Question about Microwave Ovens
Could be magnatron, diode, capacitor, transformer, control board or switches. Be careful, high voltage can kill you. Mag is only suspect. It would be wrong to replace it without checking the other components. They are not hard to check but be sure to unplug the unit so you live thru the repair.

Magnatron is suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing the magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
