    Re: USING IH COIL And IH power supply of C451 BIZHUB ON C452

    OK no matter Phil i understand you I WILL REPAIRE THE ORIGINAL BOARD
    I ALREADY DO THAT AND HAVE SOMTHING WRONG ON IH COIL THIS IS WHY I M NOT HAPPY TO GET A NEW IH SUPPLY CARD
    WHAT ABOUT IH COIL OF C451 IT CAN WORK on C452 IH SUPPLAY I SEE THAT IT HAVE TWO ADITIONAL (GRD) ??

    It is obvious you are set on trying this so go ahead and try it! Personally I wouldn't want to take a chance of blowing out the main board, etc. Especially with a high voltage board.

    I Try it and appaire no probleme

    what i have as new is that i repaire the IH board for the second time all is gone fine until i listen bad sound like "tiktikitik" without waiting until losting the two transistor i cut the electricity as resulte
    - the transistors on baord were very hot
    - i can say that the original IH coil is fine
    - so have to look on IH baord

    Buddy i also pull tricks like this. But that means you are on your own.
    Hope the building its in is insured.

    You probably have a bad cap on there.
    If that omron you are talking about is probably a relay and it ticking is not your problem. Its a high current switching supply.
    The ticking is it switching on and then protection or error condition switching it back of again.
    Yes that will heat up semiconductors because lots of current is pulsing thru them.
    Whatever

    Here's another thought, how about if he's in a country that parts aren't easily available, or something like that. I guess sometimes you need to do what you need to do. Got to give the person some credit just for being able to solder and swap components on the board. Not sure many of the "new style" "IT techs" as I call them ever soldered a thing in their life!

    I've tried things like this before in the shop for troubleshooting purposes but wouldn't feel comfortable putting in a customers office with the wrong board.

    The temp fail safes should still work independent and fooling thermistors on these machine would take some master hackery.
    So i say go for it in second thought change out all the electrolytic caps on the print don't have any detail for those prints.

    We care to much for 3de world shit holes like the one i find myself in.
    The world is in chaos and anarchy not far off because we "care" aka liberal bullshit.
    Whatever

    thks allan

    yes the question i have now is why the transistor more very hot and burned after some bad sound ?
    i suppose to have prob in IH coil but when i try an ather i get the same result which mean the prob is caming from IH supply board it self

    Its a difficult, and that is what you are taking on. When these components go they take other components with them.
    My guess is your problem started with bad caps.
    On SMPS it tends to be the original cause of failure taking the semiconductors shunt resistors and even coils with it.
    If you don't replace all the bad stuff at the same time it could cause repeated failure.
    Whatever

    Re: USING IH COIL And IH power supply of C451 BIZHUB ON C452

    At first i want to thank you all for tour hekp

    Today i have repear by changing all SMPS on thé original board
    As conclusion it s impossible to use an IH POWER SUPPLY OF C451 on C452
    But IH Coil yes se can by making some modification on it
