The Whirlpool WP8299780 Dryer Timer is a critical component that controls the drying cycle in your Whirlpool dryer. It acts as the brain of the drying process, dictating how long each cycle lasts by controlling the flow of electricity to various components such as the heating element and the drum motor. This timer is designed specifically for 230-volt dryers, which are commonly found in commercial laundry facilities. When you select a drying cycle in your dryer, the WP8299780 Timer starts the program. It ensures that the dryer runs for the specified time, preventing clothes from being over-dried or remaining damp. A faulty timer can cause a number of issues, including cycles running for too short or too long, or the dryer not responding to cycle selections.
