Visit the Samsung website and use the service location finder to see if there is an authorized service provider near you. There are also other appliance repair companies, such as Sears Home Services, that fix Samsung dryers, with most companies able to provide service at your home.
Having your Samsung dryer model number ready is helpful but is not essential when looking online for an appliance repair provider. As of January 2015, the service location finder on Samsung's website is on the "Owners and Support" drop-down menu under "Get Support." After clicking through to the "Get Support" page, find the "Schedule a Repair" section in the center of the page, where you can choose between scheduling service, tracking service and finding a location. Also on the "Get Support" page, Samsung gives the option of identifying your dryer model with the help of pictures if you don't have your model number.
If you visit the Sears Home Services website, you can submit a service request online by entering your zip code and specifying the type of service needed. Again, having your dryer model number handy is helpful. If you prefer to schedule service over the phone, Sears provides a phone number: 1-800-424-2047.
