High voltage fuse blowing
Added 2022-05-03 23:38:01 +0000 UTCWhile I'm travelling there's going to be a burst of shorter videos I've prepared in advance to keep you entertained while I'm away from my normal bench.

Let's start with blowing a high voltage fuse and addressing a common magnetron myth.

TV's, iPhone's, Windows OS ...them bugs get everywhere.

I always leave the magnatron in them as have obviously heeded them warnings. Not really sure I have a use case for a magnatron anyway though. :)

2022-05-05 10:49:49 +0000 UTCSorry for the stupid question but If I=V/R, how are you pumping 1A without high voltage if the resistance of the fuse is fixed. Again apologies if this is extra stupid.

2022-05-04 21:47:39 +0000 UTCSharp commercial microwave ovens were the only oven i have seen that used a high voltage fuse , rated 5KV @.55 A about 2 inch long glass cartage with the spring to pull-back and stop arcing.

2022-05-04 16:22:06 +0000 UTCModern domestic microwaves use an Aluminium oxide ceramic, older and comercial may well contan Berylium. Don't crush or break it the dust is very toxic and carcinogenic. Getting it in a cut is also not recomended.

2022-05-04 09:16:28 +0000 UTCOver the years I have had a couple of microwaves suddenly stop providing any heating but with the light and turntable still continuing on at least one occasion there was a distinctive pop, I guess this was probably the high voltage fuse blowing.
