The drum fails to spin during the spin cycle even though the motor is running. The shift actuator is unable to engage the splutch cam ring to drive the basket.
A repetitive clicking or grinding sound occurs during agitation or when the washer transitions between wash and spin cycles, indicating a worn or stripped actuator.
Washer agitates but never advances to spin, or vice versa. The actuator motor has failed and can no longer shift the transmission between modes.
Control board displays error codes related to tachometer signal or basket engagement because the optical speed sensor inside the actuator is damaged or sending incorrect data.
The wash plate or agitator does not move during the wash cycle. The actuator arm has failed to engage the agitation side of the cam assembly.
💡 Pro Tip: Diagnosing a Faulty Shift Actuator
Your part is likely the culprit if you notice any of the following:
⚠️ Washer drum does not spin even though the motor runs
⚠️ Loud clicking or grinding noise during agitation or cycle transitions
⚠️ Washer gets stuck in one mode and won't advance to the next cycle
⚠️ Error codes related to tachometer signal or basket engagement appear on the display
Quick test: Tip the washer back to access the bottom. With the washer unplugged, inspect the actuator arm on the cam assembly. If the arm is cracked, stripped, or the actuator housing is melted/discolored, replace immediately. The actuator also contains the tachometer – a faulty tachometer signal alone can trigger a no-spin error even if the motor is fine.
