    Whirlpool L1373 repair attempt

    Hi, I was not able to power the board on using a 40w incandescent lightbulb, it seems the voltage drop is too great for small power draws, however it did confirm the short was gone, and the short was definitely in the trace repair arching to the kathode of the D006. The board powers up now and...

    Whirlpool L1373 repair attempt

    I'm worried that the repair will just keep arching over because it's no longer insulated by soldermask. However I'll try to make the slot bigger as ED suggested, and coat the repair with a clear varnish, or i could use a wiresock... I got a 5 pack, so i'm botchproof ;-) Not to worry, i'm not...

    Whirlpool L1373 repair attempt

    Right. I'm going to dremel the board tomorrow with a bristle brush, see if that gets rid of it. I was also thinking of cutting the repaired trace out entirely, and then repairing it with insulated copper wire, so the affected area is perfectly isolated from arching. I'm going to try that. I've...

    Whirlpool L1373 repair attempt

    Hi, thanks a ton for all the info provided so far. I still have not had time to do all the tests yet, but i have a theory of my own, and just wanted to run the validity of it by you guys... Is it possible that the repaired trace is arching over to D006 and creating a short this way because of...

    Whirlpool L1373 repair attempt

    Thanks for the lightbulb tip ED, I forgot all about that one. Will try this as soon as time permits. I must point out that LNK304PN was already replaced, and produces the same result as the LNK304 that was on the board when it failed... ie this is not likely to be the issue here. Included is...

    Whirlpool L1373 repair attempt

    I wired a switch between mains and the L1373 so i can test and immediately turn it off to preserve my dwindling stock of 22ohm resistors. I've noticed that I'm getting rather large arcs on the spot where I've repaired that bridge, however I'm having a hard time determining what exactly is...

    Whirlpool L1373 repair attempt

    Hi, I was lead here by google and found this thread. Unfortunately the TS abandoned the project because the main IC was apparently damaged. I am having an issue with this board as well. I've so far repaired the damage that was present on the board, however putting it back into the machine...
