On our 12Flagstaff8528RKWS, our wh would only light once in a while even when new. I ended up removing the igniter and re-bending the probe. There are more than one dimension it has to meet. Page 12 shows the pictorial of the dimensions. Takes patience to get it, but once I got it bent correctly, it has worked flawlessly ever since.
