I know of at least two Panasonic inverter microwaves that failed within a 5 year period of ownership.
Mine emitted white smoke warming up some tea while I was in another room. I hope to God it wasn’t beryllium.
I still have a Panasonic OTR microwave, but it’s inverterless. It appears to be an improved design of a GE model from the same OEM.
- Jeff_Brown 3y agoOh no. Is that something that happens? Mine has smelled a little like metallic smoke lately.

- alexdbird 3y agoWe have a Panasonic Inverter microwave here, must be 20 years old. It works great and I have never noticed any interference with WiFi or Bluetooth, both of which also get a lot of use in the kitchen. Just another anecdata point!
- xattt 3y agoThe earlier inverter models sound like they’re workhorses. The problematic ones I knew of were from around 2012 - 2014.
- londons_explore 3y agoProbably burnt paint from the inside of the waveguide. Happens frequently when the mica sheet that covers the injection port gets moisture from steam (who'd have thought - steam in a microwave?!?) Simple fix is to replace the mica (a few cents from AliExpress) and use steel wool to get rid of any carbon residue around the injection port.
- xattt 3y agoIt sounded like there was no magnetron load on the power supply, because the cooling fan was spinning a little faster and the interior was a little brighter. This was during the few seconds between the smoke show and from me pulling the plug. There was indeed a char mark on the mica sheet, but the beryllium terror at the time was enough for me to chuck it.
- londons_explore 3y agoYou would expect less load on the power supply if there was an arc causing a short in the waveguide.
