What is the warranty?

Asked by: Concernedhomeowner
Hello Concernedhomerowner, we apologize that the manufacturer warranty information was not present on product page and have made steps to get that resolved, in the interim please review the manufacturer's use and care manual directly from their website which outlines the details of their limited 1 year and limited extended warranties. I have provided the link to the file below. Additionally, the Home Depot offers a 3-Year protection plan that can be added to your order which begins after the 1 year limited manufacturer's warranty. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot! If you are not able to access that PDF file, you may also go directly to Williams' site where the file can be found at the following URL.
