Panasonic Inverter Micro-Wave repair (Many other models similar or compatible )

In this video I'm repairing the household microwave oven a Panasonic Inverter type model NN-SD670S. After determining the cause of the failure, I'll try to extend the tutorial content including a complete demonstration on how Inverter type micro-wave works and how to make a general diagnostic procedure.

Many Panasonic Inverter micro-wave models are very similar inside using many common parts and configuration, so, this video will cover many other models.

Other models known to have very similar configuration
NN-SD698S
NN-ST-678S
NN-ST658W
NN-SD691S
NN-ST681S
NN-SD671S

NN-ST661S
NN-ST661B

I purchased the relays on eBay, the cost was aprox $10 usd for 3 units including shipping. There are other sources where you can get parts, here are a few suggestions:
Digikey, Element14, Newark, Mouser, etc, it's also possible to find a Panasonic service center near your location that will supply you with parts.

Fixing something that can still render good services is way better than throw away and waste.

Thank you for watching and I hope you like this type of video…

Mon Ami ! So pleased to see you my friend! I have been waiting in hopes you would resume my training.

I am really glad to see you again Pierre. I do not pretend to be able to fix any electronic appliance so I mostly leave them alone. I hope we will be seeing you again. Thanks for the video.

So good to finally hear you, Pierre! In your usual calm and rigorous ways. Great fix, great example of intelligent restoration!

Great to see you back on the tube. I hope that this is the first of many videos to come. You have been missed.

Pierre! I missed hearing from you, glad to see you back in the game. I totally agree that taking the time to try repairing stuff is the best course, our society throws out too many still-serviceable items. It seems like relays are a common failure point, as I've had to replace them in kitchen oven controls too due to burnt contacts.
Super happy to see you again! 😃

Welcome back!
Good advice on avoiding cross-threading or double-cutting when replacing screws in soft material.

Hi Pierre, so good to se a video from you again, nice repair instead of just buying a new one, but 99% can't do that unfortunately, I was thinking of how you where getting along last week, but haven't got to write to you. All the best my friend and a good old handmade thumbs up to you.
