Wiring diagram

5 posts in this topic

  Looking for wiring diagram (3347814) for Whirlpool LA7780XSW0. Washer fixed, bad lid switch but curious as to how lid switch is wired. Never seen one that would agitate, no drain/spin yet timer continues to advance to end of cycle off position. This is an older model, 1987, with older type lid switch that I had not seen before.

  Thanks, but that's not the right one. I have many Whirlpool wiring diagrams including that one. On that model, if the lid switch fails, it won't drain/spin but the timer won't advance in drain/spin either. It will with the washer in question. Iv'e seen at least 4 variations in lid switch wiring in Whirlpool washers. It either breaks the drain/spin circuit and timer as in the diagram you provided, it breaks the L1 hot lead so nothing works, it breaks the neutral feed to motor and timer or it breaks the neutral feed to motor but not timer. None of those apply to the washer in question. No big deal, the washer is fixed, I just have this need to know how it works, and would like the diagram in my files.

No problem. That is the diagram published by Whirlpool on Service Matters for that unit. Must be some variant they produced that they don't list for that model.

  Ok, thanks for looking it up. According to the parts manual for that washer, the wiring diagram is #3347814 for versions 0 and 1, #3351746 for version 2.
