Troubleshooting
If you encounter a problem, it often will merely be 
something minor. Before you call customer service, 
consider the suggestions and instructions below:
Problem
Suggestion
Neither the microwave’s display 
nor oven operates. 
Properly insert the plug into a grounded power outlet.
Remove the plug from the outlet, wait 10 seconds, then plug the microwave in 
again.
Reset the household circuit breaker or replace any blown fuses.
Plug a different appliance into the power outlet. If the other appliance will not 
operate, have a qualified electrician repair the outlet.
Plug the microwave into a different power outlet.
Oven display works, but the 
oven will not operate. 
Make sure the oven door is closed securely and completely.
Check to see if packing material or other materials are stuck to the door seal.
Check for damage to the oven door.
Press the Clear/Off key twice and attempt to re–enter cooking instructions.
Power goes off before the cook 
time has elapsed. 
If there has been a power interruption, remove the plug from the outlet; wait 
10 seconds, then plug the microwave in again. If there was a power outage, the 
time indicator in the display will show 00:00.
Reset the clock and any cooking instructions.
Reset the household circuit breaker or replace any blown fuses.
Press the Clear/Off key twice and attempt to re–enter cooking instructions.
Plug a different appliance into the power outlet. If the other appliance will not 
operate, have a qualified electrician repair the outlet.
Plug the microwave into a different power outlet.
Food is cooking too slowly. 
Make sure the oven is on a separate 20 amp circuit line. Operating another appli-
ance on the same circuit can cause a voltage drop. If necessary, move the micro-
wave to its own circuit.
Microwave is sparking, arcing 
occurs. 
Remove any metallic utensils, cookware or metal ties from the oven cavity. If using 
aluminum foil, use only narrow strips and allow at least one inch between the foil 
and the interior oven walls.
Turntable makes noises or 
sticks. 
Clean the turntable, roller ring and oven cavity bottom.
Make sure the turntable and roller ring are positioned correctly.
Using the microwave causes TV 
or radio interference. 
This is similar to the interference caused by other small appliances, such as hair 
dryers. Move your microwave further away from other appliances, like your TV or 
radio.
Note: If the oven is set to cook for more than 30 minutes at 100% power level, it will automatically adjust itself to a 
80% power level after 30 minutes to avoid overcooking.
