Motor is on but not spinning and has a burnt smell

I’d open it up and see if you can isolate the smell. Motor Coupling If the washer won’t spin or agitate the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission. Drive Motor If the washer won’t spin or agitate the drive motor might be defective. This is not common. Check all of the other related parts to this symptom before replacing the motor. If the motor is visibly burned out or physically damaged, replace it.
