Replacement parts for a digital dryer timer can be purchased from the manufacturer or from third-party parts suppliers. Whirlpool sells replacement timer parts for its dryers on its website. Third-party websites that carry dryer timer parts include Sears Parts Direct and RepairClinic.
These sites also carry related parts, including circuit boards, electronic control boards and non-digital timers. Sears Parts Direct offers an online tutorial demonstrating how to repair a timer in most electric dryer models. The site recommends that consumers repairing their own dryers at home use manufacturer-approved parts and wear appropriate safety equipment. When in doubt about a repair, Sears recommends consulting a professional rather than continuing.
