Symptoms of a failing Washer Door Switch include:

• The washer not starting or stopping unexpectedly during a cycle
• Error codes related to door closure issues displayed on the washer's control panel
• The washer door not locking properly or the lock mechanism not engaging
• The washer continuing to operate with the door open

Causes of a bad door switch can include wear and tear from frequent use, damage from repeated opening and closing of the door, electrical faults such as short circuits, or physical damage from mishandling or impact.

This OEM Whirlpool part is also compatible with some models from Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore.
