Hello friend, if your oven does not heat, you should check first and with caution that voltage reaches the hv transformer, disconnect the cables to the primary and check with a tester if there is a network voltage.

Hello friend, greetings, comments that you checked everything but you do not comment if you measured the transformer primary to see if voltage is coming, measure it as the colleague tells you if the supply voltage 110 or 220 does not reach you, be it your home outlet if it does not reach you Once you start the microwave, the safest thing is that you have the bad plate reley, the biggest one controls the transformer, change it and test now if the voltage is correct, the safest thing is that your magnetron is damaged so measure well in the tests. Change it and try another one, I'm sure it's the magnetron greetings. Atte Hector of Venezuela

greetings friend just from venezuela, if I test magnetron and perform the continuity tests, the 110 v shot is perfect today if the rain lets me out I will look for a magnetron and another transformer to do the test and the primary ones measured them in ohm and its value is very low 00.1 and I understood that it is 3 to 5 I don't know if I'm wrong? the secondary the ohmiaje if it's okay now friend hector to measure the voltage of the primary conetco the team excuse my doubt

Friend, I am sure that the problem is the magnetron, not the transformer, this fault is given by the magnetron, try another magnetron that is good and you will see greetings.

Ok friend if it was the magnetron because you didn't give me the solution,? Did you give it to the colleague that his answer was not the solution? I do not understand

A few weeks ago I repaired a lg that had the bad high voltage capacitor ... I tested it with the same microwave bulb in series
