In that case, the merchant would have to remedy the breach by supplying a working oven or by paying damages. An implied warranty of merchantability is a promise that a product or good is fit for its ordinary purpose. An implied warranty of fitness for a particular purpose is a promise, again implied by law, by a merchant who knows that a buyer intends to use a product or good for a particular purpose, and has reason to know that the buyer is relying on the merchant's knowledge or expertise, that the product or good is suitable for the buyer's special use or particular purpose. For example, assume a buyer tells an appliance retailer that he wants to purchase a washing machine that can handle 15 pounds of laundry at a time. If the retailer recommends a particular model, and the customer buys that model on the strength of the recommendation, the law says that the retailer has made a warranty of fitness for a particular purpose.
Implied warranties are promises about the condition of products at the time they are sold.
They are not guarantees that a product will last for any specific length of time, and they do not cover everything that can possibly go wrong with a product. For example, implied warranties do not cover problems such as those caused by abuse, misuse, ordinary wear, failure to follow directions, or improper maintenance. Most state law statutes of limitations for breach of either an express or an implied warranty are four years from date of purchase. This means that buyers have four years in which to discover and seek a remedy for problems that were present in the product at the time it was sold. An implied warranty of merchantability on a used product is a promise that it can be used as expected, given its age, type and price range.
