For issues that are covered under the warranty, Emerson covers the cost of any necessary repairs due to a defect in parts or workmanship, according to the owner's manual. Most Emerson microwaves are covered by a one-year limited parts and labor warranty, as of 2015. In addition, the microwaves feature a seven-year limited replacement warranty on the magnetron.
Although Emerson is obligated to provide a replacement magnetron at no cost to the customer if it fails within seven years, the company only covers the cost of labor for 12 months from the original date of purchase. The warranty only covers a manufacturing defect or problem that occurred under normal use and conditions and is only valid for the original owner. The warranty is also only valid for products used within the United States.
If warranty service is necessary, the customer must either take the microwave to an Emerson authorized, independent service center or mail the product to a regional service center. In order for Emerson to cover the costs of the repair, the service center must verify both the manufacturer defect and the original date of purchase. For products shipped to a regional service center, it is necessary to enclose a check or money order for $15 to cover the cost of return shipping, as of 2015.
