Most models of Sharp air purifiers and microwaves come with some form of limited warranty as of 2015. These are the only two types of home appliances that are listed for sale in the United States on the Sharp website.
Sharp features a one year limited parts and labor warranty on most of its microwaves, including the KB-6525 Easy Open Microwave Drawer. This warranty guarantees against any defects in materials or workmanship for one year from the date of purchase. If any functional part of the microwave is found defective in this period, Sharp covers the costs of any replacement parts and in-home service necessary to repair the defect. In the event that it cannot be repaired, Sharp may then replace the microwave with a similar model. In addition, most microwaves feature an additional five year parts warranty on the magnetron tube.
Most Sharp air purifiers, such as the IG-BC2UB Ultra-High Density Plasmacluster Ion Generator car air purifier, feature a similar one year parts and labor warranty that begins on the date of purchase. The warranty does not cover damage to the product's appearance, filters or accessories. It also does not cover products used for rental or commercial purposes and is only applicable to the original owner.
