Beth for Model Number MMV4205BAQ Turntable stopped turning. Microwave appeared to be changing turntable setting to off. Worked temporarily after re-setting turntable to on. Eventually stopped turning even when returning setting to on. Disconnected and then re-connected motor drive and problem appeared to be fixed, but now again switching to off with temporary fix with re-setting to on. Should we try replacing the motor drive or is it more likely a control board problem? Thanks!
Answer Beth, It would be recommended to check to see if there is constant voltage to the motor. If the motor is getting 120 Vac but not turning then the motor would be the issue and if there is not power then the issue will be the control board. Read More...
