Styx said:nop a diode is a diode whether it is a HV or LV. The only difference is HV one's can have a higher forward volt drop but it is more like 0.8V as opposed to 0.6.
sounds like it is blown. Try using it as a diode with a batt and a res and measure volt drop over hte res to c if it is blown but it does sound like it is sorry

HV diodes are often a number of diodes in series, the voltage drop across them can be considerable.
First off - for Klifford - A WARNING! - the voltage and current levels in a microwave oven are exceedingly dangerous, and would almost certainly be fatal should you get a shock from them. The internal capacitor can stay charged up, and could also be dangerous - quite possibly fatal.
Secondly, as a professional microwave oven service agent for many years, it's unlikely the rectifier would be O/C, I've never known it happen, they invariably go S/C.

Do i need any special gig to test a HV diode (specifically HVR X1) found microwave ovens . My digital meter reads open both forward and reverse bias . Does that mean its gone . How can i be sure .
I'm using a fluke 78 .
Thanks
Kliff.
