Hello all, I have a Samsung washing machine noise filter that I think has gone bad, I will post a picture and I was hoping one of you could tell me if I was doing my testing correctly , sorry for the bad picture, I am drawing a diagram that will be flat and I will post it later, but my question is this, I get 120 out of each leg of the noise filter, but only 40 volts across the output terminals, I am getting the correct voltages to the rest of the wiring harness, all the voltage coming out of the PSU is correct and all the voltages at the touchscreen/control board are correct, both the PSU and the touchscreen/control board are are brand new, and the touchscreen/control board was already flashed, any ideas yall might have would be great.

P.S. The readings on 3 and 4 are from the output to ground, so it is showing me the neutral is powered as well.

Something wrong, you should have the same voltage on the output as the input.
That is just an RF filter and should not affect the measured voltage level between input & Output.
