Taking a phone, laptop or watch to an independent repair shop does not automatically cancel the manufacturer’s warranty under US federal consumer law, according to the Federal Trade Commission (FTC). This article explains what the agency has said, where the exceptions sit and what remains unsettled.
What the FTC has actually said
The FTC enforces the Magnuson-Moss Warranty Act, a federal law passed to help buyers understand and use product warranties. In a March 2019 business blog post, the agency said the law “prohibits manufacturers from conditioning warranty coverage on the use of particular products or services.”
In the same post, FTC staff described a reply they gave to a commenter on March 18, 2019. Staff wrote that companies generally cannot void a warranty or deny coverage solely because a consumer used a non-company part or an unauthorized service provider. That is the core rule, and most of the rest of this article is about its edges.
The FTC’s statements concern the United States. Other countries have their own warranty and repair rules, and state laws can add to the federal baseline.
Does using a third-party part void the warranty?
Generally not, if the only reason given is the use of that part. The FTC staff reply named two exceptions:
- The company provides the part or service for free under the warranty.
- The company has obtained a waiver from the FTC.
Outside those cases, a warranty term that says something like “use only our dealers” or “use only our replacement parts” is the kind of condition the anti-tying provision is meant to stop. “Tying” here means making a benefit, such as warranty coverage, depend on buying something else from the same company.
What a manufacturer can still do
The rule does not make a warranty unconditional. The same FTC staff reply said a company “may, however, disclaim warranty coverage for defects or damage caused by the use of unauthorized parts” or service.
The distinction is between cause and category. Consider this worked example, which is illustrative rather than legal analysis:
| Situation | General position described by the FTC |
|---|---|
| A phone’s speaker fails. The screen was replaced earlier by an independent shop. | The screen swap alone should not be a reason to deny coverage for an unrelated speaker defect. |
| A phone’s display fails right after a poorly fitted aftermarket part damaged the connector. | The company may be able to decline coverage for damage caused by that part or service. |
| A warranty says any third-party part voids all coverage. | This is the kind of blanket term the FTC has challenged. |
Where a dispute turns on whether a repair caused a fault, the facts of the individual case matter, and the examples above are not a prediction of any specific outcome.
Why did the FTC take this up?
The agency held a workshop called “Nixing the Fix” on July 16, 2019, and kept its public comment record open until September 16, 2019. A May 2021 report to Congress followed. Its questions included whether design choices such as glue, non-standard screws or proprietary diagnostic software make independent repair harder.
According to the FTC’s later description of that report, it found “scant evidence that repair restrictions are necessary” to protect repair workers and consumers from injuries. It also found no empirical evidence that independent repair shops are more or less likely than authorized shops to misuse customer data, and no evidence that giving independent shops access to diagnostics and firmware patches would create cybersecurity risks.
Manufacturers have offered those concerns, along with intellectual property protection, as reasons for restrictions. The FTC’s position is that the evidence it reviewed did not support them. That is a regulator’s finding, not the last word, and companies continue to make their case in policy debates.
What happened when the FTC enforced it?
The FTC followed the report with a 2021 policy statement saying it would prioritize action against illegal repair restrictions. According to the agency, three enforcement actions followed in 2022, involving makers of grills, motorcycles and outdoor power equipment.
The best documented example in the FTC’s July 7, 2022 announcement is Weber-Stephen Products, a grill maker. The FTC alleged that Weber’s warranty said it would be void if customers used third-party parts, which it said limited choices, steered buyers toward more expensive Weber parts and disadvantaged independent repairers.
Under the proposed order, Weber had to stop saying that third-party parts void the warranty and add this sentence to its warranty: “Using third-party parts will not void this warranty.” Future violations could bring civil penalties of up to $46,517 per violation. The Commission voted 5-0 to issue the complaint and accept the settlement, which was subject to 30 days of public comment before being finalized.
Those cases involved household and outdoor products rather than phones. They show how the agency reads the law, but the announcements describe the warranty terms of those companies, not the terms of any particular electronics maker.
Are “warranty void if removed” stickers legal?
The FTC pages reviewed for this article did not address warranty stickers by name, so no firm statement can be made here. The general principle in the staff reply points one way: a company cannot void a warranty solely because of the use of an outside part or service. Whether a specific sticker or contract term crosses that line depends on its wording and on how the company applies it.
A reader facing a refusal can ask the company to explain, in writing, which defect it believes the repair caused. The FTC accepts consumer complaints, and a state consumer protection office may also be an option.
How do software locks fit in?
Warranty terms are only one barrier. Some devices use software locks, which the law calls technological protection measures, to restrict access to firmware or diagnostic tools. In a March 14, 2024 announcement, the FTC and the Department of Justice’s Antitrust Division said in a joint comment to the US Copyright Office that these locks “can also be used to prevent non-infringing third-party repair.”
The agencies supported renewing and expanding exemptions to the Digital Millennium Copyright Act’s ban on circumventing such measures. Their stated view was that this would promote competition in replacement parts, repair and maintenance and make fixing owned items easier and cheaper. The comment was a recommendation to the Copyright Office, which makes its own decision, and the announcement does not by itself change what any device manufacturer must provide.
What should an owner look for in a warranty?
Reading the document itself is the most reliable step. A few plain checks help:
- What is covered and for how long. The warranty states the period and the kinds of defects included.
- Any language about outside parts or service. A term that conditions coverage on using the company’s own parts or dealers is the kind the FTC has described as prohibited, unless the exceptions apply.
- Any language about damage. Terms excluding damage caused by unauthorized parts or service are the kind staff said companies may use.
- Records. Keeping receipts and a written description of the repair makes it easier to show what was done and by whom if a dispute arises.
None of this replaces reading the warranty in full, and the wording differs between products and sellers.
What this does not cover
Several limits are worth keeping in mind:
- Accidental damage and wear. Standard warranties usually cover defects, not drops or spills, whoever repairs the device.
- Extended plans and insurance. Paid protection plans may carry separate terms and are not the same as the manufacturer’s basic warranty.
- Safety. Batteries are a sensitive part. For background on why they age and what that means for replacement, see our explainer on battery health.
- Design. Sealed or glued designs can make repair difficult even where the law is on the owner’s side, a trade-off visible in complex hardware such as foldable phones.
- Other regions. Rules such as the European Union’s common charger requirements show a more prescriptive approach to hardware than US law generally takes.
Conclusion: a rule about cause, not about who held the screwdriver
According to the FTC, a US manufacturer generally cannot void a warranty solely because an owner used an outside part or an independent repair shop, with narrow exceptions for free parts or an FTC waiver. A company can still decline to cover damage that the outside part or service actually caused. Questions that remain open include how individual device makers word their terms and how courts and agencies treat stickers and software locks. Anyone with a specific dispute should read their own warranty document and consider advice suited to their situation.
