Random fault

A random fault is a fault that occurs as a result of wear or other deterioration. Whereas the time of a particular occurrence of such a fault cannot be determined, the rate at which such faults occur within the equipment population on average can be predicted with accuracy. Manufacturers will often accept random faults as a risk if the chances are virtually negligible. A fault can happen in virtually any object or appliance, Most common with electronics and machinery. For example,an Xbox 360 console will deteriorate over time due to dust built up in the fans, this will cause the Xbox to overheat and cause an error and shut the Xbox down.^{[citation needed]}
