What is an extended warranty?
An extended warranty is an extension of your original manufacturer’s warranty. Most manufacturer’s warranty their products to be free from defects for up to one year from the date of purchase. This warranty virtually guarantees you that if your purchased product fails, CPS will protect you from the high costs of replacement parts and labor necessary to repair your product. Most Consumer Priority Service extended service plans lengthen your product’s coverage for up to an additional 48 months (4 years) to ensure you get years of performance satisfaction from your newly purchased product.
How is this different than the manufacturer's warranty?
A manufacturer's warranty usually offers limited coverage for a limited time, with parts and labor carrying separate lengths of coverage. For example, a common manufacturer warranty of a television might cover a consumer for one full year on parts defects but only 90 days on the high cost of labor involved to change those parts. CPS extended service plans provide comprehensive, long term, even length coverage. This means that should your product fail within your plans coverage time frame, both parts and labor costs are covered.
When does Accidental Damage Coverage begin?
Accidental Damage protection begins 30 days after purchase.
Who will perform the service on my product?
PS works with tens of thousands of authorized service professionals. Each technician is extensively trained by the respective manufacturers to provide service on your products. Authorized technicians must complete annual and bi-annual continued education exams in addition to being well learned in manufacturer supplied update bulletins to ensure their level of expertise is as current as the new products which come to market.
Can I transfer my CPS plan to another person?
Yes, all plans are transferable. Please call (800) 905-0443 for further assistance in transferring your plan. Please note: A transfer fee of $25.00 will apply to all warranty transfers.
Will I have to pay a deductible or any other hidden costs?
Every CPS service plan carries a zero deductible along with low premiums. This means that with a CPS service plan there are no high upfront costs and we are committed to cover 100% parts and labor costs on any authorized claim. Generally, the amount of a deductible is almost always proportional to the amount of the premium charged. In order to have a lower deductible, even as low as $0, the plan holder would generally have to agree to a higher premium. For those who want lower premiums, they must agree to a higher deductible.
How do I file a claim?
Logon to CPS Central where you can initiate a claim on your product. You may also call the toll-free number (800) 905-0443 and have a qualified representative file a claim for you with the information you provide.
