If your Magic Chef dryer starts on its own or the dryer keeps running without you hitting start, the most likely culprits are electronic control parts rather than the drum or motor. Start with the motor relay, which can energize the motor unexpectedly, then check the timer if your model uses one. Next suspects are the main control board or other control boards, which can short or stick and send power to the motor. Less commonly the problem comes from the user touchpad, control panel, or user control and display board, especially if the start/cancel button is intermittent. Before you replace parts, test the relay and timer with a multimeter and consult your wiring diagram, and inspect control boards for burned or shorted components. If you need an exact replacement, enter your model number on RepairClinic.com to pull up the right motor relay, timer, control board, or touchpad for your dryer and get step-by-step repair help so you can fix it confidently.
01 - Magic Chef Dryer Motor Relay
If the dryer touchpad is working appropriately, it's possible the motor relay is defective. However, this is not that common of a problem. Before replacing the motor relay, check all the more commonly defective parts. If you determine that all of the other components are working properly, you can test the motor relay by using a multimeter and consulting the wiring diagram to help determine if it is malfunctioning.
