Product review (2 stars): Both times things were working fine, I changed the filter and then had either ...
I've had this part fail twice in 6 years on my GE Model PFSS6PKXCSS refrigerator.  Both times things were working fine, I changed the filter and then had either no water, or just a trickle at the door, and barely or no ice. The first time I sprung ~170 bucks for the new part and sure enough that fixed it. The second time I was pretty upset....and found a much cheaper option. The GE part number WR17X20862 is EXACTLY the same as WR17X12512 with two exceptions. The first is, it costs ~30 bucks instead of ~170. The second is the tube that comes from the filter to the valve on the bottom right of your refrigerator is about 6 inches too short. I love how GE can charge 140 more for the same part with the only difference being one tube is 6 inches longer. I walked into my local ACE hardware and found a 12 inch adapter hose and an adapter fitting for 6 bucks and it works perfectly. I'm hoping if someone else has the same problem this will save them ~135 dollars ;-) The repair itself is quite easy, 20 mins tops.
