How a Dryer Circuit is Configured and Installed

Indications of Incorrect Dryer Outlet Wiring
Electrical Question: My son wired my dryer outlet when moving the dryer from the basement. Now when I turn on the dryer it makes a loud buzzing noise and then shuts off. While doing this it smells warm. I thought it was the dryer motor so I replaced it, it still made the same noise and shut off. Could it be that the outlet is not wired right?

This electrical question came from: Janice, a Homeowner from Nevada, Missouri

• Janice, yes it could be that the dryer outlet is not wired right, and there could be a serious problem with the way your son installed the new wiring for the dryer.
• From what has been described in this question, do the following IMMEDIATELY:
  • The circuit for the dryer should be turned off until the problem has been identified and corrected otherwise there could be an electrical shock hazard and possible damage to the dryer and internal components.
• You should have a licensed electrical contractor make the repairs.
