To sell an old appliance, find places to advertise the appliance and use a good description of its price and condition, and provide your contact information. Hang print advertisements in public places with the property owner's permission or use a website where personal goods are advertised for sale.
Another way to sell an old appliance is through a garage sale or a swap meet. These are common sales for price negotiation, so be prepared to accept an offer lower than you hoped to get. Buy advertising space in the classified section of a local newspaper and include contact information, the price and the condition. Run the advertisement on a weekend to reach more people; more people read the weekend edition of a newspaper. Advertise the item at a local university or community college by hanging a printout on a board in the student union or placing an advertisement in the college newspaper or newsletter.
If applicable, hang a printout for a refrigerator or freezer at a local conservation club, rod and gun club or hunting preserve to appeal to hunters who often convert used refrigerators into meat smokers. Advertise a used freezer at a feed store where farmers or hunters shop, as many require extra freezer space to store food. Some recycling centers buy used appliances or refer you to other organizations that do. If all else fails, sell the appliance as scrap metal or to a repair shop for parts.
