Good night mates, I have a microwave whirpool that is burning me the 10 amp diode of the Control Card. Now check the micro swich and they are OK ... I am now checking the HVR-1X 7 diode with alternating voltage and it is the following: before the 128 volt diode (the voltage is a little high in this zone) and after the diode me measures 124 volts and I switch it to digital voltage and it measures me 51 volt dc. Will my diode be okay? Because in alternating I get very high it is almost in short

The most likely is the solution that gives Hector, but it is good to check the transformer that is not short and be very sure of the door nut, which is not bad, also measure the megatron filament that does not measure with the body, good luck.
