  5. Replace the back panel and plug the dryer back in to test if it heats up.

Cleaning Or Replacing The Moisture Sensor

The moisture sensor in an LG dryer measures the amount of moisture in clothes and regulates the drying cycle. If the sensor is covered in lint or damaged, it will not work correctly, leading to the NP code issue. Follow these simple steps to clean or replace the moisture sensor:

  1. Unplug the dryer from the power source and locate the moisture sensor. It is typically near the dryer’s lint filter.
  2. Inspect the sensor for lint buildup. If it’s dirty, clean it with a soft brush and a cloth.
  3. If damaged, remove the wires from the sensor and replace it with a new one.
  4. Plug the dryer back in and test it to see if the NP code has disappeared.

Removing Lint Filter And Cleaning

The lint filter is a crucial part of the dryer that prevents fire hazards and improves airflow. When the lint filter is clogged with lint or debris, it can cause the dryer to overheat and show the NP code. Cleaning or replacing the lint filter can help solve the issue. Here are the steps to remove the lint filter in an LG dryer:

  1. Locate the lint filter on the dryer. It is usually on the top panel or inside the dryer door.
  2. Slide the filter out and remove the lint buildup using a soft brush or cloth.
  3. For better cleaning, use warm soapy water to wash the filter. Be sure to let the filter dry before replacing it in the dryer.

Examining and fixing an LG dryer with NP code can seem intimidating and complicated. However, by inspecting each component with care and precision and following the steps mentioned above, it can be a simple and easy process to fix an NP code LG dryer and ensure smooth functioning for years to come.

Troubleshooting With Error Codes

When your LG dryer stops working or displays an error code, it can be frustrating, but don’t worry. Error codes help identify the issue with the appliance and enable users to troubleshoot it without any help. One of the error codes that LG dryers display is “NP” which is related to the thermistor. In this guide, we will discuss how to fix the “NP code” on LG dryer. Keep reading to learn how to troubleshoot with error codes and interpret the “NP error code”.

Interpreting Np Error Code

The “NP” error code on an LG dryer means that the thermistor is faulty or disconnected. Typically, the thermistor, a component that monitors the dryer’s temperature, sends a signal to the dryer’s control board. Your dryer interrupts the cycle if this signal is missing. The “NP” error code is a result of the lack of an appropriate signal.

Checking The Thermistor

Before replacing the thermistor, it’s crucial to check if there is a disconnection or damage to the thermistor’s wiring harness. Follow these steps:

  1. Unplug your dryer from the power source.
  2. Locate the thermistor’s wiring harness. It should be near the dryer’s blower assembly, with two terminals connected to it.
  3. Examine the wiring harness carefully. Look for any damage or visible issues.
  4. If there is no noticeable issue, use a multimeter to check the resistance of the thermistor. The acceptable temperature range is 10,000 Ohms.
  5. If the thermistor’s resistance reading differs from 10,000 Ohms, it’s faulty, and you need to replace it.

If you couldn’t find any issues, then, it could be the control board that has malfunctioned, and it’s time to contact a professional to repair or replace the board.

In conclusion, troubleshooting your LG dryer with error codes is an excellent way of identifying the right repair method. By interpreting the “NP error code” and checking the thermistor, you can resolve the issue and keep your dryer running smoothly.
