I opened the case and immediately got…

…a whiff of magic smoke.

Some sort of big green resistor?

Anyway. It’s toast.

Next one, I won’t leave it plugged in.

    Yeesh, yeah. That’s supposed to be downstream from the fuse and rated for 5W. I dunno what happened but it wasn’t good.

    Sadly, sometimes you just have to get out the .45, play taps and put her down…

    I’d read the bands, but it don’t matter. You ain’t gonna repair that–cheaper to get a new one.

    Well there’s yer problem 😉

    *IF* it is a bad component you could replace the big honkin resistor. If it was a power fluck then yeah, not leaving it plugged in is the best plan. It’s not too often that you let the magic smoke out of a resistor like that.

    Joel, I found a teardown video online and that is a 100 ohm resistor, could be 1 watt but I can’t tell the size from the video. I agree that fixing it is not likely possible as you have to figure out why that part smoked, can be something downstream that caused it. Here is the video link for fun. https://youtu.be/LiDJp4VBJ_A
    From the digi key site, that seems to be a 101 x 10K resistor with 1% tolerance, so basically a one meg ohm resistor. https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code-5-band. Get a new one at Home Depot or Lowes or the Bezos store.

    Ignore the 100 ohm, that was if it was a 4 band, but it is a 5 band, so the multiplier is 10K, ugh! Getting rusty for lack of use.

    Suspect your power – as far as I know it is normal/OK to leave them plugged in so as to monitor circumstances of increased consumption, and I have. But it’s good to know this happened.
    BTW is your phone/computer/anything electronic plugged into a really heavy duty Isotel? I ask because I’ve always used one, had a mild lightening strike in my yard that blew it out and was very glad everything was plugged into it. And there is a surge protector on my electric panel. Electrical stuff is so unpredictable.

  8. Andrew says:

    What Zelda said (as usual, she’s one smart lady.) Make sure you’ve got some sort of surge protector/line cleany thingamabob. Will save you much in the future.

    Worked at a job where they were willing to buy a new computer and monitor every 9 months to a year but wouldn’t splurge for a friggin $100.00 surge protector. Idiots.

  9. John says:

    Is/are traces on the circuit board burn damaged? If so a jumper wire may fix. You might lift / unsolder one end of the resister (so it is isolated from the circuit) and put your ohm meter across it to see if it is open. I can’t make out the color bands well from the picture but this might help:

    Damn Joel, why did you let the magic smoke out of the wires?

  11. Joel says:

    In the boonies, carelessness kills. 🙂

  12. Ben says:

    That cooked resistor is most likely a symptom of your problem, but not the main problem itself. It’s time to obtain a new KAW and get on with life in the Gulch.

  13. Joel says:

    That’s the plan.

To the stake with the heretic!
