Can a Manufacturer Void Your Warranty? 5 Mistakes to Avoid
When you buy a new device, fitness equipment, appliance, or piece of furniture, it likely comes with a manufacturer warranty. This limited warranty is primarily designed to cover defects in materials or workmanship, giving you peace of mind in case something goes wrong due to manufacturing issues.
What many people don’t realize is that a warranty can be voided, meaning the manufacturer may refuse to honor all or part of the warranty if the product hasn’t been used, maintained, or repaired according to their stated terms.
In other words, a “voided” warranty is one that’s no longer valid in full or in part, depending on the situation. This doesn’t always mean your entire warranty is canceled; sometimes, only certain claims are denied or specific components lose coverage, while others remain protected.
That’s right: your warranty can be affected, leaving you responsible for costly repairs or replacements that might otherwise have been covered. Below are some of the most common and easily avoidable mistakes that can cause your warranty to be voided or restricted.

- DIY Repairs or Unauthorized Service Providers
- If you try to fix your device yourself or take it to a repair shop that isn’t authorized by the manufacturer, you could unknowingly void your warranty.
-
- Avoid it: Always check with the manufacturer before starting a repair or using third-party services.
- Avoid it: Always check with the manufacturer before starting a repair or using third-party services.
- Accidental Damage
- Most manufacturer warranties only cover defects from the factory, not accidents. So if you drop your laptop, spill coffee on your couch, or crack your treadmill’s screen, your warranty likely won’t help.
-
- Avoid it: Consider a protection plan that includes accidental damage, like Safeware offers for many product types, to bridge the gap.
- Using Non-OEM Parts or Accessories
- Using off-brand or incompatible chargers, batteries, or parts can sometimes damage your product and give the manufacturer a reason to void your warranty.
-
- Avoid it: Stick to original manufacturer accessories, especially when it comes to sensitive components like batteries or charging cables.
- Failing to Register the Product (or Keep Proof of Purchase)
- Some manufacturers require you to register your product or show a valid receipt to activate or claim warranty coverage.
-
- Avoid it: Register your product right after purchase and save your receipt in a safe place, digital copies work too.
- Misuse or Neglect
- Warranties often include language about “normal use.” If your product shows signs of misuse or intentional damage, it could be grounds for denial.
-
- Avoid it: Use your products according to the manufacturer’s guidelines and store them properly.
Remember: These aren’t all the reasons a warranty can be voided, just some of the most common ones. Always review your product’s specific warranty terms and conditions to understand what’s covered and what could affect your protection.
Not every situation results in your entire warranty being canceled. For example, repairing the stuffing on a couch yourself might void coverage for the cushions or seams, but the frame could still be protected.
Knowing the details of your warranty can help you avoid small mistakes that lead to big costs later on.
