Troubleshooting

Try the solutions suggested here first in order to avoid the cost of an unnecessary service call.

Nothing will operate

■Has a household fuse blown, or has a circuit breaker tripped?

Replace the fuse or reset the circuit breaker. If the problem continues, call an electrician.

■Is the microwave oven wired properly?

See Installation Instructions provided with your microwave oven.

Microwave oven will not operate

■Is the magnetron working properly?

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. See “Assistance or Service” section.

■Is the electronic microwave oven control set correctly? See “Microwave Oven Control” section.

■On some models, is the Control Lock on? See “Control Lock” section.

■On some models, is the Demo Mode active? See “Demo Mode” section.

Display shows messages

■Is the display showing “ERROR” during sensor cooking? The sensor is not detecting humidity. Check the food and the cover, then start the program again. See “Sensor Cooking.”

Fan running slower than usual

■Has the microwave oven been stored in a cold area?

The fan will run slower until the microwave oven warms up to normal room temperature.

Cooking times seem too long

■Is the cooking power set properly? See “Microwave Cooking Power” section.

■Are large amounts of food being heated?

Larger amounts of food need longer cooking times.

■Is the incoming voltage less than that specified in “Built-In Microwave Oven Safety?”

Have a qualified electrician check the electrical system in the home.

Microwave oven makes humming noise

■This is normal and occurs when the power supply switches the magnetron on and off.

Microwave oven drawer front looks wavy

■This is normal and will not affect performance.

Radio, TV or cordless phone interference

■Is the radio or TV receiver near the microwave oven? Move the receiver away from the microwave oven, or adjust the radio or TV antenna.

■Are the microwave oven door and sealing surfaces clean? Make sure these areas are clean.

■Is the cordless phone frequency 2.4 GHz?

Some 2.4 GHz-based cordless phones and home wireless networks may experience static or noise while the microwave oven is on. Use a corded phone, a different frequency cordless phone, or avoid using these items during microwave oven operation.
