explore each of these possibilities in detail and provide you with solutions to get your dryer back to working order.

Checking the Door Switch

If your LG dryer won’t stop running unless the door is opened, a faulty door switch might be the culprit. The door switch is a small device located on the dryer’s front panel or inside the door frame. When you close the door, the switch is activated, signaling the dryer to stop. If the door switch is malfunctioning, the dryer won’t turn off properly even when the door is closed.

To check the door switch:

  1. Unplug the dryer from the electrical outlet to ensure your safety.
  2. Locate the door switch and remove it from the dryer. Refer to your owner’s manual for guidance if needed.
  3. Use a multimeter to test the switch for continuity. Set the multimeter to the ohms function and touch the probes to the switch’s terminals. A reading of zero ohms means the switch is working correctly, while an infinite reading indicates a faulty switch that needs to be replaced.
  4. If the switch is working correctly, ensure it’s properly aligned with the door. If it’s not, adjust it accordingly and try the dryer again.
  5. If the switch is faulty, replace it with a new one. You can find replacement parts online or at your local appliance store.

Inspecting the Door Sensor

If the door switch is not the culprit behind your LG dryer not turning off when the door is closed, the next component to check is the door sensor. Some LG dryers use a sensor to detect the door’s position, sending a signal to the dryer to stop running when the door is open. If the sensor fails, the dryer may continue running even with the door closed, leading to the issue you are experiencing.

To inspect the door sensor, start by unplugging your LG dryer and locating the sensor. The sensor is usually located near the dryer door frame, and it should have two wires connected to it. Once you find the sensor, check for any visible signs of damage or wear. If the sensor appears damaged, you should replace it.

If the sensor looks undamaged, use a multimeter to test it for continuity. Set the multimeter to the lowest resistance setting and touch the prongs to the sensor’s wires. The multimeter should display a reading of zero or close to it. If the multimeter shows a different reading or no reading at all, the sensor is likely faulty, and you should replace it.

If the sensor appears to be in good condition and displays proper continuity, the problem may be caused by a wiring issue. Check the wires connected to the sensor for any signs of damage or loose connections. If you find any issues, repair or replace the wiring as necessary.

“A faulty door sensor can cause the LG dryer to run non-stop with a closed door, leading to a frustrating situation. By inspecting and troubleshooting the door sensor, you can quickly identify and resolve the issue.”

Resetting the Dryer Controls

If your LG dryer keeps running unless the door is open, try resetting the controls to see if it resolves the issue. This is a simple process that can fix minor glitches causing the problem.

Here’s how to reset the dryer controls:

  1. Press the “Power” button to turn off the dryer.
  2. Unplug the dryer from the power source or turn off the circuit breaker that supplies electricity to the dryer.
  3. Wait at least 5 minutes to allow the dryer to reset.
  4. Plug the dryer back in or turn on the circuit breaker and turn on the dryer.

If the dryer still runs continuously with the door closed, you may need to try other troubleshooting techniques or seek professional repair services.

Adjusting the Door Alignment

If the door alignment of your LG dryer is off, it can cause the door switch to not signal the dryer to turn off properly, resulting in the dryer continuing to run even when the door is closed. Here’s how you can adjust the door alignment:

  1. Unplug the dryer and locate the door hinge screws on the inside of the dryer door frame.
  2. Loosen the screws with a screwdriver, but do not remove them completely.
  3. Adjust the door by moving it up or down until it aligns with the door switch, ensuring that the door can still open and close properly.
  4. Tighten the screws back into place, and plug the dryer back in to test if the door switch is now functioning properly.

Remember to always prioritize safety by unplugging your dryer before making any adjustments.

Cleaning the Lint Filter and Vent

Lint Filter and Vent Cleaning

A clogged lint filter or vent can cause your LG dryer to malfunction, including not turning off when the door is closed. Over time, lint can build up in the filter and vent, obstructing airflow and causing your dryer to overheat. This can lead to potential safety hazards and damage to your appliance.

To prevent these issues, it’s important to regularly clean the lint filter and vent. Here are the steps to follow:

  1. Remove the lint filter from the dryer and clean it with warm, soapy water. Rinse it thoroughly and let it dry completely before placing it back into the dryer.
  2. Locate the vent at the back of the dryer and disconnect it from the wall or ductwork.
  3. Clean the vent with a brush or vacuum, making sure to remove any buildup of lint or debris.
  4. Reconnect the vent to the wall or ductwork. Make sure that it fits securely and is not kinked or damaged.

Regularly cleaning the lint filter and vent can help improve the airflow in your LG dryer and prevent potential safety hazards. Aim to clean the lint filter after every use and the vent at least once a year, depending on how often you use your dryer.
