Most common repairs needed to fix a LG dryer

Thermal Fuse Replacement

A faulty or blown thermal fuse can prevent the light from working in some dryers. The thermal fuse is a safety device that trips when the dryer overheats. The control board on some dryers will halt all dryer operations when the thermal fuse blows. The light will stop working if the light circuit is affected by the blown thermal fuse. When the dryer light isn’t working, have a Sears Home Services Expert examine your dryer and replace the thermal fuse if it’s blown.

Power Supply Board Replacement

A defective power supply board can prevent the dryer light from working. The power supply board distributes electrical current from the dryer power cord to the electronic control board and other components in the dryer. When the power supply board doesn’t send power to the light board or circuit board that controls the dryer light, the drum light won’t work. When your dryer light isn’t working, have a Sears Home Services Technician visit your home and check the dryer. The technician will replace the power supply board if it’s defective.

Door Switch Replacement

When the dryer light is not working, a failed door switch could be causing the problem. The door switch detects when the dryer door is open or shut. A failed door switch won’t sense when the door is open so the dryer light won’t turn on even through the door is open. Have a Sears Home Services Technician check your dryer when the light isn’t working. The technician will replace the door switch if it is defective.

Sears Home Services recommendations for a dryer light that is not working

When the dryer light is not working 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 light not working 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.
