    Most common repairs needed to fix a Samsung dryer

    Thermal Fuse Replacement

    A faulty or blown thermal fuse can keep the dryer from starting. The thermal fuse is a safety device mounted on the blower housing that trips when the dryer overheats. The thermal fuse in most electric dryers prevents the motor from running. In some gas dryers, a blown thermal fuse will also prevent the motor from running. A clogged exhaust vent system often causes the dryer to overheat and the thermal fuse to blow. When the dryer won’t run, have a Sears Home Services Technician visit your home and fix the dryer. The technician will replace the thermal fuse if it’s blown.


    Door Switch Replacement

    If your dryer won’t start a cycle, a failed door switch could be causing the problem. The door switch detects when the dryer door is shut. A failed door switch won’t sense whether the door is closed properly. The dryer won’t start even through the door is closed when the door switch is bad. Have a Sears Home Services Technician check your dryer when it won’t start. The technician will replace the door switch if it is defective.

    Drum Belt Replacement

    When your dryer won’t start a cycle, a broken drum belt could be causing the problem. The drum belt wraps around the dryer drum and connects to the drive motor pulley. The drive motor rotates the belt to spin the drum. Over time, the drum belt becomes worn and can break. A switch on the idler pulley prevents the motor from starting when it senses that the drive belt is broken. When the dryer won’t start, have a Sears Home Services Technician check your dryer and replace the drum belt if it’s broken.

    Sears Home Services recommendations for a dryer that won't start cycle

    When the dryer won't start a cycle 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 start a cycle 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.
