According to Consumer Reports, in the majority of cases, manufacturer warranties provide sufficient coverage for appliances, and there is no need to purchase an additional warranty from the retailer. Consumer Reports data shows that appliances rarely break down within the window covered by retailer extended warranties.
Almost all appliances come with free warranties from the manufacturer. The length of these warranties varies, but as of 2015, most last for 90 days. Retailers offer extended warranties that usually cover products for between one and three years, but these warranties usually cost a fee paid directly to the retailer. Retailer warranties generally start at the time of purchase, not when the manufacturer's warranty expires.
