Whirlpool WPW10548509 Temperature Sensor OEM Part

The water flow during the fill step appeared extremely low. Confirmed the unit would make proper ice if I manually added more water. Through online research, found this was a common fail mode for this valve (low flow, continuous flow or no flow). During this search, the following video (https://youtu.be/By-i3gVMOdI) outlined how to use the onboard diagnostics which indicated the water level sensor wasn't working. The sensor hangs down in the water reservoir and is accessed by removing the water reservoir, then the bracket that holds the sensor and recirculation pump. The water inlet valve is located in the front left corner of the unit, below the ice bin, next to the condenser. The valve has one inlet and one outlet connection. To remove the lines, push on the ring that surrounds the line. Only a little water comes out when you disconnect the lines, assuming you turned the water off! Take note of how far the lines were inserted into the valve, reinsert these into the new valve by the same amount. After replacement the water flow was strong and filled the reservoir near the top of the overflow. Unit is back to making thick, clear ice again. I haven't tested the sensor, but I know it's working because the reservoir now fills in 35s whereas before it would run the max 2m and still not completely fill. A 1/4" nut driver removes all screws, but I did need a wrench to loosen the bottom door bracket to remove the protective panel to access the condenser/water inlet valve area. I removed some of the plastic from this panel to eliminate the need for a wrench the next time this needs to be removed for cleaning, etc.

Replaced both sensor and harness. This is the second time I've had this issue. The first time I just replaced the sensor. This time the harness was just as bad. This time I removed the metal bracket that the harness connectors rest on and wrapped the connections with electrical tape and vulcanizing tape. The new harness was much longer so I was able to put it in the corner out of the way in a service loop. I recommend doing this is you experience this moisture issue.

After reading some reviews it was clear to me I wasn't going to mess around with rewiring the grid so I ordered it complete along with the sensor. Install was easy as the parts were identical.
