If you own an LG dryer and have come across the NP error code, don’t panic. This error code indicates a problem with the electrical wiring in your home, specifically that no current is being detected at the heater. While it might seem daunting at first, fixing this error isn’t as complex as it seems. This article will guide you through the steps to troubleshoot and fix an LG Dryer NP Error.


To fix an LG Dryer NP Error, first ensure the power cord is securely plugged into a grounded outlet. Then, reset the dryer by unplugging it for at least 30 minutes. Check for blown fuses or tripped circuit breakers and replace them if necessary. Inspect the power cord and internal wiring for damage and replace if needed. If the error persists, call in a professional repair service. Always prioritize safety and turn off the power before starting any repairs.

Understanding the LG Dryer NP Error

The NP error code on your LG dryer is an indication of an electrical problem. It’s triggered when no current is detected at the heater. This could be due to a range of issues, from power supply problems and control board malfunctions to sensor issues.

Initial signs of an NP error include the dryer’s front LCD turning on, but the heaters not firing up, the dryer spinning and the blower working without producing heat, or the dryer shutting off with the NP code after 5-20 minutes of spinning.

Tools needed to fix an LG Dryer NP Error

To fix an LG Dryer NP Error, arm yourself with a multimeter to check the voltage at the outlet and test the continuity of fuses, circuit breakers, and heating elements. You’ll also need replacement fuses or circuit breakers if these components are causing the NP error, and possibly replacement parts such as the control board or sensors. A screwdriver will come in handy to open the dryer and access the internal components for inspection and replacement.

Steps to Fix an LG Dryer NP Error

Step 1: Inspect the Power Connection

The first step is to ensure that the power cord is securely plugged into a grounded outlet matching the dryer’s rating plate of 240 volts.

Step 2: Reset the Dryer

Unplug the dryer and wait for at least 30 minutes to allow it to cool down. Then, plug it back in. This simple reset can often clear the error.

Step 3: Check for Blown Fuses or Tripped Circuit Breakers

If a blown fuse or tripped circuit breaker is causing the NP error code, replace these components.

Step 4: Inspect the Power Cord and Internal Wiring

A damaged power cord or internal wiring can cause the NP error. If you find any issues here, replace the damaged parts.

Step 5: Consult a Professional

If the error persists after trying these steps, it’s recommended to call in a professional repair service. They will have the expertise and tools necessary to identify and fix any underlying issues with your dryer.

Safety Precautions When Fixing an LG Dryer NP Error

When dealing with electrical appliances, safety is paramount. Always turn off the power at the circuit breaker before starting any repairs. If you’re unsure about any of the steps or feel uncomfortable performing them, it’s best to consult a professional.

In Conclusion

Fixing an LG Dryer NP Error can seem challenging, but with a systematic approach and the right tools, you can get your dryer back to working condition in no time. However, if the error persists after following these steps, don’t hesitate to get professional help. It’s crucial to ensure your appliance is safe and functioning correctly.

Frequently Asked Questions

What does a multimeter do?

A multimeter is an instrument used to measure electrical properties such as voltage, current, and resistance. It can help identify whether there is a problem with the power supply to the dryer.

How can I tell if a fuse is blown or a circuit breaker has tripped?

A blown fuse will often look discolored or cloudy, and may have a broken filament visible through the glass. A tripped circuit breaker, on the other hand, will be in the ‘off’ position on your home’s electrical panel.

Can I replace the control board or sensors myself?

Replacing a control board or sensor can be a complex task and should only be attempted if you’re comfortable with electrical repairs. If not, it’s best to hire a professional.

What should I do if I can’t find a matching outlet for the dryer’s rating plate?

If you can’t find a matching outlet for the dryer’s rating plate, you may need to have a suitable outlet installed by a licensed electrician.

What if the NP error code shows up again after resetting the dryer?

If the NP error code reappears after resetting the dryer, it indicates a persistent issue. You should proceed with the other steps in this guide or consult a professional for help.
