|---|---|
| Microwave oven will not operate | Check the following: - Household fuse or circuit breaker If a household fuse has blown or a circuit breaker has tripped, replace the fuse or reset the circuit breaker. If the problem continues, call an electrician. - Magnetron Try to heat 1 cup (250 ml.) of cold water for 2 minutes at 100% cooking power. If water does not heat, try the steps below. If microwave oven still does not operate, call for service. - Door Firmly close door. On some models, if a packaging spacer is attached to inside of the door, remove it, then firmly close door. If a message about the door appears in the display, the door has been closed for 5 minutes or more without the microwave oven being started. This happens to avoid unintended starting of the microwave oven. Open and close the door, then start the cycle. - Control Make sure control is set property. Make sure Control Lock is off. Make sure Demo Mode (on some models) is off. |
