Question about Panasonic NN-T783SF 1350 Watts Microwave Oven
I have a Panasonic Microwave Model NN-T783SF. I set the clock to 30 minutes and instead of pressing the timer function button I pressed start. The Microwave was empty. At approx 20 min there was an electrical burning smell and I realised what I had done. By this time the display was no longer showing. I pressed stop and opened the door. the whole microwave was very warm. When I reached behind to turn the power off at the wall the back was hot. I have not tried to use it since as I wan to find out the likely damage and if it is worth repairing. I am an electrician but have very limited electronics knowledge. Thanks for any advise you can give. Cheers, Jason
Hi James, Well it sounds to me as the Magnatron burnt out. There are tests you can so, so to familiarize you with what it looks like by copying the link. http://www.ebay.co.uk/itm/PANASONIC-INVERTER-MICROWAVE-OVEN-MAGNATRON-2M236-M42-NN-SF550W-1000W-/262200547027?hash=item3d0c5ed6d3:g:ucsAAOSwSHZWdkWb#ht_1687wt_726
If you are prepared to open up the unit there are a couple of checks you can do on the mag. If you see the item described above in your microwave, chances are its that. With all the video's readily available to view there is little or no point in my describing to you for what to do next so I will advise you look at 'YT' and search for 'TESTING A MAGNATRON' This should hopefully lead you to the conclusion that your Magnatron is faulty.
If it is not, then there is a possibility that the door switches could be at fault, but it's best do do this in a step by step approach to eliminate the issue.
WORD OF WARNING: I have studied electrics but even with my knowledge I received a 250v JOLT across my body due to being careless. I touched the case at the same time as the LIVE in the microwave. DO NOT MAKE MY MISTAKE. IF YOU do not feel confident to remove the cover on the microwave, then DON'T and if you do then then MAKE DOUBLE SURE IT'S NOT PLUGGED IN. I won't forget so easily If fix another.

The problem I had experienced with the Door not opening easily will be resolved by removing the micowave oven top cover with a tamper proof torx head, replacing the door switch and reinstalling the top cover.
