Photos / video:

second pic shows original fuse (small) and only generic option hardware store had. figured given the price and how far away second store was I would try the larger size. it fits, is not loose and I have already used the microwave once with the cover off (observing from a safe distance) to make sure nothing went wrong. would like to know if the connectors only touching a bit of the metal is a problem (placement in microwave shown in first pic)

after a little research I was able to find the fuse ( Danby 773.55 Dmw773w 20Amp Fuse | Genuine OEM Part )
