Most common repairs needed to fix a LG dryer
Sensor Replacement
If your dryer's "clean filter" light won't turn off, it could be due to a failed sensor. The sensor detects the level of lint build-up in the filter and signals the control board to turn on the light when the filter needs cleaning. If the sensor is malfunctioning, it may continuously signal that the filter is dirty, even when it has been cleaned. If you suspect the sensor is at fault, schedule an in-home repair with a Sears Home Services technician.
Blower Motor Replacement
A clogged or damaged blower wheel could be the reason your dryer's "clean filter" light won't turn off. The blower wheel circulates air through the dryer and lint filter. If the blower wheel is obstructed by lint or debris, it can reduce airflow, causing the sensor to detect a dirty filter even when it's clean. The dryer might take longer to dry clothes or the "clean filter" light stays on. To address this issue, inspect the blower wheel for any obstructions or damage.
Electronic Control Board Replacement
The electronic control board processes signals from various sensors, including the one monitoring the filter. If the control board is faulty, it might incorrectly interpret the sensor's signal, causing the light to remain on even when the filter is clean. Diagnosing a control board issue can be complex and requires professional expertise. If you suspect the electronic control board is the problem, schedule an in-home repair appointment with Sears Home Services to have a technician diagnose and replace the faulty control board.

Sears Home Services recommendations for a dryer clean filter light won't turn off problem
When a dryer clean filter light 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 clean filter light 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.
If your LG dryer’s clean-filter indicator stays lit, the sensor or board may be misreading airflow. Even with a spotless filter, the alarm may persist. Rather than ignoring it, consult dryer repair near me to verify sensor accuracy. A quick tweak restores your dryer’s normal prompts.

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.

Frequently Asked Questions
Why won’t the “clean filter” light on my LG dryer turn off?
An obstructed lint screen, a sensor error, or a control board glitch may keep the light on. Make sure the lint filter is fully seated and free of debris.
How do I properly clean the lint screen?
Remove the screen, wash it with warm soapy water to remove fabric softener residue, then let it dry thoroughly before reinserting.
Does resetting the control board fix the light issue?
Sometimes, yes. Try unplugging the dryer for a minute, then reconnecting power to reset the control board. If the light remains on, further inspection is needed.
When is professional help needed for a persistent “clean filter” light?
If thorough cleaning and a quick reset don’t clear the message, the sensor or control board could be malfunctioning. A technician can diagnose and replace faulty parts.
