Just saying hello Started by MichaelaJoy Yesterday at 6: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Has anyone else any ideas? I know that it may work fine without it but not necessarily if it is fitted and faulty.

You must log in or register to reply here. Started by fastline Yesterday at 8: 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.

Sharp Combi Microwave and Strange Diode

Engineering of a cheap Chinese appliance is all about pushing the envelope and trimming the margins of safe failure. In any case, I suspect the “protection diode” is only designed to carry current in the permanently-failed state, making it not worth much to you. I note your 14th November response to a similar query ” It’s a special diode, created this this specific purpose – no idea how it works, and care even less ” I’ll assume that you still don’t know and perhaps hrv should both steer clear of microwaves!!

Thread starter Crabber Start date Jan 19, In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse. I have purchased and fitted a replacement 2XH diode but the microwave still doesn’t work.

Hi, I have a combination type Sharp microwave however the microwave function has failed. Potentiometer Questions Started by norbss Yesterday at 2c062h Its purpose in that configuration is to allow the capacitor to charge to a high voltage of bvr correct polarity only negative at the magnetron cathodewhich is blocked by the high-breakdown diode in the back-to-back arrangement.

I knew the answer would be out there somewhere. Articles Top Articles Search resources. However, it’s NOT a functioning part of a microwave, and the oven will work fine without it. I think I have found the answer to my question and one that has been raised on this forum previously.

The tradional diode has been tested and appears to work correctly i. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Hi Nigel and thank you for your reply. Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the highest commodity value. From a posting by Carl Willis who has posted the below on fusor. 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.

If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails.

Welcome to our site! 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 2x602h 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. How do these diodes work and any suggestions as to the 2x062n with my microwave?

The HV rectifier yvr not appear to have failed as it has 7. The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. 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 It is placed in parallel with the HV capacitor in the usual level-shifted magnetron gvr supply which uses a separate rectifier in series with the capacitor.

The replacement ‘diode’ shows Perhaps I didn’t 0062 myself clear enough. 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.
