What does the Whirlpool warranty cover and for how long?

Whirlpool provides a one-year limited warranty from the date of purchase, covering Factory Specified Replacement Parts and repair labor to correct defects in materials or workmanship, provided the appliance is installed, operated, and maintained according to instructions. The warranty does not cover improper venting service calls, cosmetic damage (unless reported within 30 days), misuse, unauthorized modifications, or service calls to correct installation issues. Proof of original purchase date is required to obtain warranty service. (Page 13)
