My microwave does not heat and makes loud buzzing noise…
Tested diode…showed infinity…checked bad…replaced with locally purchased part…part number did not match parts breakdown for my model # but was told it would work by salesman…does part number matter?
Tested magnatron…showed less then 1 ohm (.4 & .5) per terminal and infinity to case?
Tested capacitor…showed 0 at each terminal and infinity to case…ordered part and replaced but did not resolve problem
Unsure of where to go from here…any assistance would be greatly appreciated!
