Your LG dryer light won’t turn off due to an electrical issue, faulty door switch, or malfunctioning timer control mechanism. You can resolve these problems by performing a hard reset or replacing the defective hardware. 

In this article, I’ll discuss the common reasons why your LG dryer’s light won’t turn off. I’ll also provide some easy solutions for each cause. Let’s get started!  

1. Electrical Issues

Like most other appliances, your LG dryer can experience electrical glitches, which may cause the light not to turn off automatically once the drying cycle is complete.

These electrical glitches can manifest in different ways, from the dryer turning off on itself, the dryer refusing to turn on, and more. In some cases, the glitch can affect the drum light in your dryer, preventing it from turning off. 

Our article entitled “What to do When your LG Dryer Reset Button Keeps Tripping” explains more about how electrical faults and glitches can affect your dryer.

How To Fix

The best way to fix an electrical fault or error is to perform a reset, and there are various ways to do this on an LG dryer. 

The easiest way to reset your LG dryer involves the following easy steps:

  1. Press the power button on the dryer to turn it off.
  2. Disconnect the LG dryer from the electrical outlet.
  3. Press and hold the Start button for approximately 5 seconds.
  4. Reconnect the LG dryer to the power outlet.
  5. Start the dryer and check whether the problem has been resolved.

If this approach doesn’t work, you can perform a hard reset. Follow these simple steps to hard reset your LG dryer:

  1. Turn off your LG dryer’s circuit breaker.
  2. Unplug the dryer from the power source with the circuit breaker off.
  3. Press and hold the Start button for about 5 seconds.
  4. Press and hold the Play/Pause button for about 5 seconds.
  5. Reconnect the dryer to the electrical outlet and turn the circuit breaker back on.

This approach is recommended for troubleshooting electrical issues. 

2. Defective Door Switch

When the light on the dryer doesn’t automatically turn off, the dryer is still on and hasn’t turned off automatically. This could be due to a defective door switch.

A door switch is an on-and-off mechanism that prevents the dryer from operating once you open the door, and most of these switches measure about an inch (2.5 cm) long. 

How To Fix

To resolve this issue, first establish whether the door switch is defective. You can do this by removing the door switch and testing it with a digital multimeter. Watch the video below to learn more about how to check for a defective door switch using a multimeter: 

Once you’ve established that the door switch is broken, you should replace it. However, if the door switch isn’t defective and the lamp remains on, it may be due to a faulty timer control mechanism. 

You can replace the door switch yourself or call a technician for assistance.

3. Malfunctioning Timer Control

A malfunctioning timer control can prevent your LG dryer from completely turning off, even with the door open. A timer performs the critical task of regulating the drying cycle to keep your clothes from getting damaged due to a prolonged drying cycle. 

A malfunction of this timer will prevent the dryer from turning off, leaving the light on. Most LG dryers have a Wrinkle Care setting that keeps the dryer on for up to 180 minutes after the cycle is complete.

A crucial first step is determining whether this option is enabled, which may prolong the drying cycle. If the Wrinkle Care option hasn’t been activated, but the light remains on, it may be time to check the timer control.

How To Fix

To fix a faulty timer control mechanism, simply remove the timer from the dryer and replace it with a new part. You can buy a replacement part online or from a local appliance spare parts store. Alternatively, call a technician and have them replace the old part. 


There are various reasons why your LG dryer’s light remains on even after the cycle is complete. In summary, it could be due to the following:

  • An electrical fault
  • A faulty door switch
  • A malfunctioning timer control mechanism

A simple reset usually resolves electrical glitches. If this doesn’t work, assess the hardware components, such as the timer control and the door switch, which may prevent the dryer from properly switching off.
