Panasonic Dimension 4 Microwave- Model NN D801. Whilst microwaving for 2 mins on high - heard a zapping noise. Didnt heat food. Front operating panel works. turntable still works. Any suggestions?


A "zapping noise" usually indicates a problem in the high voltage circuit. If it's an inverter oven, it should have provided you with a fault code. If a non-inverter, the most likely causes are a shorted high voltage rectifier or bad magnetron. But there are many other possible causes.

Kenmore 721.80403 microwave won't heat


If the turntable does move as well it is likely the inverter (power) or the Magnetron itself.

My Panasonic Microwave Genius 1300W will not heat up the food and the rotate dish spins and the sensor reheat will not heat up the food. Nor cook Pop Corn when pressing the buttons to 2:00 cook time. I...


Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.

Microwave light door turn table works but does not heat up food


In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.

Comination Microwave


Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part
I would think it's not a door switch problem since the oven and grill work.

I'd say this is a problem with the inverter or a bad magnetron.

More importantly, due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

Panasonic Microwave NN-A770S getting hot on right side externally


If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.
