The lid latch assembly signals the control board that the lid is securely closed. When the latch fails electrically or mechanically, the washer will not begin any cycle — drum stays silent after pressing Start.
A worn or broken latch solenoid prevents the lid from locking at cycle start or unlocking at cycle end, leaving you locked out of the drum or unable to run a wash.
An intermittent latch failure causes the control board to detect an open lid mid-operation and immediately halt the spin or agitation cycle as a safety measure.
A faulty W10404050 assembly is the most common trigger for lid-lock fault codes and the blinking red lid-lock indicator light seen on Whirlpool, Maytag, and Amana top-load platforms.
Because the lid must be confirmed closed before entering spin, a defective latch prevents the tub from reaching spin speed — load stays soaking wet at end of cycle.
💡 Pro Tip: Is Your Lid Latch the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Washer won't start or won't advance into the wash cycle
⚠️ Washer stops mid-cycle unexpectedly or pauses during spin
⚠️ Lid lock LED flashes repeatedly or displays a lid-lock error code
⚠️ Washer won't fill, drain, or spin even though it powers on
🔬 Diagnostic Tip: Unplug the washer and use a multimeter set to continuity mode. Probe the latch's switch terminals — a working latch shows continuity when the actuator is depressed and open circuit when released. No continuity in either state = replace the latch. Always disconnect power before probing.
