3 Things to Know About Third-Party Parts and Warranties

Using a third-party part does not automatically void your warranty The Magnuson-Moss Warranty Act in the US makes it illegal for companies to void your warranty just because you used a third-party part, unless they can prove the part caused the failure.

The part you use can void coverage for damage it causes If a cheap third-party vacuum filter lets fine dust through and burns out the motor, that motor repair is on you. But your warranty for unrelated issues, like a broken switch, still stands.

Companies often bluff to scare you into buying their accessories Don’t fall for it. Keep your receipts and avoid using parts that are obviously wrong for the job. A little common sense and consumer law knowledge is all you need.
