A warrantor does not make its written or implied warranty conditional on the consumer using any article or service identified by brand, trade or corporate name, unless that article or service is provided free under the warranty or the FTC has granted a waiver after publication in the Federal Register (showing the product works properly only with it and that the waiver is in the public interest). The warrantor does not void coverage because non-warranty maintenance or repair used third-party parts or independent service, and does not supply warranty parts in a way that stops the consumer choosing who installs them; it may still exclude defects actually caused by unauthorised parts or service where it can show that cause.
