| PROBLEM | CAUSE | SOLUTION |
|---|---|---|
| Microwave oven will not operate | 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 properly. | |
| Make sure Control Lock is off. | ||
| Make sure Demo Mode (on some models) is off | ||
| Arcing in the microwave oven | Soil buildup | Soil buildup on cavity walls, microwave inlet cover, cooking rack supports, and area where the door touches the frame can cause arcing |
| Turntable alternates rotation directions | This is normal and depends on motor rotation at the beginning of the cycle | |
| Display shows messages | A flashing or “PF” means there has been a power failure | Reset the clock |
| A letter followed by a number is an error indicator | Call for assistance | |
| Radio, TV or cordless phone interference | Proximity | Move the receiver away from the microwave oven, or adjust the radio or TV antenna |
| Soil | Make sure the microwave oven door and sealing surfaces are clean | |
| Frequency | Some 2.4 GHz-based cordless phones and home wireless networks may experience static or noise while microwave oven is on. Use a corded phone, a different frequency cordless phone or avoid using these items during microwave oven operation | |
| Fan running during cooktop usage | This is normal. The microwave oven’s cooling fan (on some models), which is separate from the vent fan, automatically comes on during microwave oven operation to cool the microwave oven. It may also automatically come on and cycle on and off to cool the microwave oven’s controls while the cooktop below is being used |

| PROBLEM | SOLUTION |
|---|---|
| Can I use a rack in my microwave oven so that 1 may reheat or cook in two levels at a time? | Only use the rack that is supplied with your microwave oven. Use of any other rack can result in poor cooking performance and/or arcing and may damage your oven |
| Can I use either metal or aluminum pans in my microwave oven? | Usable metal includes aluminum foil for shielding (use small, flat pieces). Never allow metal to touch walls or door |
| Sometimes the door of my microwave oven appears wavy. Is this normal? | This appearance is normal and does not affect the operation of your oven |
| What are the humming noises that I hear when my microwave oven is operating? | You hear the sound of the transformer when the magnetron tube cycles on and off |
| Why does the dish become hot when I microwave food in it? I thought that this should not happen | As the food becomes hot it will conduct the heat to the dish. Use hot pads to remove food after cooking. Dish may not be microwave safe |
| What does standing time mean? | Standing time means that food should be taken out of the oven and covered for additional time after cooking. This process allows the cooking to finish, saves energy, and frees the oven for other purpose |
| Can I pop popcorn in my microwave oven? How do I get the best results? | Yes. Pop packaged microwave popcorn following manufacturer’s guidelines or use the preprogrammed Popcorn pad |
| Do not use regular paper bags. Use the listening test by stopping the oven as soon as the popping slows to a pop every one or two seconds. Do not try to repop unpopped kernels. You can also use special microwave poppers. When using a popper, be sure to follow manufacturer’s directions. Do not pop popcorn in glass utensils | |
| Why does steam come out of the air exhaust vent? | Steam is normally produced during cooking. The microwave oven has been designed to vent this steam out the top vent |
