    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.

    How is the won't turn off problem fixed?

However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

    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.

    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.

    Dryer service

    He was professional and polite. I didn't call back later that afternoon, although he replaced a thermostat the smart dry timer doesn't work as I was still having the same issue. The lady said she would email him and have him return. Never heard from anyone else.
