  • Red Hot Resister Problem on miller aead 200-LE

    I put this machine back together. Maybe some wires are crossed on the resistor. Not sure why it turned red hot in one spot. Is it a bad resistor, or maybe something plugged in wrong? Can I just replace one of the two that overheated? I would like to find a schematic. I clicked on another post that had a manual link but it defaults to the main page. I do have a manual I downloaded last year but I don't see this particular resisitor anywhere. I took a few pictures to see if anything strikes out as being hooked up wrong. ​Also wondering if AIRCO could have same part with different part #'s. I found ​a miller part with an airgas part # mil008951. Same description of part. Dual adjustable 180 watt 12ohm. There is no picture shown with any suppliers. The miller part # is 052782. The Airco part made by miller is $65 and the Miller part # is $105.

    Looks like all the wires have #'s accept one. The tabs are really rusty and was hard to unplug. Appears there was possibly broken tabs and alternative ones were used in its prior history of use.

    Determines open circuit voltage and doesn't like AC running through it

      I ordered the replacement part. Perhaps it was getting AC feed from the outlet wires. Does anyone have a diagram showing reference to the numbered wires? I can check to make sure the numbered wires are corresponding to correct component.

        Where can I get the wire diagram showing how each numbered wire to the panel switches, outlet, and this resistor I am replacing. I have downloaded the manual again. Diagrams don't show this detail. Does anyone have a picture they could send me showing the wire #'s used in the resistor. I don't want to ruin the replacement dual voltage resistor I am replacing. I am open to any suggestions on how to test each wire if I can not get a diagram or some pictures of the same machine. I greatly appreciate any help anyone can offer. Thank you

          If you go to the main page then click the menu icon (upper left) you will find a SUPPORT link. Go there and enter your serial number and you should be able to find a manual with a schematic; should include wire numbers. If it's not avail on line call Miller at 920-734-9821. They are very helpful.

            Ricknrolling, my apologies. I missed the line where you said you had already downloaded the manual. But give Miller a call and see if they can help you out.
