PartSelect, Stuccu and AppliancePartsPros are online stores that offer replacement Whirlpool washer timers. New, refurbished and used Whirlpool timers are also available by auction and direct sale on eBay.
Finding a replacement timer requires knowing the Whirlpool washer's model number. This number appears on a manufacturer label located on the rim of the tub, underneath the washer lid. A compatible timer is located by selecting Whirlpool washers at the online parts stores and typing the model number in the designated search bar. AppliancePartsPros provides a video tutorial on how to replace a Whirlpool washer timer, and PartSelect provides numerous sets of installation instructions for easy reference.
