This diode or high voltage diode is used in microwaves. Do the symptoms i describe seem to go with the way the microwave is acting.

Unfortunately ordinary solid state diodes do not like hv and would quickly fail in this application.

What does a diode do on a microwave. It was arcing between the top of the magnatron tube and the shielding on the microwave. But it just wont heat up anything. It is actually many solid state diodes stacked is series to insure that the reverse current does not cause a breakdown.

Im not certain just what the true function of the diode is in this case i know how a diode. It makes noise the lights light up fine the controls all work and it beeps when done etc. A diode or rectifier should cause a voltage drop in this circumstance one of approximately 3 volts.

It is an electrical current control device that ensures power flows in one direction and not the other way. I was hoping the diode was bad because otherwise i dont know whats wrong with the microwave. I just used what the microwave oven manufacturer listed in the parts section.

You can test a new diode with the same procedure of creating a series circuit and confirm that there is an appropriate drop in voltage. Did i test the diode properly. As to the price once you know the diode specs or type number or equivalent you can search online to find suppliers and also the manufacturers brand of the diodes.

After all they know their product best. It does everything but heat up the food. A special diode called an avalanche diode is used.

This appears based on some googling to be very common and the hvr 1x3 seems to be a common replacement. The diode is a rectifier which converts mains ac to dc. I tested the diode and it is bad for sure.

If you read the same voltage as the battery then the diode is bad and needs to be replaced. Its an hvr 1x diode. My main question is did the magnatron possibly go bad and arc causing the diode to blow or would the diode going bad cause the magnatron to arc.

If your microwave produces no heat heats inconsistently or gets noisy replacing this part can be the solution. Special about testing these types of diodes.
