A failing or dying clothes dryer drive motor typically produces a distinct, loud electrical hum or buzzing noise when you press the start button, accompanied by a total failure of the drum to rotate or tumble. Other auditory symptoms of a bad motor include a high-pitched squealing sound caused by worn-out sleeve bearings or a rhythmic clicking as the internal centrifugal switch struggles to engage. You can troubleshoot motor faults safely using a digital multimeter. You can verify that your motor is failing when hearing a continuous electrical buzz while the drum remains stationary confirms that the motor windings are shorted or the rotor is mechanically seized, requiring complete replacement of the drive motor assembly.
