Because Whirlpool coverage stays with the first owner, the remaining warranty probably did not follow the sale to you, even if the calendar time has not expired. To confirm, decode the serial with our free tool for the manufacture date, then call the Whirlpool line at 800-253-1301 (labor help is limited to 1 year from install).
