Good afternoon, Mr. I come here with a problem, after a move the microwave oven stopped heating, turn on the light and rotate the plate normally, test the internal components with multimeter (open door sensors, thermal probes, fuses, transformer, capacitor, magnetron) and They all work well. Disassemble the electronic board and check resistors and electrolytes and they are ok. Desolder the Micro relay, apply 12v on the coil and continuity frame on the terminals.
This is the plate in question.
Performing more tests, place a test lamp at the 220v input to the transformer, it indicates that only voltage + arrives, do not turn on the lamp.
By chance testing the transformer of the electronic board (I did not know that it was switched), measuring continuity with the multimeter after touching the 30-second heating button, is that the device starts to function correctly, I turned on the test lamp, it turned on listen to the relay make connection and the magnetron makes noise (not try to heat anything yet). The pin of the transformer that I play with the multimeter left it marked here.
My question is whether it will be the transformer or the switches that are damaged, I am not electronic, just enthusiastic and googlero hehe. I hope someone can help me with this problem. Thank you so much!
