Whirlpool Washer LA7900XSW2 Timer will not advance

The Washer Door Switch is an OEM part for Whirlpool washing machines. This component is crucial for ensuring the washer operates safely by detecting whether the door is open or closed. The door switch prevents the washer from starting or continuing its cycle when the door is open, and it allows the machine to function only when the door is securely closed.

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.

This mechanical washer timer controls the sequence and duration of every cycle. Replacing a worn timer can restore proper advancing and reliable fill, wash, drain, and spin operation. What it does:

• Controls timing for fill, wash/agitate, drain, and spin steps
• Routes power to the motor, pump, and inlet valves at the correct times
• Advances the control dial automatically through each stage
• Failure can present as won't start, won't advance or stops mid-cycle, or skips functions (fill/agitate/drain/spin)

• 1 timer assembly

• Disconnect power before servicing
• Access the timer in the control console; remove the back cover, knob/retainer, and mounting screws as needed
• Transfer wires one at a time from the old timer to the new to maintain positions
• Reassemble and run a short cycle to verify proper operation
