I posted more or less the following as a comment on a old thread, but probably should have just started a new thread, so here goes...
I feel like a dope even though I don't think I've made a mistake. My brand new Samsung washer has the noise filter shown by the image following this paragraph. I needed to change the power cord (to one with a plug that lays flat against the wall) and was careful to pay attention to which terminals on the filter the line and neutral attached. But, now that I'm looking at the schematic diagram on the filter, it seems to disagree with what I'm 99% sure I observed.
The input leads (from the power cord) attach to terminals 1 and 2, and the output leads attach to terminals 3 and 4. On the base of the physical filter, terminal 1 is diagonally opposite terminal 4 (and terminal 2 diagonally opposite terminal 3). This physical orientation matters because of what I believe I observed when I disconnected the input leads. But first let me state something I'm sure of: the black output lead is definitely attached to terminal 4 and white output lead to terminal 3... I'm sure of this because these never got disconnected. However, this seems to contradict the schematic, which indicates that the hot output should be on terminal 3 and the neutral output should be on terminal 4.
When I disconnected the input leads, I was "sure" that the black input wire was diagonally opposite the black output wire. That would mean that the black input was on terminal 1 because it's the terminal diagonally opposite terminal 4, where the black output wire definitely is (and would mean the white input was on terminal 2). This input arrangement would be consistent with the schematic, but worries me because the output leads are connected in reverse (as described in the paragraph above). So now I'm doubting what I was previously sure of!
What happens if I am wrong about what I thought I observed and end up getting the input leads reversed as a result? What's the best way to make sure I'm getting it right (do I have to go to an appliance store and, when nobody's looking, open the top of another Samsung?)?
