Whirlpool WPW10341320 Water Inlet Valve OEM Part

Replaced both inlet valves, no joy. Upon further inspection, found ice maker harness extremely tight at lower freezer door hinge, clamped in place right at a pivot point. Essentially the harness is held in place and rotates with the door. 6 wires broken inside. Splice repair and ice maker now works. Most likely will have to replace harness eventually. Unless there is more slack inside the freezer door this will probably happen again. Very poor design.

Replaced both water control valves. This unfortunately did not fix the issue but was an important troubleshooting step. After replacing both valves and having the same issue I troubleshot the water path, single control valve - up to filter housing - down to the water cooler/reservoir "S" (made sure this was not frozen and blocked) - back to double control valve) and narrowed it down to the water filter housing being a restriction. We don't use a water filter as the fridge is plumbed to the RO system. I bypassed the filter housing (and the water cooler/reservoir) with tubing directly from the single control valve to the double control valve. Water pressure out of the dispenser is now normal. Items to note. 1. the fridge locking feet use a VERY small 1/4in wrench.. make sure you have a wrench that small 2. the backside of the fridge was relatively clean. The compressor, fan, drip pan were MUCH cleaner than expected (Good design) 3. coils can be cleaned from the FRONT without having to pull the fridge out (Good design)

I replaced the water inlet valve

The 2 parts where easy to get to from the back bottom access panel. Remove the 6 screws on the access panel. Then I removed 2 screws holding the water input valve. Then I disconnected the plug. There were 3 water lines attached pulled the clips holding on the water lines. The whole repair took 30 mins.
