A washer timer controls the washing machine’s functions by determining when to change the cycles and how long each cycle runs. The timer has several switches that are activated by a rotating cam. Each switch triggers a different component in the washer to perform a particular action.
The timer is made up of numerous tiny parts that can malfunction when they become old, disintegrate or when they become exposed to electrical damage and cause the machine not to work properly. A defective timer can prevent the washer from advancing through the cycles or cause certain functions of a cycle to fail.
