Most common repairs needed to fix a LG dryer
Heating Element Replacement
When your dryer runs constantly and won’t turn off, an open heating element could be causing the problem. An open (or broken) heating element won’t heat so the dryer will continue to run indefinitely. If the dryer isn’t heating and the cycle runs for a long time, have a Sears Home Services Repair Expert check the dryer. The technician will check the heating element and replace it if it is open.
Electronic Control Board Replacement
When your dryer won’t turn off, a defective control board could be causing the problem. The electronic control board monitors a moisture sensor to detect when clothes are dry. If the dryer continues to run even though clothes are dry, electronic components on the circuit board may have failed. To fix the problem, schedule a Sears Home Services Technician to visit your home and examine the electronic control board. The technician will replace the control board if it’s defective.
Thermistor Replacement
A failed thermistor can keep the dryer from turning off. The thermistor is a temperature sensor that sends signals to the electronic control board to help control heat inside the dryer. A failed thermistor won’t detect the temperature properly so the dryer won’t heat like it should and the dryer cycle won’t end after the normal amount of drying time. When loads take an extremely long time to dry, have a Sears Home Services Technician examine the dryer and replace the thermistor if it’s defective.
Why will my LG dryer not shut off?
When your LG dryer won’t shut off as you open the dryer door, the door switch will likely need replacing.
If the dryer drive motor runs constantly when the dryer is plugged in, a stuck relay on the electronic control board is likely the cause of this failure.
LG dryer won’t shut off when you open the dryer door
Turn the dryer off using the control. If opening the dryer door doesn’t cause the drum light to turn on, the dryer door switch is likely bad.
Unplug the dryer and replace the door switch or have a service technician replace the door switch if you’re unable to replace that part on your own.
Dryer drive motor runs constantly
When the dryer drive motor runs constantly unless you unplug the dryer, the motor relay on the electronic control board is likely stuck.
Sometimes, unplugging the dryer for 2 minutes and then plugging the power cord back in will reset the control and free up the stuck relay. After restoring power, the electronic control board will reboot and reset.
If the drive motor starts and runs after plugging the power cord back in, you’ll likely need to replace the electronic control board.
Here’s a video that shows how to replace the electronic control board in a common type of LG dryer:
If you’re not completely confident that you can replace the dryer electronic control board on your own, schedule dryer repair to have a Sears Home Services technician install a new electronic control board in your dryer for you.

Sears Home Services recommendations for a dryer that won't turn off
When the dryer won't turn off it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dryer failures.
What to look out for with a dryer won't turn off diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dryer problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
An LG dryer that never stops spinning can indicate a defective timer or control board glitch. Letting it run nonstop boosts energy costs and strains internal parts. Seek dryer repair near me to restore normal cycle completion. Protect both your wallet and your dryer’s lifespan.

Excellent service from Daniel
Daniel provided excellent service and was very quick to perform the repair. I have nothing good to say about the warranty program and the LACK of customer service and the inability to contact a human being to talk.
