When a manufacturer provides a full warranty with a product, it is the manufacturer's responsibility to

Replace or repair a faulty product.

Replace or repair a faulty product. A warranty is a promise made by the seller to the consumer that the seller will repair or replace a product that does not perform as expected. A full warranty provides that if the product does not work properly, is defective, or does not live up to the warranty, it must be made good within a reasonable time. The company providing the warranty may not put time limits on any implied warranties the product may have. A limited warranty would only cover specific parts rather than the whole product. Most warranties state that improper use or handling of the product will void the warranty.
