Samsung Dryer DV22K6800EW - tripping breaker and curious black marks

[RSigg]

Hello! I have a Samsung DV22K6800EW 4.0 Cu.Ft. Electric dryer that I have already replaced the heating element (at about 1/5th the cost of the original machine, got off of eBay) on a year ago.

A few months ago it started tripping the breaker; I cleaned out the interior ducts fully though there wasn’t really any trapped lint inside. It still was tripping the breaker after 1-2 minutes and I figured I should start checking the electronics, starting with the breaker for good measure.

I finally got around to replacing the (30w, dual post) breaker the other day and it seemed to be working until we tried any temp over “Low” which would trip the new breaker. We experimented and even on low it would run for 40 minutes and then trip (I don’t know if this would have been the same on the previous breaker).

Last night I opened up the top to check for loose connections and everything still seems tight.

However when I was in there I did see two black/charred marks on the outside rear of the drum (see attached). I don’t remember those from last time; possibly leftover from manufacturing or sign of a short or overheating?

Next step I’ll check to see if there’s anything rubbing against the drum and post back here…

Any help greatly appreciated!

Well I think I solved my own issue! Even though none of the bundled wires were close to the drum, evidently at some point they were… It appears that the friction rubbed almost entirely through one of the wires (see attached).

So now I guess I have to figure out how to replace that wire, or just buy another heating element (which again seems stupidly expensive, although my previous seller is still hawking them for $100).
