If I answer enough questions - good answers or bad - I'll be an expert too. So "Expert" here means nothing more than they're an expert at giving answers or opinions. Doesn't mean they're "Right" or "Good" answers or opinions, they're just answers or opinions. And opinions are like a**holes. Everybody has one. Some stink. And no - I'm not referring to any particular person or persons here. Just making a general statement.member level is now "expert" while yours is only "moderator".
That "expert" is a milestone he has been shooting for since joining. And many of his answers have fallen into the latter category to get to the milestone. I have the same level but don't consider myself one. But it means the world to him.If I answer enough questions - good answers or bad - I'll be an expert too
Murphy's law clearly states that in that accidental contact, the part that failed and smoked the fuse will be the most hard to find and expensive to replace. On that basis, actually the diac or diode or thermo sensor pictured has a good chance to have survived in trade of greater suffering to repair.accidental touched it against the circuit board. The wire wound fusible resistor instantly turned black and started smoking. I'll see if I damaged the red part after replacing the resistor today.
This thread also serves to remind us all that it is much wiser to remove power before taking things apart. That applies to veteran workers and Newbies alike.
Are those your expert opinions?My guess now is that it has not been damaged because a package that small can not handle a lot of heat without mechanically failing.
It is useless to test a diode with an Ohm meter, the range does not offer sufficient current to FWD bias it.The simple test will be to measure the resistance with an ohm meter. I have used diodes that have an identical appearance, which is why I suggested a diode. AND the diode forward voltage drop varies in a linear manner as the temperature changes.
. A resistance check will tell . A diode will have two very different values. And of course a diode should have a band marking polarity.
