Appliance Repair Questions? Ask a Technician for Answers ASAP
The problem here is either going to be the magnetron, High voltage capacitor or High voltage diode. This is not a good DIY fix because factory test equipment will be needed to accurately diagnose the problem plus the unit stores lethal voltage even when unplugged.I recommend you take the unit down and take it to a experienced workshop to have it fixed. The cost would be anywhere between $150 - $250, Bearing in mind that most new units cost around $229 you may want to look for a new unit.After the warning given if you decide you want to fix this yourself and have a multi-meter and amp meter I would be happy to assist you further :)
