I’m new to electronics but have read elsewhere on this forum about a popular fault with Sharp microwaves being a strange protective ‘diode’ that is positioned across the terminals of the large capacitor together with a second tradionally labelled diode HVR-1X7 which is connected positive side to one side of the capacitor with the negative side to earth.
If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails. Forums New posts Search forums.
Microwave Ovens: 2X062H+HVR1X – MICROWAVE DIODE COMBINED…
Hi, I have a combination type Sharp microwave however the microwave function has failed. The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. I’m a bit bemused why you’re checking it with 12V – as it reads This diode however gives different test results to the original part which behaves under test as a tradional diode i. How do these diodes work and any suggestions as to the problem with my microwave?
I have purchased and fitted a replacement 2XH diode but the microwave still doesn’t work. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Crabber New Member Jan 19, The new protective ‘diode’ appears to work fine as it will not conduct in either direction as the symbol printed upon it would suggest yet the original part does conduct in one direction with 12v The tradional diode has been tested and appears to work correctly i. Thread starter Crabber Start date Jan 19, Perhaps I didn’t make myself clear enough.
I think I have found the answer to my question and one that has been raised on this forum previously. Welcome to our site! I knew the answer would be out there somewhere. However, it’s NOT a functioning part of a microwave, and the oven will work fine without it.
You must log in or register to reply here. In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse. Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the highest commodity value.
Its purpose in that configuration is to allow the capacitor to charge to a high voltage of the correct polarity only negative at the magnetron cathodewhich is blocked by the high-breakdown diode in the back-to-back arrangement. This kind of component is effectively two diodes in series, one with a high reverse breakdown voltage rating and the other with a much lower rating.

It is placed in parallel with the HV capacitor in the usual level-shifted magnetron power supply which uses a separate rectifier in series with the capacitor. To participate you need to register.

In any case, I suspect the “protection diode” is only designed to j current in the permanently-failed state, making it not worth much to you.
The replacement ‘diode’ shows Has anyone else any ideas? I don’t know precisely what condition is being protected against, but my guess is that a high reactive current circulating through the transformer-capacitor pursuant to a failed main rectifier or gassed-out maggie could cause one or both of these components to not “go gentle into that good night.
