Panasonic Microwave NN-A770S getting hot on right side externally

I have a panasonic inverter combination microwave which gets very hot on the external RHS, just above the base. This happens when using the microwave only. As I have a service agreement with british gas, they came and changed the inverter and magnatron, but it still gets hot. This heat soon goes when the microwave function is stopped. BGas told me not to use the oven and wrote it off (cost £300 when bought 4yrs ago!) and are offering me £62 towards a replacement. I spoke with panasonic and they said that the area where it gets hot is where the inverter is and this is normal. Has anyone got a similar oven and can they tell me if this level of heat generation is normal? I really do not want to bin this oven as it works perfectly well, grill, convection and microwave. Thanks

    The original poster had this problem over a year ago, but it seems Panasonic have not made any changes. My NNA883W microwave gets a VERY hot spot on the casing on the right hand side at the position of the inverter, which must be getting extremely hot as having seen the insides of my microwave I know there is a quite thick plastic shield between it and the casing. I have also been told that this is normal, but as my previous microwave, the same model (for which it is a replacement) went off with a big bang after only six weeks I'm wondering just HOW hot is normal. The previous microwave also got very hot at this same spot, and that is no longer with us.

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.

Panasonic Model No. NN-S933BF Microwave Oven


No sorry the issue will be with eiher the inverter, the magnetron or the main timer board. There is a tracer signal that comunicates through these components and if it doesnt get to where it is supposed to go it wil just shut off, the big hint at that is the time interval. It is not something like a sensor heating up and causing a fault. it is not running long enough to get any thing hot it is in the electroincs. Too expoensive to repair, im sorry better to get a new one. Good Luck

Panasonic NN- A712 combination Microwave 1000w - Switches off after 20 seconds


The 22 seconds is the giveaway.

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.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.
