What to Check First
- Check the power outlet. Make sure the power cord is securely plugged into a wall outlet. Note An extension cord or surge protector is NOT recommended.
- Reset the GFCI outlet if you have one. A GFCI outlet can trip as a result of an overloaded current or a faulty connection. Try resetting the outlet and retry the microwave.
- Check the Circuit Breaker Turn off the circuit breaker, wait 5 seconds, then turn the breaker back ON and retry the microwave.
- Test the Outlet With Another Device. This will identify if there is a problem with the microwave itself or if the problem is with the wall outlet. If the test product works, there is an issue with the microwave and will require service.
- If your microwave has no power, this can be caused by a poor connection to the outlet, the outlet isn't receiving power, or there is a failure with the unit requiring service.
