Customer complained of Microwave not heating food but the Oven part works fine.
As usual,the culprit was a dead Magnetron and a shorted H.V Diode.
Replaced both faulty parts and the Microwave came back to life.
Warning!⚠️
Microwaves run on high voltages (H.V),above 1 Kilovolt, therefore it is advisable not to attempt any repairs if you are not a qualified Technician.
