Drive motor tachometer error

Check tachometer coil on back of motor — measure resistance (typically 100-200 ohms)
Inspect motor connector for burnt or corroded pins
Spin drum by hand — resistance or grinding indicates bearing failure
If tachometer tests good, the MCU is not reading the signal — replace MCU
Pro Diagnostic Tip
Applies to models starting with 110.xxxxx (Whirlpool platform). The tachometer is a small coil behind the motor rotor — it is a separate, inexpensive part that can be replaced without swapping the entire motor.
