Troubleshooting and error codes
| Problem | Possible Causes | What To Do |
|---|---|---|
| Oven will not start | A fuse in your home may be blown or the circuit breaker tripped. | Replace fuse or reset circuit breaker. |
| Power surge. | Unplug the microwave oven, then plug it back in. | |
| Plug not fully inserted into wall outlet. | Make sure the 3-prong plug on the oven is fully inserted into wall outlet. | |
| Control panel lighted, yet oven will not start | Door not securely closed. | Open the door and close securely. |
| CONTROL LOCKED appears on display | The control has been locked. | Press and hold CLEAR/OFF for about 3 seconds to unlock the control. |
| OVEN TOO HOT FOR SENSOR COOKING---USING ALTERNATE METHOD appears on display | One of the sensor cooking buttons was pressed when the temperature inside the oven was greater than 200°F. | These features will not operate when the oven is hot. The oven will automatically change to cook by time (follow the directions in the display) or once the oven is cool enough, the sensor features will function normally. |
| Food browns on top much faster than on the bottom | Rack has been placed in the "high" position. | Always use the rack in its “low” position. |
| Oven temperature fluctuates during cooking | The cooking element cycles on and off to maintain the oven temperature at the desired setting. | This is normal. |
| Vent fan comes on automatically | The vent fan automatically turns on to protect the microwave if it senses too much heat rising from the cooktop below. | This is normal. |
| During Bake, Roast or Fast Bake (after preheating), the vent fan will automatically come on to cool the oven components. | This is normal. | |
| SENSOR ERROR appears on the display | When using a Sensor feature, the door was opened before steam could be detected. | Do not open door until steam is sensed and time is shown counting down on the display. |
| Steam was not detected in a maximum amount of time. | Use Time Cook to heat for more time. |
